BV H05V-U and H07V-U series wires and cables for house wiring are solid pure copper conductor PVC insulated products specially designed for residential and small building electrical systems. They cover common specifications such as 1.5mm², 2.5mm², 4mm², 6mm², and 10mm², and have become an ideal choice for indoor fixed wiring due to their high safety and stability.​ Both cables use solid electrolytic copper conductors with a purity of ≥99.95%. After annealing treatment, the conductivity is ≥58MS/m, ensuring efficient current transmission. Among them, H05V-U has a rated voltage of 300/500V, suitable for low-power circuits; H07V-U has a rated voltage of 450/750V, which can carry higher-power equipment. The current-carrying capacity of different specifications is suitable for various scenarios: 1.5mm² (16A) is used for lighting circuits, 2.5mm² (24A) is suitable for ordinary sockets, 4mm² (32A) and 6mm² (40A) can be connected to high-power appliances such as air conditioners and electric water heaters, and 10mm² (63A) is applicable to household main lines or branch power distribution.​ The insulation layer is made of temperature-resistant PVC material. H05V-U has an operating temperature range of -15℃ to 70℃, and H07V-U can withstand an environment of -25℃ to 80℃. Both have passed UL94 V-0 flame retardant certification and can self-extinguish within 30 seconds after the open flame is removed. The insulation thickness increases from 0.7mm to 1.4mm according to specifications, with an insulation resistance of ≥100MΩ, which can withstand a 2kV power frequency withstand voltage test, effectively isolating current and resisting daily wear. The surface is printed with clear marks, including specifications, voltage level, CE certification (H05V-U/H07V-U), GB 5023 standard, and production information, facilitating construction identification and quality traceability.​ The cables come in various colors (red, blue, yellow-green, etc.), which can distinguish phase lines, neutral lines, and ground lines, reducing the risk of wiring errors. The solid structure has strong rigidity, suitable for fixed installations such as wall embedding and pipe threading, providing long-term stable power support for house electrical systems. It is a preferred wiring solution that balances safety, durability, and economy.
