BVVB indicates that the cable is PVC insulated and PVC sheathed flat cable for fixed wiring. It is an indispensable basic building material in home decoration and an important part of concealed engineering.
BVVB indicates that the cable is PVC insulated and PVC sheathed flat cable for fixed wiring. It is an indispensable basic building material in home decoration and an important part of concealed engineering.
BVVB wires are made of oxygen-free copper conductors, which make the copper wires brighter in appearance and lower in resistance, while having excellent electrical conductivity and high safety, the long-term operating temperature of the wires should not exceed 70°C to prevent the wires from heating up.
BVVB is mainly used in power transmission lines and control of mobile electrical appliances such as lifting equipment, cable tracks, transmission machinery, elevators, telescopic machinery and equipment in special places, and household lighting.
