Comprehensive Information on 24-Core & 12-Core Control cable Combo
1. Product-Specific Details
1.1 Specification Parameters
The 24-core & 12-core control cable combo is engineered with precise specification parameters to meet the demanding requirements of signal and command transmission in industrial automation scenarios. At the core of its electrical specifications is the conductor cross-section, uniformly set at 1.5mm² for each core across both 24-core and 12-core variants. This cross-sectional dimension is the result of rigorous analysis of typical current demands in industrial control systems, where control signals typically operate at low currents (ranging from a few milliamps to several amps). The 1.5mm² size strikes an optimal balance between current-carrying capacity and material efficiency: it provides sufficient ampacity to handle the maximum current of control signals without overheating, while avoiding the unnecessary weight and cost associated with larger conductors.
In terms of electrical performance, the cable exhibits low DC resistance, a critical parameter for maintaining signal integrity. The high-purity electrolytic
Copper Conductors contribute to a resistance value of approximately 0.012 ohms per meter at 20℃ for the 1.5mm² core. This low resistance ensures minimal voltage drop during signal transmission, even over extended distances (up to 100 meters, a common length in industrial wiring), preventing signal attenuation that could lead to misinterpretation of control commands by PLCs or sensors. The cable also has a high insulation resistance, measured at over 1000 megaohms between adjacent cores and between cores and the sheath, ensuring effective isolation between individual signal paths. This insulation resistance is maintained across the cable’s operating temperature range, preventing leakage currents that could cause signal interference or short circuits.
Mechanical specifications are tailored to the industrial environment’s physical demands. The cable has a minimum bending radius of 6 times its outer diameter for fixed installations and 8 times its outer diameter for dynamic applications (such as wiring in moving parts of electromechanical equipment). For the 12-core variant, the typical outer diameter is 12–14mm, resulting in a minimum fixed bending radius of 72–84mm; the 24-core variant, with an outer diameter of 16–18mm, has a minimum fixed bending radius of 96–108mm. This
Flexibility allows the cable to be routed through tight spaces in control cabinets, around equipment components, and along complex paths without damaging the conductors or insulation. The cable also boasts a tensile strength of 1500 Newtons for the 24-core variant and 1000 Newtons for the 12-core variant, enabling it to withstand the mechanical stress of installation (such as being pulled through conduit) and the occasional tension from equipment vibration.
Thermal specifications define the cable’s operational range. It has a continuous operating temperature range of -15℃ to 70℃, with a short-term overload temperature tolerance of up to 90℃ for durations of less than 2 hours. This range covers the typical temperature fluctuations in industrial workshops, from cold winter conditions in unheated facilities to warm environments near heat-generating equipment (such as motors or furnaces). The cable’s temperature coefficient of resistance is 0.00393 per ℃ for the
Copper Conductors, ensuring predictable changes in resistance with temperature, which allows system designers to account for minimal signal variations in their automation logic. Additionally, the
PVC Sheath has a Vicat softening temperature of 80–85℃, indicating the temperature at which it begins to soften, ensuring the sheath remains structurally intact under normal operating conditions.
1.2 Distinctive Features and Applications
One of the most distinctive features of this cable combo is its "dual-core-count" configuration, offering both 24-core and 12-core options in a single product package. This design addresses the diverse wiring needs of industrial automation systems, where some segments require high-density signal transmission (calling for more cores) and others need streamlined, low-density connections (requiring fewer cores). Unlike purchasing separate 24-core and 12-
Core Cables from different suppliers, this combo eliminates the need for multiple procurement processes, reduces inventory complexity, and ensures compatibility between the two cable variants (as they share the same
Conductor Material, insulation, and sheath specifications). This compatibility is critical in systems where the 24-core and 12-core cables interact, such as in a "main-branch" wiring architecture where the 24-core cable serves as the main signal trunk and the 12-core cables act as branch lines to individual devices.
Another standout feature is the cable’s flexibility, derived from its multi-strand copper conductor design. Unlike solid copper conductors, which are rigid and prone to breaking when bent, the conductors in this cable are composed of 19 strands of 0.3mm fine
Copper Wire (for the 1.5mm² core), twisted together in a precise lay pattern. This stranding not only enhances flexibility but also improves the cable’s resistance to fatigue from repeated bending—a common occurrence in automated equipment with moving parts (e.g., robotic arms, conveyor systems). The flexibility also simplifies installation in confined spaces, such as the interior of control cabinets with dense component layouts, where the cable must navigate around terminals, circuit boards, and other equipment without excessive force.
In terms of applications, the cable combo is highly versatile across industrial automation scenarios. In PLC control systems, the 24-core variant is ideal for connecting PLC hosts to distributed I/O modules, where it can transmit dozens of input signals (from sensors) and output commands (to actuators) simultaneously. This centralized transmission reduces the number of cables needed, minimizing clutter in control cabinets and simplifying troubleshooting (as technicians can trace multiple signals to a single cable). The 12-core variant, meanwhile, is well-suited for connecting I/O modules to individual devices, such as a single sensor or actuator, forming a modular wiring structure that eases system expansion—adding new devices only requires extending the 12-core branch lines, not modifying the 24-core main trunk.
