The 2-core PVC insulated copper cable comes in a wide range of specifications, covering 1.5-6mm², which can accurately adapt to medium and low-load power demand in different scenarios, providing stable power transmission guarantee for various electrical systems.

The conductor of the 1.5mm² cable is stranded with multiple fine Copper Wires with a diameter of 0.15mm. Through a scientific stranding method, the overall cross-sectional area reaches 1.5mm². At room temperature, its DC resistance is ≤12.1Ω/km, and the low resistance value can reduce energy loss during current transmission. The allowable continuous current-carrying capacity of this specification cable is 16A, which is sufficient to meet the power supply needs of lighting fixtures and small household appliances (such as desk lamps, electric fans, rice cookers, etc.), making it an ideal choice for home lighting circuits and small appliance power supply lines.

The conductor of the 2.5mm² cable also adopts a multi-strand fine copper wire stranded structure with a cross-sectional area of 2.5mm². Its DC resistance at room temperature is ≤7.41Ω/km, and the current-carrying capacity is increased to 25A, which can easily cope with the power consumption of slightly larger household appliances such as air conditioners, electric water heaters, microwave ovens, etc. It is widely used in power supply lines in home kitchens, bathrooms and other areas.

The Stranded Copper Wires of the 4mm² Cable Conductor are thicker, with an overall cross-sectional area of 4mm², a DC resistance of ≤4.61Ω/km at room temperature, and a current-carrying capacity of 32A. This specification cable is suitable for control circuits of small industrial machinery, such as control lines of small lathes and milling machines, and can also be used for main lines of household appliances with larger power, such as branch lines of central air conditioners.

The 6mm² cable is a model with a relatively large current-carrying capacity in this series. Its conductor cross-sectional area is 6mm², the DC resistance at room temperature is ≤3.08Ω/km, and the current-carrying capacity reaches 42A, which can cope with power transmission of larger power equipment, such as power supply lines of small industrial air compressors, water pumps and other equipment, and can also be used as the main line of the home main circuit.

The rated voltage of this series of cables is 300/500V. This voltage level can not only meet the 220V standard voltage demand of homes and offices, but also effectively withstand the fluctuation of grid voltage, providing sufficient voltage margin for the safe operation of the circuit, and avoiding damage to the cable insulation layer due to sudden voltage rise.

In addition, the thickness of the insulation layer and sheath of cables with different specifications varies and increases with the increase of specifications. The 1.5mm² cable has an insulation thickness of 0.8mm and a sheath thickness of 0.6mm; the 2.5mm² cable has an insulation thickness of 0.9mm and a sheath thickness of 0.7mm; the 4mm² cable has an insulation thickness of 1.0mm and a sheath thickness of 0.7mm; the 6mm² cable has an insulation thickness of 1.0mm and a sheath thickness of 0.8mm. This design can ensure that cables of different specifications have good mechanical strength and insulation performance, and can work stably in various environments.

The outer diameter of the cable also varies with specifications. The outer diameter of the 1.5mm² cable is about 5.0mm, the 2.5mm² is about 6.0mm, the 4mm² is about 7.0mm, and the 6mm² is about 8.0mm. The small outer diameter makes it more flexible in the wiring process and can adapt to the installation needs of narrow spaces. At the same time, the long-term allowable operating temperature of this series of cables is 70℃, and in the case of short-circuit for a short time (no more than 5 seconds), the maximum temperature does not exceed 160℃, which can maintain stable performance under normal use and emergencies.

With its various specifications and excellent performance, the 2-core PVC insulated copper cable has a wide range of distinctive applications in many fields such as building electrical, household appliances, and industrial control.

In the field of building electrical, cables of different specifications perform their respective functions. 1.5-2.5mm² cables are often used in lighting circuits and socket connections. In family residences, the lighting fixture lines in living rooms, bedrooms, studies and other areas, as well as the ordinary socket lines on the walls, mostly use 1.5mm² or 2.5mm² cables. The 1.5mm² cable can meet the power demand of general lighting fixtures, and the 2.5mm² cable can cope with the situation where multiple small household appliances connected to the socket work at the same time. The 4-6mm² cable is suitable for home main circuits and small Power Lines, such as the main line from the main distribution box to each sub-area distribution box, or the line connecting central air conditioners, electric heating and other larger power equipment. In office buildings, shopping malls and other large buildings, 1.5-2.5mm² cables can be used for lighting and ordinary sockets in public areas, and 4-6mm² cables can be used for power supply of small power equipment, such as ventilation equipment and small elevators.

