H07V-R PVC Insulated Building Wire: Structure, Manufacturing & Quality Standards
H07V-R is a classic building-wire type under CENELEC HD 21.3. "H" = Harmonized standard, "07" = rated voltage 450/750 V, "V" = PVC insulation, "R" = Class 2 stranded conductor. With oxygen-free copper conductor and PVC insulation, it is widely used in building distribution, switchgear secondary circuits and fixed equipment wiring. Simple structure, cost-effective, easy to install and reliable — one of the most widely used building wires worldwide.