For sensor wiring, the cable’s
Multi-Core design enables the parallel transmission of signals from multiple sensors. In a typical production line, for instance, a single 24-core cable can connect to 4–6 sensors (with 4–6 cores allocated per sensor), eliminating the need for separate cables for each sensor. This not only reduces material costs but also cuts down on installation time, as technicians only need to route and terminate one cable instead of multiple. The cable’s flexibility is particularly advantageous for surface-mounted or embedded sensors, which often require wiring in tight spaces or around curved equipment surfaces.
In electromechanical equipment wiring, the cable is used to connect control circuits of motors, pumps, valves, and other machinery. The 1.5mm² conductor provides sufficient current for the low-power control circuits of these devices (e.g., motor start/stop signals, valve position control), while the PVC sheath protects against the oil, dust, and minor mechanical impacts common in mechanical workshops. The cable’s flame retardancy also adds a layer of safety in environments where flammable materials are present, as it self-extinguishes if exposed to fire, preventing the spread of flames.
1.3 Material Selection and Design Style
The material selection for this control cable combo is a critical factor in its performance, durability, and suitability for industrial environments. The conductors are made of high-purity electrolytic copper, with a purity level of 99.95% or higher. This high purity is essential for minimizing electrical resistance, as impurities (such as iron, nickel, or oxygen) would increase resistance and lead to signal attenuation. The electrolytic copper also undergoes an annealing process during manufacturing, which softens the metal and improves its ductility—key properties for forming the multi-strand conductors that contribute to the cable’s flexibility.
The insulation layer surrounding each conductor is made of high-quality PVC (polyvinyl chloride) compound, chosen for its excellent electrical insulation properties, mechanical strength, and cost-effectiveness. The
PVC Insulation has a dielectric strength of 20–25 kV/mm, which is well above the voltage levels of industrial control signals (typically 24V DC or 230V AC), ensuring no electrical breakdown between adjacent cores. The insulation is also formulated to be resistant to oil and chemicals commonly found in industrial settings, such as mineral oils, lubricants, and mild solvents, preventing swelling or degradation that could compromise insulation performance.
The outer sheath of the cable is another layer of PVC, but with a modified formulation to enhance mechanical durability and flame retardancy. This sheath material has a higher tensile strength and abrasion resistance than the insulation PVC, protecting the internal cores from physical damage during installation and use. It is also treated with flame retardant additives that meet UL94 V-0 or GB/T 18380 standards, meaning it self-extinguishes within 10 seconds of being removed from a flame and does not drip flaming particles. The sheath is available in a standard gray color, which is highly visible in industrial environments, making it easy for technicians to identify and trace the cable during maintenance.
In terms of design style, the cable follows a compact, cylindrical structure that prioritizes functionality and ease of handling. The 24-core and 12-core variants have a round cross-section, which ensures uniform stress distribution when the cable is bent, reducing the risk of localized damage to the insulation or sheath. The cores are arranged in a concentric or stranded pattern within the sheath, with a filling material (typically a non-hygroscopic polyester yarn) used to fill any gaps between the cores. This filling material provides additional structural stability, preventing the cores from shifting during installation or use, and also helps to maintain the cable’s round shape.
The cable’s overall design also incorporates a ripcord—a small, strong thread embedded between the insulation and sheath—for easy stripping. When technicians need to terminate the cable (connect it to terminals or connectors), they can pull the ripcord to quickly and cleanly remove the outer sheath, without the need for specialized tools. This feature saves time during installation and reduces the risk of damaging the internal cores while stripping.
1.4 Production Process
The production process of the 24-core & 12-core control cable combo is a highly controlled, multi-stage operation that adheres to strict quality standards to ensure consistency and performance. The process begins with the manufacturing of the copper conductors. High-purity electrolytic copper ingots are first melted in a furnace at 1085℃ and cast into continuous copper rods with a diameter of 8mm. These rods are then drawn through a series of diamond dies in a wire-drawing machine, which reduces their diameter to 0.3mm— the size of the individual strands in the 1.5mm² core. During drawing, the copper wire is annealed in a continuous annealing furnace (operating at 300–400℃) to restore flexibility and ductility lost during the drawing process.
Once the individual
Copper Strands are ready, they are twisted together in a stranding machine to form the 1.5mm² conductors. For each core, 19 strands of 0.3mm copper wire are twisted at a lay length of 10–15mm (the distance over which one strand completes a full twist around the center). This lay length is optimized to balance flexibility and conductor stability: a shorter lay length increases flexibility but may reduce tensile strength, while a longer lay length improves strength but decreases flexibility. The stranding process is monitored to ensure the strands are evenly distributed and tightly twisted, with no gaps or overlaps that could affect electrical performance.