In terms of household appliances, this cable is an ideal choice for power connecting lines of many household appliances. The power lines of washing machines, refrigerators, air conditioners and other equipment often use 2.5-4mm² cables of this series. Its flexible design allows the lines to be adjusted flexibly during the movement or installation of the equipment, avoiding damage due to stiff lines. For example, when installing an air conditioner, it is necessary to connect the indoor unit and the outdoor unit. The Flexibility of the 2-core PVC insulated copper cable allows the line to easily pass through wall holes and air conditioning pipes, and during the operation of the equipment, it can adapt to slight vibrations to ensure stable power transmission.

In the industrial control field, 4-6mm² cables have important applications. In the assembly line of small factories, it can be used to connect control lines of sensors, small motors and other equipment. The assembly line equipment will produce slight vibrations during operation, and the cable can withstand such vibrations, ensuring stable transmission of control signals and normal operation of the assembly line. In some small processing workshops, control lines of small machine tools, drilling machines and other equipment can also use this series of cables. Its good insulation performance and flexible characteristics can adapt to the complex environment of the workshop and the frequent operation of the equipment.

In addition, in some temporary electricity scenarios, such as outdoor small activities, temporary lighting at construction sites and power supply for small tools, 1.5-4mm² 2-core PVC insulated Copper Cables can also play an important role. Its portability and flexibility make the construction and disassembly of temporary lines very convenient, and can quickly meet the temporary electricity demand.

In terms of material selection and style design, the 2-core PVC insulated copper cable is fully combined with its performance requirements and use scenarios, ensuring the excellent performance and convenient use of the cable.

In terms of materials, the conductor is made of high-purity electrolytic copper. High-purity electrolytic copper has excellent conductivity, which can effectively reduce energy loss during current transmission and improve power transmission efficiency. At the same time, electrolytic copper has good ductility and toughness. After stranding, it can form a soft and unbreakable conductor structure, providing a basic guarantee for the flexibility of the cable, so that the cable is not easy to be damaged when bent or folded.

Both the insulation layer and the sheath are made of polyvinyl chloride (PVC) material. PVC material has excellent insulation performance, with an insulation resistance of ≥100MΩ, which can effectively block current, prevent electric leakage accidents, and ensure electrical safety. At the same time, PVC material has good corrosion resistance, which can resist the erosion of moisture, dust and slight chemical substances in the daily environment, protect the internal conductor from damage, and prolong the service life of the cable. In addition, PVC material also has a certain mechanical strength, which can withstand a certain degree of external impact and friction, ensuring that the cable is not easy to be damaged during installation and use.

In terms of style, the cable has a 2-core structure. The two core conductors are insulated from each other and arranged in parallel, with a unified PVC Sheath wrapped around the outer layer. This structural design not only ensures electrical isolation between the two cores, prevents faults such as short circuits, but also enhances the structural stability of the cable as a whole, making the cable less prone to core wire displacement, wear and other problems during use.

The cable comes in a variety of colors, commonly including black, white, gray, etc. Cables of different colors can be used to distinguish different circuits and uses, which is convenient for construction personnel to identify during installation and maintenance. For example, Black Cables can be used for power lines, and white cables can be used for lighting lines. This color distinction helps reduce misoperations in construction and improve construction efficiency and safety.

The surface of the cable is smooth and flat, without burrs and protrusions, which not only facilitates passing through pipes and trunking during wiring, reduces friction resistance, avoids damage to the insulation layer and sheath, but also makes the cable look neat and beautiful. At the same time, the surface of the cable is printed with clear marks, including specification parameters (such as 1.5mm², 2.5mm², etc.), rated voltage (300/500V), certification marks (such as GB/T 5023.4 standard certification), manufacturer information and meter marks, etc. These marks are printed with wear-resistant printing technology, which can remain clearly distinguishable during long-term use, facilitating construction personnel to quickly identify and operate during cutting and installation.

The cable is packaged in rolls, with each roll length divided into 100 meters and 200 meters. The appropriate length can be selected according to the actual construction needs, reducing material waste and improving construction efficiency.

The production process of 2-core PVC insulated copper cable is rigorous and complex. Each link from raw material processing to finished product inspection is strictly controlled to ensure that the product quality meets relevant standards and requirements.

The first step is the processing of copper materials. High-purity electrolytic copper ingots are selected as raw materials, heated to a molten state, and made into copper rods through continuous casting process. During the casting process, parameters such as temperature and casting speed need to be accurately controlled to ensure the purity, diameter uniformity and surface quality of the copper rod, laying a good foundation for subsequent processing.

