NHBV cable is a fire-resistant PVC-insulated building wire. "NH" signifies fire resistance, "B" is for building wire, and "V" represents PVC insulation. The oxygen-free copper conductor offers excellent conductivity and low power loss. PVC insulation ensures moisture, acid-alkali resistance, and mechanical strength. Rated voltage: 450/750V, ideal for low-voltage power distribution. Designed as a single-core cable, conductor sizes range from 1.5mm² to 10mm². Key benefit: stable power during fires, perfect for fire protection systems, emergency lighting, critical devices, and indoor wiring with fire resistance needs. Complies with GB/T 5023-2008 and GB/T 19666-2019 for safety and reliability.