Next, each
Stranded Conductor undergoes insulation extrusion. The conductor is fed into an extruder, where the PVC
Insulation Material is melted at 160–180℃ and forced through a die that coats the conductor with a uniform insulation layer of 0.8–1.0mm thickness. The extruder’s line speed is synchronized with the conductor feed rate to ensure consistent insulation thickness, and the process is monitored by an online laser gauge that measures the insulation diameter in real time. Any deviations from the specified thickness trigger automatic adjustments to the extruder, ensuring the insulation meets the required specifications. After extrusion, the
Insulated Conductors are cooled in a water bath to solidify the PVC, then dried to remove any moisture.
Once all
Insulated Cores (24 for the 24-core variant, 12 for the 12-core variant) are produced, they are collected for cabling. The insulated cores are fed into a cabling machine, which twists them together into a compact bundle. The cabling process uses a planetary stranding mechanism that rotates the cores around a central axis, creating a stable, round cable core. During cabling, a polyester yarn filling material is added to fill gaps between the cores, ensuring the bundle maintains a uniform shape. A binding tape (typically a polyester tape) is then wrapped around the bundled cores to hold them in place and provide additional protection.
The final step in the production process is the extrusion of the outer PVC sheath. The bundled cores (with binding tape) are fed into a second extruder, where the sheath PVC material is melted at 170–190℃ and extruded over the bundle to form a sheath of 1.2–1.5mm thickness. The extruder die is sized to achieve the desired outer diameter of the cable (12–14mm for 12-core, 16–18mm for 24-core). After extrusion, the
Sheathed Cable is cooled in a water bath, then passed through a puller to ensure uniform tension and straightness. A ripcord is embedded between the binding tape and the sheath during this process, inserted via a small guide tube before the sheath is extruded.
Quality control testing is integrated into every stage of production. Before extrusion, the copper strands are tested for purity (using spectroscopic analysis) and tensile strength (using a tensile testing machine). During insulation and sheath extrusion, online thickness gauges and dielectric strength testers monitor the insulation and sheath properties. After production, samples from each batch undergo a battery of tests, including:
Electrical tests: Insulation resistance testing (using a megohmmeter), dielectric strength testing (applying high voltage to check for breakdown), and DC resistance testing (measuring conductor resistance).
Mechanical tests: Tensile strength and elongation testing (for conductors, insulation, and sheath), bending testing (repeatedly bending the cable to its minimum radius), and abrasion resistance testing (rubbing the sheath against a rough surface to check for damage).
Environmental tests: Oil resistance testing (immersing the cable in mineral oil for 24 hours and checking for sheath swelling), flame retardancy testing (exposing the cable to a flame to verify self-extinguishing behavior), and temperature cycling testing (exposing the cable to -15℃ and 70℃ alternately to check for insulation cracking).
Only after passing all quality control tests are the cables wound onto spools for packaging and shipping.
2. General Product Information
2.1 Packaging
The packaging of the 24-core & 12-core control cable combo is designed to protect the cable during storage, transportation, and handling, while also ensuring ease of use for industrial customers. The primary packaging format is the cable spool, available in two sizes to accommodate different cable lengths: small spools (holding 100 meters or 200 meters of cable) and large spools (holding 500 meters or 1000 meters of cable).
Small spools are typically made of high-impact polypropylene (PP), a lightweight yet durable plastic that resists cracking and deformation. The spools have a flanged design, with flange diameters of 200mm (for 100m spools) and 300mm (for 200m spools), to prevent the cable from slipping off during unwinding. The inner core of the spool is reinforced with ribbing to support the weight of the cable, and the surface is smooth to avoid abrasion of the cable sheath. Large spools, designed for heavier cable lengths, are constructed from plywood or steel. Plywood spools have a flange diameter of 500mm–800mm and are treated with a water-resistant coating to prevent warping in humid environments. Steel spools, used for the heaviest 1000m lengths, are made of galvanized steel to resist corrosion and have a load-bearing capacity of up to 500kg.
Before winding the cable onto the spool, the spool is inspected to ensure it has no sharp edges, splinters, or debris that could damage the cable. The cable is then wound onto the spool using a computer-controlled winding machine that maintains a constant tension (30–50 Newtons, depending on cable size) to ensure even layering. Each layer of cable is separated by a thin sheet of kraft paper to prevent the cable from sticking together and to reduce friction during unwinding. After winding, the cable end is secured to the spool with a non-adhesive cable tie to prevent it from unwinding during handling.
To protect the cable from environmental damage, each spool is wrapped in a multi-layer covering. The first layer is a transparent polyethylene (PE) film that adheres tightly to the cable surface, creating a barrier against dust, moisture, and minor scratches. The second layer is a heavy-duty woven polypropylene bag, which provides additional mechanical protection against impacts and punctures. For large steel or plywood spools, an optional weatherproof tarp can be added, secured with bungee cords, to shield the cable from rain, snow, or direct sunlight during outdoor storage or transportation.