Next is the wire drawing process of the copper rod. The copper rod is drawn through a wire drawing machine, and using dies of different specifications, the copper rod is gradually drawn into fine copper wires with a diameter of 0.15mm. During the drawing process, the copper wire will generate a certain internal stress. In order to eliminate the internal stress and improve the flexibility and ductility of the copper wire, the drawn copper wire needs to be annealed. Annealing is carried out in a special annealing furnace. By controlling the heating temperature and holding time, the crystal structure of the copper wire is made more uniform and the performance is more stable.

Then is the stranding of copper wires. According to the requirements of cables of different specifications, multiple strands of fine copper wires are stranded according to a specific stranding method and pitch to form a conductor with the required cross-sectional area. The stranding process is the key to ensuring the flexibility of the cable. Reasonable design of stranding pitch and number of strands can make the conductor have good flexibility and fatigue resistance, ensuring that the cable can maintain good conductivity and structural integrity after repeated bending. During the stranding process, it is necessary to ensure that the tension of each strand of copper wire is uniform and arranged neatly to ensure the roundness of the conductor and the uniformity of conductivity.

After stranding, the conductor is subjected to insulation layer extrusion. PVC particles are added to the extruder and heated to melt into a melt. At the die head of the extruder, the molten PVC melt is evenly extruded and wrapped on the surface of the conductor through a die to form an insulation layer. During the extrusion process, it is necessary to accurately control the extrusion temperature, extrusion speed and die size to ensure that the insulation layer has uniform thickness, smooth surface, and is closely combined with the conductor without defects such as bubbles and impurities. Cables of different specifications have different insulation layer thicknesses, which need to be strictly controlled according to design requirements.

After the insulation layer extrusion is completed, the two cores are arranged in parallel and the sheath is extruded. The two core wires covered with insulation layers are placed in parallel and sent to another extruder together, and a unified PVC sheath is extruded outside them. The sheath extrusion process is similar to the insulation layer extrusion, and it is necessary to ensure that the sheath has uniform thickness, smooth surface, and is closely combined with the internal insulation layer to form a whole, enhancing the mechanical strength and protection performance of the cable.

The cable after sheath extrusion needs to be cooled, usually by water cooling. The cable is introduced into a cooling water tank, and through rapid cooling with cold water, the PVC sheath is quickly solidified and shaped to ensure the dimensional stability and performance stability of the cable. The cooled cable is tested by a spark tester, and by applying high voltage electricity, it is checked whether the insulation layer and sheath have defects such as pinholes and damage to ensure that the insulation performance of the cable meets the requirements.

Subsequently, the cable enters the traction and take-up process. The traction machine pulls the cable at a constant speed to ensure uniform tension of the cable and avoid the cable being stretched or damaged due to excessive tension. The take-up machine neatly winds the cable on the reel to form a 100-meter or 200-meter coiled product. During the take-up process, it is necessary to control the take-up speed and tension to ensure that the cable is arranged tightly and neatly on the reel, which is convenient for transportation, storage and use.

During the production process, sampling tests are also required for the cable, including multiple indicators such as DC resistance of the conductor, thickness of the insulation layer and sheath, voltage resistance performance, insulation resistance, flexibility, etc. Only cables that meet the standard requirements in all indicators can be delivered as finished products. At the same time, the production workshop must maintain cleanliness to avoid the impact of dust, impurities, etc. on product quality.

The packaging design of 2-core PVC insulated copper cable fully considers the needs of product protection, transportation, storage and use, ensuring that the cable remains in good condition during circulation.

The cable is packaged in rolls, with each roll length of 100 meters or 200 meters. The reel is usually made of hard paper or plastic, which has a certain strength and rigidity, can support the weight of the cable, and prevent deformation during transportation and storage. Paper reels have low cost and good environmental protection, and can be recycled; plastic reels have better moisture resistance and wear resistance, and are suitable for storage and transportation in humid environments.

When the cable is wound on the reel, mechanical winding is adopted to ensure that the cable is arranged neatly and tightly, avoiding mutual extrusion, winding and wear. After winding, a layer of transparent plastic film is 套在 the outside of the reel, which can play the role of moisture-proof, dust-proof and anti-pollution, protect the insulation layer and sheath of the cable from the influence of the external environment, and also prevent the cable from loosening and falling off the reel.

A detailed label will be pasted on the side or end face of the reel, which clearly indicates the product name, specification (such as 1.5mm², 2.5mm², etc.), rated voltage (300/500V), length, certification mark, manufacturer name, production date, batch number, etc. This information is convenient for users to check when receiving and accepting products, ensuring that the received products meet the order requirements.

