3 Core 2.5mm² Flexible PVC Insulated Cable 300/500V is a multi-core cable widely used in low-voltage electrical systems, designed specifically for wiring scenarios requiring a certain degree of flexibility. Its core structure includes 3 conductors with a cross-sectional area of 2.5mm², each made of high-purity stranded copper. Stranded by multiple fine copper wires, it not only ensures excellent conductivity (conductivity ≥58MS/m) but also significantly enhances the flexibility of the cable, adapting to installation environments with frequent bending and folding, such as internal wiring of household appliances, office equipment connections, and small mechanical circuits.​ The cable has a rated voltage of 300/500V, suitable for low-voltage power distribution systems with AC 50Hz or 60Hz, and can safely carry a continuous current of approximately 24A (at an ambient temperature of 30℃), meeting the power requirements of most small and medium-sized electrical equipment. Each conductor is wrapped with a temperature-resistant and wear-resistant PVC insulation layer with a uniform thickness (about 0.8mm), which has good dielectric properties and can withstand a 2kV power frequency withstand voltage test, effectively preventing the risk of short circuits between core wires. At the same time, the PVC material has flame-retardant properties (complying with UL94 V-0 standards), which can self-extinguish quickly after the open flame is removed, reducing the risk of fire spread.​ The overall design of the cable focuses on practicality and safety: the 3 insulated core wires are arranged in parallel or twisted, and wrapped with a unified PVC sheath. The sheath is mostly gray or black, which not only enhances the overall structural strength but also resists external mechanical impact, moisture, and chemical corrosion. In addition, the core wires are identified by different colors (such as brown, blue, yellow-green), which is convenient for distinguishing phase wires, neutral wires, and ground wires during installation, in line with international electrical specifications, and reduces wiring errors.​ In terms of application scenarios, this cable, with its flexibility advantage, is widely used in power supply for mobile equipment (such as electric tools, stage lighting), concealed or exposed wiring in buildings, elevator trailing cables, internal connections of automation equipment, etc. Its operating temperature range is -15℃ to 70℃, which can adapt to most indoor and outdoor environments, and has passed multiple international and domestic standard certifications such as IEC 60227 and GB 5023, ensuring stable performance during long-term use.​ In conclusion, the 3 Core 2.5mm² Flexible PVC Insulated Cable, with its balanced conductivity, flexible installation characteristics, and reliable safety performance, has become an ideal choice for connecting small and medium-sized equipment in low-voltage electrical systems, meeting the dual needs of practicality and safety.

The Copper Core Power Cable, categorized under the RVV (Rubber-Vinyl-Vinyl) standard with 5, 6, 7, or 8 cores and conductor cross-sections of 0.75mm², 1.5mm², or 2.5mm², is a highly flexible, PVC-insulated and sheathed electrical cable engineered for low-voltage power transmission and signal integration in residential, commercial, and light industrial electrical installations. Its defining features—multiple cores, soft PVC/CU (copper) construction, and exceptional flexibility—address the growing demand for compact, multi-functional wiring solutions that can adapt to dynamic installation environments, from tight wall cavities in homes to movable equipment in workshops. This cable combines reliable electrical performance, mechanical durability, and cost-effectiveness, making it a staple for applications requiring simultaneous power supply and signal transmission, such as smart home systems, industrial control panels, and commercial lighting networks. At the heart of this cable’s design is its multi-core configuration (5–8 cores), a key advantage over single or 2–4 core cables. Each core consists of stranded copper conductors (class 5 flexibility per IEC 60228), with the number of strands tailored to the conductor size: 0.75mm² cores use 16 strands of 0.24mm diameter copper, 1.5mm² cores feature 49 strands of 0.20mm diameter, and 2.5mm² cores utilize 98 strands of 0.18mm diameter. This stranded structure delivers two critical benefits: first, it enhances the cable’s flexibility, allowing it to bend repeatedly (minimum bend radius of 4× the cable’s outer diameter) without conductor breakage—essential for installations involving movable equipment (e.g., office projectors, industrial conveyors) or routing through irregular paths (e.g., around