Each spool is labeled with a comprehensive information tag, attached to the spool’s flange with a stainless steel clip. The tag includes: product name (24-Core & 12-Core Control Cable Combo), conductor specification (1.5mm²
Flexible Copper), sheath material (PVC), cable length, batch number, production date, compliance certifications (e.g., UL, CE, GB), and the manufacturer’s name, address, and contact information. For the combo package, an additional label is included that lists the contents of the combo (e.g., 1 x 24-core spool, 1 x 12-core spool) and their respective lengths.
For bulk shipments, multiple small spools (10–20 units) are packed into corrugated cardboard cartons. The cartons are double-walled for strength and lined with foam inserts to prevent the spools from shifting. Each carton is labeled with the same product information as the individual spools, plus the total number of spools and the carton’s gross weight. Large spools are shipped individually, with their flanges protected by thick cardboard edge guards to prevent dents or scratches during loading and unloading. These edge guards are secured with adhesive tape and reinforced at the corners, ensuring the spool’s structural integrity is maintained throughout transit. For international shipments, all packaging materials comply with the International Safe Transit Association (ISTA) standards, which specify requirements for protecting cargo during global transportation, including resistance to compression, vibration, and impact.
2.2 Transportation
The transportation of the 24-core & 12-core control cable combo is managed through a logistics process tailored to the industrial nature of the product—prioritizing the protection of the cable’s mechanical and electrical integrity, on-time delivery, and compliance with industrial safety regulations. The choice of transportation mode depends on the shipment volume, destination, and customer’s delivery timeline.
For domestic shipments within a single country, road transportation is the primary method, utilizing fleet trucks equipped with either flatbed or enclosed trailers. Flatbed trailers are used for large plywood or steel spools, as they allow for easy loading and unloading with cranes or forklifts. The flatbed surface is inspected before loading to ensure it is clean, level, and free of debris that could puncture the cable’s packaging. Large spools are placed on the trailer with a minimum distance of 30cm between them to prevent collision during transit. Each spool is secured to the trailer using heavy-duty steel chains and ratchet straps, attached to the trailer’s built-in anchor points. The chains are wrapped around the spool’s flanges, and the straps are tightened to a tension of 500–800 Newtons, preventing rotational movement or lateral shifting even during sudden vehicle maneuvers.
Enclosed trailers are preferred for small spools packed in cartons, as they provide a controlled environment shielded from weather, dust, and theft. The interior of enclosed trailers is lined with non-abrasive padding along the walls and floor to prevent the cartons from rubbing against metal surfaces. Cartons are stacked on standard wooden pallets (1.2m x 1.0m) and secured with stretch wrap—applied in a crisscross pattern to ensure the stack remains stable. The pallets are then loaded onto the trailer using a forklift and secured to the trailer’s floor with L-shaped metal brackets, which are bolted to the trailer and prevent the pallets from sliding.
During road transit, drivers are provided with a detailed route plan that avoids roads with excessive potholes, sharp turns, or low overpasses (critical for large spools). The maximum driving speed is limited to 80 km/h on highways and 40 km/h on rural or urban roads to minimize vibration. For shipments exceeding 500 km, drivers are required to make mandatory stops every 3 hours to inspect the cargo: checking the tightness of securing straps, verifying that packaging remains intact, and ensuring no spools or cartons have shifted. Any loose straps are retightened immediately, and damaged packaging is temporarily repaired with waterproof tape to prevent further exposure.
For international shipments, sea freight is the most cost-effective option for large volumes, while air freight is used for urgent orders (e.g., replacement cables for production line downtime). Sea freight involves loading the spools into 20-foot or 40-foot shipping containers. Large spools are placed in the container first, with wooden blocks nailed to the container’s floor to brace the spools and prevent movement. The blocks are positioned at the base of each spool’s flanges, creating a stable barrier against shifting during the voyage. Small spools in cartons are then packed around the large spools, filling any empty spaces with foam inserts to absorb vibration. The container is sealed with a tamper-proof metal seal, and the seal number is recorded in the shipping documentation for tracking.
Air freight requires stricter compliance with weight and size restrictions. Small spools in cartons are repacked into lightweight, durable plastic crates (each weighing no more than 30kg) to meet airline cargo limits. The crates are labeled with "Fragile" and "Handle with Care" stickers, and loaded onto air cargo pallets secured with netting. Air freight shipments are also subject to security screening in accordance with International Air Transport Association (IATA) regulations, where the cargo is scanned to ensure no prohibited items are included.
Regardless of the transportation mode, the shipment is tracked in real time using a cloud-based logistics management system. Both the manufacturer and customer receive access to a dashboard that displays the shipment’s location, estimated time of arrival (ETA), and any delays (e.g., traffic congestion, port holds). If a delay is anticipated, the logistics team proactively notifies the customer and offers solutions—such as rerouting the shipment or arranging for expedited delivery at no additional cost for critical orders.
