BV Electrical Cable is a PVC-insulated pure copper cable designed specifically for fixed house wiring, with a rated voltage of 450/750V and cross-sectional areas ranging from 1.5mm² to 16mm². Supplied directly by the factory, it combines high cost-effectiveness with reliable performance. Its core is a single solid pure copper conductor with a purity of over 99.95%, which, after annealing, has excellent conductivity (conductivity ≥58MS/m) and mechanical strength, stably adapting to different power requirements: 1.5mm² is suitable for lighting circuits, 2.5mm² meets the power supply of ordinary sockets, 4mm² to 10mm² can carry high-power appliances such as air conditioners and electric water heaters, and 16mm² is applicable to household main lines or small commercial power distribution systems. The outer layer of the conductor is wrapped with a uniform PVC insulation layer, with thickness increasing from 0.6mm to 1.4mm according to specifications. The insulation resistance is ≥100MΩ, which can withstand a 2kV power frequency withstand voltage test, effectively isolating current and resisting daily wear. The PVC material complies with UL94 V-0 flame retardant standards, self-extinguishing within 30 seconds after the open flame is removed, and has an operating temperature range of -15℃ to 70℃, adapting to most indoor environments. The surface of the cable is printed with clear marks, including specifications, voltage level, certification marks (such as GB 5023, IEC 60227) and production information, facilitating construction identification and quality traceability. Various colors (red, blue, yellow, etc.) can distinguish phase lines and neutral lines, reducing the risk of wiring errors. As the main product for house wiring, the solid structure of BV cable makes it rigid, suitable for embedding in walls, threading through pipes or laying in trunking, and not easy to deform during long-term fixed installation. The factory direct supply model reduces intermediate links, ensuring price advantages while providing customized length services (such as 100m/roll, 200m/roll). The product has passed strict tests, including conductor resistance, insulation aging resistance, flame retardant performance, etc., ensuring stable and reliable performance in long-term residential use. It is an ideal choice for household wiring that balances safety, durability and economy.
