With flexible specification coverage, stable electrical performance, and wide environmental adaptability, it has become a practical choice in low-voltage power distribution systems.​ In terms of specifications, the cross-sectional area of the wire ranges from 2.5mm² to 16mm², corresponding to different current-carrying requirements: 2.5mm² has a current-carrying capacity of approximately 25A, suitable for household lighting, socket circuits, and power supply for small appliances; 4mm² can carry up to 32A, meeting the needs of air conditioners, electric water heaters, and other medium-sized appliances; 6mm² has a current-carrying capacity of about 40A, applicable to small industrial motors and local power lines; 10mm² and 16mm² have current-carrying capacities of 60A and 80A respectively, mostly used for branch lines of industrial distribution boxes and power leads of large equipment. Its rated voltage is 450/750V, which is compatible with both 220V single-phase household circuits and 380V three-phase low-voltage industrial systems, adapting to various power distribution scenarios.​ In terms of materials and performance, the conductor is made of high-purity electrolytic copper (purity ≥99.95%) with excellent conductivity and low resistance (2.5mm² has a resistance of ≤7.41Ω per kilometer, 16mm² ≤1.15Ω), which can reduce transmission loss. The insulation layer is made of weather-resistant PVC material, with good insulation resistance (≥100MΩ·km) and temperature resistance (-15℃ to 70℃). It can resist humid environments in households (such as kitchens and bathrooms) and dust, slight oil pollution in industrial places. Meanwhile, it passes the flame retardancy test (complying with GB/T 18380 standard), delaying the spread of fire when exposed to fire.​ Its characteristic applications cover both household and industrial fields: in household scenarios, 2.5mm² and 4mm² wires are the main force in decoration wiring, used for wall embedding, ceiling pipe threading, connecting lighting, sockets, and various household appliances. The flexibility of PVC insulation facilitates bending and pipe threading, reducing construction difficulty; in industrial scenarios, 6mm² and larger specifications are often used for workshop power lines, assembly line equipment power supply, temporary construction cables, etc. They can withstand frequent movement and mechanical collisions, adapting to the power needs of machine tools, fans, water pumps, and other equipment. In addition, the wire can also be used for power supply of lighting and irrigation equipment in agricultural greenhouses, and public lighting systems in commercial places.​ In terms of installation and maintenance, the surface of the PVC insulation layer is smooth, with low frictional resistance when threading through pipes, and has excellent aging resistance, with a normal service life of more than 15 years. It is available in single-core or multi-core structures: single-core wires are suitable for fixed wiring, and multi-core flexible wires are convenient for connecting mobile equipment, meeting different installation needs. No special tools are required during construction, and wiring can be completed with conventional wire stripping and crimping. Later maintenance only needs to regularly check the integrity of the insulation layer, reducing long-term use costs.​ In summary, this PVC insulated copper wire provides a safe, economical, and easy-to-operate solution for household daily electricity use and industrial low-voltage power distribution with its precise specification classification, reliable material combination, and dual-scenario adaptability, balancing practicality and cost-effectiveness.