Upon arrival at the destination, the cargo is unloaded using the same equipment and procedures as during loading. For large spools, a crane with a spreader bar (to distribute weight evenly across the flange) is used to lift the spool from the trailer or container. The customer is invited to inspect the shipment before signing the delivery receipt: checking the number of spools against the packing list, verifying that the packaging is intact, and conducting a visual inspection of the cable for any signs of damage (e.g., sheath scratches, bent conductors). Any discrepancies or damage are documented on the delivery receipt, with photographs taken as evidence. The manufacturer is notified immediately, and a resolution—such as replacing damaged cables or issuing a partial refund—is initiated within 24 hours.
2.3 Shipping
The shipping process for the 24-core & 12-core control cable combo encompasses all steps from order confirmation to final delivery, involving coordination between the manufacturer’s sales, warehouse, and logistics teams, as well as external freight partners. It begins when the customer places an order, specifying the quantity of each core variant (24-core/12-core), cable length per spool, and delivery address. The sales team first verifies the order against inventory levels: if the product is in stock, the order is processed within 24 hours; if not, the team provides the customer with a production timeline (typically 5–10 business days for standard orders) and confirms the ETA.
Once the order is confirmed, the warehouse team retrieves the required spools from inventory or coordinates with the production department to fulfill custom orders. Each spool is scanned using a barcode system to track its batch number, production date, and specifications—ensuring the correct product is selected for the order. The spools are then moved to the shipping preparation area, where they undergo a final quality check: inspecting the cable’s sheath for cracks, verifying the label information matches the order, and ensuring the packaging is intact.
The next step involves preparing the shipping documentation, which includes:
Commercial Invoice: Details the product description (24-core & 12-core control cable combo), quantity, unit price, total value, currency, and payment terms. It also includes the customer’s tax identification number and the manufacturer’s export license (for international orders).
Packing List: Lists each item in the shipment (e.g., 2 x 24-core spools, 3 x 12-core spools), with individual weights, lengths, and spool types (plastic/plywood/steel).
Bill of Lading (BOL) or Air Waybill (AWB): Serves as a contract between the manufacturer (shipper) and the carrier. The BOL for sea/road transport includes the shipment’s origin, destination, container number, and seal number; the AWB for air freight includes the flight number and cargo handling instructions.
Certificate of Compliance (CoC): Verifies that the cable meets international industrial standards (e.g., IEC 60227 for Flexible Cables, UL 1015 for Electrical Wires) and includes test reports from the manufacturer’s quality control lab.
Certificate of Origin (CoO): Confirms the country where the cable was manufactured, required for customs clearance in most countries to determine applicable tariffs.
For international shipments, additional documentation may be required based on the destination country’s regulations. For example, shipments to the European Union require a Declaration of Conformity (DoC) to comply with the CE marking directive, while shipments to the United States need to meet Underwriters Laboratories (UL) certification requirements. The logistics team works with a certified customs broker to ensure all documentation is complete and formatted correctly, avoiding delays in customs clearance.
The logistics provider is then scheduled to pick up the shipment from the manufacturer’s warehouse. The provider’s driver arrives with a vehicle matching the shipment’s size and presents a pickup order, which is verified by the warehouse team. After loading, the driver and warehouse manager sign the pickup receipt, confirming the quantity and condition of the cargo.
Customs clearance is a critical phase for international shipments. The customs broker submits the documentation to the destination country’s customs authority, paying any applicable duties, taxes, or fees on the customer’s behalf (unless the customer has requested to handle these directly). Customs officials may conduct a physical inspection of the shipment—typically 5–10% of shipments are inspected randomly—to verify that the goods match the documentation. If the inspection passes, the shipment is released for delivery; if discrepancies are found, the broker works with customs to resolve the issue (e.g., providing additional test reports) within 48 hours.
The final delivery to the customer’s site is coordinated by the local logistics partner. The customer is contacted 24–48 hours before delivery to schedule a time that aligns with their production schedule (e.g., outside of peak manufacturing hours to avoid disrupting operations). On the delivery day, the driver unloads the cargo using the customer’s on-site equipment (or the provider’s equipment, if requested) and assists with placing the spools in the customer’s designated storage area (e.g., a warehouse or control cabinet room). The customer signs the delivery receipt, which is scanned and sent to the manufacturer as proof of delivery. A digital copy of all shipping documentation is also emailed to the customer for their records.
2.4 Samples
The provision of samples is a key component of the customer support process for the 24-core & 12-core control cable combo, allowing industrial customers to evaluate the product’s compatibility with their automation systems, installation processes, and environmental conditions before committing to a bulk order. The manufacturer offers samples that are identical to full-production cables in terms of materials, specifications, and manufacturing processes—ensuring the sample accurately represents the performance of the final product.
Customers can request samples through multiple channels: direct contact with the sales team via phone or email, submission of a sample request form on the manufacturer’s website, or through authorized industrial distributors. When a sample request is received, the sales team collects essential information to tailor the sample to the customer’s needs: desired core variant (24-core, 12-core, or both), sample length (standard length is 1–2 meters, with custom lengths up to 5 meters available), quantity of samples (1–3 samples per variant), and the customer’s specific application (e.g., PLC wiring, sensor connection, or electromechanical equipment) to provide relevant technical documentation.