door frames, inside furniture). Second, the high-purity copper (99.95% electrolytic grade) ensures excellent electrical conductivity: 0.75mm² cores have a DC resistance of ≤0.026Ω/m at 20°C, 1.5mm² cores ≤0.013Ω/m, and 2.5mm² cores ≤0.0078Ω/m, minimizing energy loss (I²R losses) even in long cable runs (up to 30 meters for 0.75mm², 50 meters for 2.5mm²). The PVC/CU soft sheath is another hallmark of this RVV cable, balancing protection and flexibility. The inner insulation of each core is made from soft PVC (Shore A hardness 60–70), which adheres tightly to the stranded conductors to prevent moisture ingress and electrical leakage, while maintaining pliability for easy stripping during termination. The outer sheath—also constructed from flame-retardant soft PVC (Shore A hardness 55–65)—adds a robust barrier against mechanical abrasion, chemical exposure (e.g., household cleaners, mild oils), and UV radiation (for indoor/outdoor transitional installations like patio lighting). This dual PVC layer complies with IEC 60332-1 (flame propagation) and IEC 60754-2 (halogen emission) standards: in the event of a fire, the sheath self-extinguishes within 10 seconds of flame removal and emits low levels of smoke (peak density ≤50% per IEC 61034), ensuring safety in occupied spaces such as homes, offices, and schools. Electrical performance is calibrated to meet global low-voltage standards, with a rated voltage of 300/500V—suitable for powering 110V/220V residential appliances, 230V commercial equipment, and 48V industrial control systems. The multi-core design enables simultaneous power and signal transmission: for example, an 8-core 1.5mm² RVV cable can supply power to a smart home hub (via 2 cores) while transmitting data to connected devices (e.g., thermostats, security cameras) through the remaining 6 cores, eliminating the need for separate power and data cables and reducing installation complexity. Current-carrying capacity varies by core size and application: 0.75mm² cores support 6–8A (ideal for low-power devices like LED strips, doorbells), 1.5mm² cores handle 10–13A (suitable for laptops, small air conditioners), and 2.5mm² cores carry 16–20A (for heavy-duty equipment like electric drills, commercial printers). Practical applications of this RVV cable span diverse sectors, leveraging its flexibility and multi-core functionality. In residential settings, 5–6 core 0.75/1.5mm² variants are used for smart home wiring—powering and connecting smart switches, motion sensors, and voice assistants, with the extra cores reserved for future expansions (e.g., adding new devices). The soft sheath allows the cable to be routed under carpets, behind baseboards, or through narrow wall cavities without damaging walls or the cable itself. In commercial buildings, 7–8 core 1.5/2.5mm² cables are deployed in office lighting networks and retail display systems: for instance, an 8-core 2.5mm² cable can power a row of retail LED lights (via 4 cores) and control their brightness/color (via the other 4 cores), streamlining wiring and reducing maintenance needs. In light industrial environments, 6–8 core 2.5mm² cables are used for movable equipment (e.g., assembly line tools, portable pumps), where their flexibility withstands frequent movement and their flame-retardant sheath protects against oil spills and mechanical impacts. Compliance with international standards ensures the cable’s reliability and compatibility across global markets. It meets IEC 60227 (PVC Insulated Cables for Fixed and Flexible Wiring), GB/T 5023 (Chinese Standard for PVC Insulated Wires and Cables), and UL 62 (North American Standard for Flexible Cables). Rigorous production testing—including voltage withstand tests (1.5kV for 5 minutes, no breakdown), insulation resistance tests (≥100MΩ at 500V DC), and flexibility tests (10,000 bending cycles with no conductor damage)—validates its performance. Additionally, the cable is RoHS-compliant, containing no hazardous substances (e.g., lead, cadmium), making it suitable for eco-friendly building projects. In summary, the Copper Core Power Cable (5/6/7/8 Core RVV 0.75/1.5/2.5mm PVC/CU Soft Sheath) stands out as a versatile, reliable solution for modern electrical installations. Its multi-core design enables integrated power and signal transmission, its soft PVC/CU construction ensures flexibility and durability, and its compliance with global standards guarantees safety and compatibility. As the demand for compact, multi-functional wiring grows—driven by smart home adoption, industrial automation, and space-efficient building design—this RVV cable remains a critical component, simplifying installations, reducing costs, and ensuring long-term performance in diverse environments.