For cables transported in batches, multiple reels will be neatly stacked on wooden pallets or strong cartons. Wooden pallets have strong bearing capacity, and are convenient for loading, unloading and handling with forklifts and other equipment, suitable for transportation of large quantities of products; cartons are suitable for transportation of small quantities of products, light and easy to stack. During stacking, partitions or buffer materials will be placed between the reels to reduce mutual collision and friction and further protect the products.

The selection of packaging materials focuses on environmental protection, and tries to use recyclable and degradable materials to reduce environmental pollution. At the same time, excessive packaging is avoided, and under the premise of ensuring product safety, packaging materials are saved and packaging costs are reduced.

The transportation process of 2-core PVC insulated copper cable must strictly abide by relevant regulations and operating procedures to ensure that the products are delivered to the destination safely and timely.

The transportation mode can be selected according to the transportation distance, quantity and customer needs. Road transport is usually used for short-distance transport or small batches of goods. Road transport has high flexibility, can realize door-to-door service, and has a fast transport speed, which is suitable for emergency orders. Railway transport can be selected for long-distance transport or large quantities of goods. Railway transport has relatively low cost, large transport volume, and is less affected by natural factors such as weather, and the transport process is stable. For exported products or large quantities of transport across regions, water transport can also be used. Water transport has low cost, but the transport time is relatively long.

Before transportation, the packaged cables need to be properly fixed. For cable reels stacked on pallets, strapping should be used to firmly fix them on the pallets to prevent shaking and dumping during transportation. For cables loaded in trucks or containers, the placement position should be reasonably arranged to avoid mutual extrusion, and ropes should be used to fix them to prevent displacement during transportation.

During transportation, effective protective measures must be taken to prevent the cables from being exposed to direct sunlight, rain, snow, and high-temperature baking. Prolonged direct sunlight and high temperatures can cause the temperature of the cable to rise, which may lead to aging of the PVC Insulation layer and sheath, affecting their performance and service life. Rain and snow can make the cable damp, reducing its insulation performance and increasing the risk of electric leakage. Therefore, when transporting, the transport vehicles or containers should be covered with waterproof and sunproof tarpaulins to protect the cables from harsh weather conditions.

It is also necessary to avoid contact between the cables and sharp objects, corrosive substances, etc., during transportation. Sharp objects may scratch the insulation layer and sheath of the cable, and corrosive substances may corrode the cable materials, leading to damage to the cable's performance. During loading and unloading, care should be taken to handle the cables gently, avoiding rough operations such as throwing and dropping, to prevent damage to the cable reels and the cables themselves.

Drivers should abide by traffic rules during transportation, maintain a safe driving speed, avoid sudden braking, sharp turns, and other behaviors that may cause the cables to shake violently, ensuring the stability of the goods during transportation. For long-distance transportation, regular inspections should be carried out on the way to check the fixing status of the cables and the integrity of the packaging. If any problems are found, they should be dealt with in a timely manner.

The shipping process of 2-core PVC insulated copper cables is designed to be efficient and standardized to ensure that products are delivered to customers accurately and on time.

If the required products are in stock, they will start the shipping preparation work immediately; if there is a shortage, they will notify the production department in a timely manner to arrange production, and the production department will formulate a production plan to ensure that the products are completed and delivered to the warehouse within the agreed time.

Before shipping, the warehouse staff will conduct a comprehensive inspection of the cables to be shipped. They will check whether the specifications, models, and quantities of the cables are consistent with the order, whether the packaging is intact, and whether the labels on the reels are clear and accurate. At the same time, random sampling inspections will be carried out on the appearance and performance of the cables to ensure that there are no quality problems such as insulation layer damage, conductor oxidation, etc. Only the cables that pass the inspection can be shipped.

The warehouse will then arrange the shipping mode according to the customer's requirements and the actual situation of the goods. For small quantities of goods or urgent orders, express delivery will be chosen, which has the advantages of fast speed and door-to-door service. For large quantities of goods, logistics transportation such as road or railway will be selected, which is more economical. When cooperating with logistics companies, the warehouse will sign a transportation agreement to clarify the rights and obligations of both parties, including the transportation time, loss compensation, etc.

After the goods are shipped, the sales department will promptly inform the customer of the shipping information, including the logistics company's name, waybill number, estimated arrival time, etc., so that the customer can track the logistics information in a timely manner. The sales staff will also pay attention to the logistics progress.