Sample production follows the same quality control protocols as bulk orders. The copper conductors are made from the same high-purity electrolytic copper, the PVC insulation and sheath from the same industrial-grade compounds, and the stranding and extrusion processes are identical. Each sample undergoes a miniaturized version of the bulk quality tests: insulation resistance testing (using a portable megohmmeter), flexibility testing (bending the sample to its minimum radius 10 times), and visual inspection for sheath uniformity. Only samples that pass all tests are dispatched.
Samples are packaged in a compact, industrial-grade envelope or small cardboard box. Each sample is wrapped in a transparent polyethylene film to protect it from dust and moisture, with a label attached that includes the product specification (core count, conductor size, sheath material), batch number, and production date. For combo samples (both 24-core and 12-core), the two variants are placed in separate compartments within the box, with a divider to prevent friction between them.
Shipping of samples is prioritized to meet the customer’s testing timeline. For domestic customers, express courier services (with delivery in 1–2 business days) are used; for international customers, expedited air freight (3–5 business days) is standard. The cost of samples is typically waived for customers planning to place bulk orders (minimum order quantity of 1000 meters), while a nominal fee (covering material and processing costs) is charged for small or repeat sample requests. Shipping costs may be borne by the manufacturer for qualified customers or by the customer, depending on the terms agreed upon during the request.
Along with the physical samples, the manufacturer provides a comprehensive sample kit that includes:
Technical Data Sheet (TDS): Details the cable’s electrical parameters (DC resistance, insulation resistance), mechanical properties (tensile strength, bending radius), thermal range, and compliance with industrial standards.
Installation Guide: Offers step-by-step instructions for stripping the cable (using the integrated ripcord), terminating it to PLC terminals or sensor connectors, and testing for continuity.
Test Report Summary: Summarizes the results of the sample’s quality tests, including insulation resistance values and flame retardancy test outcomes.
Compatibility Chart: Lists compatible connectors, terminals, and equipment (e.g., PLC models from Siemens, Allen-Bradley; sensor brands like Banner or Omron) to help the customer verify integration with their existing system.
After the customer receives and tests the samples, the sales team follows up within 7–10 days to gather feedback. This feedback covers aspects such as the sample’s flexibility during mock installation, compatibility with the customer’s equipment, and whether the electrical performance meets their signal transmission requirements. If the customer identifies any issues (e.g., difficulty stripping the sheath), the technical support team provides immediate solutions—such as adjusting the sheath formulation for future orders or offering a modified sample with a thinner sheath. This feedback loop ensures the customer’s needs are addressed before a bulk order is placed, reducing the risk of post-purchase issues.
2.5 After-Sales Service
The after-sales service for the 24-core & 12-core control cable combo is designed to support industrial customers throughout the product’s lifecycle—from installation to end-of-use—aligning with the long operational lifespan of industrial automation systems (typically 10–15 years). The service framework focuses on minimizing production downtime, ensuring system reliability, and providing cost-effective maintenance solutions.
2.5.1 Technical Support
Technical support is available 24/7 for critical issues (e.g., cable failure causing a production line shutdown) and during standard business hours (8 AM–6 PM, Monday–Friday) for non-urgent inquiries. Customers can access support via a dedicated technical hotline, email, or video conferencing—with response times guaranteed: 1 hour for urgent issues and 4 hours for non-urgent requests.
The technical support team consists of engineers with 5+ years of experience in industrial automation wiring, who can provide guidance on:
Installation Support: Detailed advice on routing the cable in control cabinets (e.g., avoiding proximity to high-voltage Power Cables to prevent electromagnetic interference), using the ripcord for efficient stripping, and torque specifications for terminal connections (typically 0.5–1.2 N·m for 1.5mm² conductors). For complex installations (e.g., wiring for robotic arms), the team can provide 2D/3D diagrams of recommended cable paths.
Troubleshooting: Step-by-step diagnosis of common issues, such as signal interference (resolved by checking for damaged insulation or improper grounding), high conductor resistance (caused by poor terminations or conductor damage), or sheath cracking (addressed by verifying compliance with the operating temperature range). The team may request test data (e.g., insulation resistance readings) or photographs of the issue to provide targeted solutions.
System Integration: Guidance on integrating the cable with third-party equipment, such as PLCs, sensors, or variable frequency drives (VFDs). This includes verifying voltage compatibility, recommending shielded connectors for high-noise environments, and advising on cable length limits to avoid signal attenuation.
For on-site support needs (e.g., resolving a critical wiring issue that cannot be fixed remotely), the manufacturer dispatches a field engineer within 24–48 hours for domestic locations and 48–72 hours for international sites. The engineer carries a toolkit with specialized equipment (e.g., insulation resistance testers, cable fault locators) to diagnose and resolve the issue on-site, minimizing production downtime.
2.5.2 Warranty Service
The manufacturer offers a 5-year warranty for the 24-core & 12-core control cable combo, covering defects in materials and workmanship. The warranty is valid for customers who purchase the cable directly from the manufacturer or authorized distributors and install it in accordance with the manufacturer’s installation guidelines.
To file a warranty claim, the customer must notify the after-sales team within 14 days of discovering the defect, providing: the order number, batch number (from the spool label), photographs/videos of the defect, a description of the issue (e.g., sheath degradation, conductor breakage), and proof of installation (e.g., installation logs or photos). The team reviews the claim within 48 hours and may request additional information—such as a third-party test report for complex defects—to validate the claim.
If the claim is approved, the manufacturer offers three resolution options:
Replacement: The defective cable is replaced with a new cable of the same specification, shipped via expedited transport to minimize downtime. The customer is responsible for returning the defective cable (at the manufacturer’s expense) for failure analysis.
On-Site Repair: For minor defects (e.g., localized sheath damage in a hard-to-reach area of a control cabinet), a field engineer is dispatched to repair the cable using a specialized repair kit (including heat-shrink tubing, conductive paste, and insulation tape) that restores the cable’s performance to factory standards.
Refund: In rare cases where replacement or repair is impractical (e.g., widespread defects in a large shipment), the manufacturer issues a full refund of the purchase price, processed within 5–7 business days of claim approval.
The warranty explicitly excludes defects caused by improper installation (e.g., bending below the minimum radius, using incompatible crimp connectors), misuse (e.g., exposing the cable to chemicals not listed in the TDS, such as strong acids), neglect (e.g., failing to clean oil or dust from the sheath, leading to insulation degradation), or external events (e.g., fires, floods, or accidental impact from heavy machinery). To maintain warranty validity, customers are required to store all relevant records—including installation logs (signed by certified technicians), maintenance reports (documenting regular inspections), and delivery receipts—for the entire 5-year warranty period. These records may be requested by the manufacturer during warranty claim reviews to verify compliance with installation and maintenance guidelines.
In cases where a warranty claim is denied (e.g., due to evidence of improper installation), the manufacturer still provides support to resolve the issue. The technical team offers guidance on how to rectify the problem (e.g., replacing the damaged section of cable with a new one) and may provide the required replacement parts at a discounted rate. This approach ensures that even if the issue is not covered by warranty, the customer can still access cost-effective solutions to minimize production downtime.
2.5.3 Recycling and Environmental Services
Recognizing the industrial sector’s growing focus on sustainability and circular economy practices, the manufacturer offers dedicated recycling and environmental services for end-of-life or defective 24-core & 12-core control cables. This program addresses the environmental challenges of traditional cable disposal—such as PVC and copper waste in landfills—and aligns with global regulations (e.g., the EU’s RoHS Directive, China’s National Solid Waste Management Law) that restrict the disposal of electronic and electrical waste.
For end-of-life cables (typically after 10–15 years of service, matching the lifespan of industrial automation systems), customers can initiate the recycling process by contacting the after-sales team. The team coordinates with ISO 14001-certified recycling partners to arrange for the collection of old cables. Collection is available for both small quantities (e.g., a few spools from a control cabinet upgrade) and large volumes (e.g., cables from a factory-wide automation overhaul). For large-scale collections, the manufacturer covers the transportation cost, while small-quantity collections may require the customer to ship the cables to a designated recycling facility (with the manufacturer reimbursing shipping fees upon receipt).
The recycling process follows a structured, material-specific workflow to maximize resource recovery:
Sorting and Inspection: Upon receipt, the cables are sorted by type (24-core vs. 12-core) and condition (end-of-life vs. defective) to determine the most efficient recycling path. Defective cables with reusable components (e.g., intact copper conductors) are separated for targeted material recovery.
Sheath and Insulation Removal: The PVC sheath and insulation are stripped from the copper conductors using mechanical stripping machines. This process avoids the use of harsh chemicals, reducing environmental impact. The stripped PVC materials are then shredded into small pellets (2–5mm in size) to remove contaminants (e.g., dust, oil residue) through a washing and drying process.
Copper Recovery: The exposed copper conductors are processed in a two-step refining process. First, the conductors are melted in a low-emission furnace (operating at 1085℃) to remove any remaining insulation particles. The molten copper is then cast into ingots, which are further refined using electrolysis to achieve a purity level of 99.99%. This high-purity copper is sold to manufacturers of new Electrical Wires and cables, closing the material loop.
PVC Repurposing: The cleaned PVC pellets are blended with virgin PVC (at a ratio of up to 30% recycled material) to produce secondary plastic products. These products include non-critical industrial components (e.g., cable spools, protective caps for terminals) and construction materials (e.g., PVC piping for non-potable water systems). Any PVC that cannot be repurposed (e.g., highly degraded material) is sent to licensed energy recovery facilities, where it is incinerated in controlled environments to generate heat, with emissions treated to meet EU Emission Standards (EN 12952).
Waste Disposal: Non-recyclable materials (e.g., small amounts of adhesive residue from labels) are disposed of in compliance with local hazardous waste regulations. These materials are sent to specialized landfills with liners to prevent soil or water contamination.
After recycling, the manufacturer provides the customer with a Recycling Certificate within 2 weeks. This certificate includes: the quantity and type of cables recycled, the weight of materials recovered (typically 95%+ for copper, 80%+ for PVC), the environmental impact metrics (e.g., CO₂ emissions reduced by 0.5kg per kg of copper recycled, water saved by 10L per kg of PVC repurposed), and the recycling partner’s certification details. The certificate is useful for customers seeking to meet corporate sustainability goals (e.g., carbon neutrality targets) or comply with environmental reporting requirements (e.g., ESG disclosures).
For defective cables returned as part of warranty claims, the manufacturer follows the same recycling process instead of disposing of them. This ensures that even non-functional cables contribute to resource conservation, reducing the product’s overall environmental footprint. The manufacturer also publishes an annual sustainability report that includes data on cable recycling volumes, material recovery rates, and environmental impact reductions—providing transparency to customers about the program’s effectiveness.
2.5.4 Customer Feedback and Continuous Improvement
The manufacturer views customer feedback as a foundational driver of product and service innovation, integrating a systematic feedback mechanism into every stage of the customer lifecycle. This process ensures that insights from industrial customers—who use the cable in real-world automation scenarios—are translated into tangible improvements for the 24-core & 12-core control cable combo.
Feedback is collected through multiple, targeted channels to capture diverse perspectives:
Post-Delivery Surveys: Sent via email 7 days after delivery, these surveys focus on the shipping experience (e.g., "Was the delivery on time?" "Was the packaging intact?") and initial product quality (e.g., "Does the cable match the ordered specifications?" "Is the labeling clear?"). The survey uses a 5-point Likert scale for quantitative data and includes open-ended questions (e.g., "What improvements would you suggest for the packaging?") to gather qualitative insights.
Post-Installation Interviews: Conducted 30–45 days after installation (to allow time for real-world use), these 15–20 minute interviews are led by the sales team. The interviews explore installation-related challenges (e.g., "Did the ripcord function as expected?" "Was the cable flexible enough for your control cabinet layout?") and initial performance (e.g., "Has the cable reduced wiring complexity compared to your previous solution?").
Warranty Claim Debriefs: After resolving a warranty claim, the after-sales team conducts a brief debrief with the customer to understand the root cause of the issue (e.g., "Do you believe the sheath damage was due to environmental factors?") and evaluate the resolution process (e.g., "Was the replacement cable delivered in a timely manner?").
Annual Customer Advisory Panels: For key customers (e.g., large automation integrators, manufacturing plants with ongoing projects), the manufacturer hosts annual advisory panels. These in-person or virtual meetings bring together customers, product developers, and technical experts to discuss long-term needs (e.g., "What cable features would support your future automation upgrades?") and emerging industry trends (e.g., compatibility with Industry 4.0 sensors).
All feedback is compiled into a centralized database and analyzed quarterly by a cross-functional improvement team, which includes representatives from product development, production, sales, and customer support. The team uses statistical analysis to identify trends—for example, if 30% of post-installation interviews mention difficulty stripping the sheath, this is flagged as a high-priority issue. Qualitative feedback (e.g., suggestions for more durable labeling) is categorized and prioritized based on alignment with customer needs and business goals.
Actionable improvements are implemented within defined timelines:
Product Design Improvements: If feedback highlights issues with the cable’s flexibility in cold environments, the product development team may reformulate the PVC sheath with additional plasticizers to improve low-temperature performance (e.g., reducing the minimum operating temperature from -15℃ to -25℃). This change is tested in environmental chambers and validated with sample shipments to key customers before full-scale production.
Production Process Adjustments: If quality control data from feedback shows inconsistencies in insulation thickness, the production team may upgrade the extrusion machines with real-time laser gauges that provide more precise thickness measurements. This adjustment reduces defect rates and ensures uniform performance across all cables.
Service Enhancements: If customers report delays in warranty claim approvals, the after-sales team may streamline the claim review process by implementing a digital portal where customers can upload photos, videos, and documents directly—reducing review time from 48 hours to 24 hours.
The manufacturer communicates improvements to customers through multiple channels:
Product Update Notifications: Customers who have purchased the cable receive email notifications when significant updates are made (e.g., a new sheath formulation, improved labeling). The notification includes details of the change, the problem it addresses, and how it benefits the customer.
Annual Sustainability and Improvement Report: This report summarizes the feedback collected over the year, the improvements implemented, and the impact of those improvements (e.g., "Sheath reformulation reduced cold-weather flexibility complaints by 40%").
Direct Follow-Ups: Customers who provided critical feedback (e.g., identifying a safety issue) receive personalized follow-ups to inform them of the actions taken and invite them to test the improved product (e.g., a sample of the cable with the new sheath).
This feedback-driven process not only enhances the quality of the 24-core & 12-core control cable combo but also builds long-term trust with customers. By demonstrating that their insights directly shape product and service improvements, the manufacturer fosters collaborative partnerships that extend beyond individual transactions.
