Chinese Standard Automotive Cables

QVR type copper core PVC insulated low-voltage wires for highway vehicles are mainly used in the electrical and instrument circuits of vehicles. The conductor of QVR is made of stranded bare copper or tin plated copper, and the insulation material is polyvinyl chloride (PVC). The rated temperature resistance range is -40 ° C to 70 ° C. In addition, QVR wires come in various colors, including standard colors and dual color combinations, and have flame retardant, oil resistant, RoHS environmental protection and other characteristics. The implementation standard is JB/T8139-1999.

Product Details

I. Product Description

Both QVR and QVR-105 are copper-core PVC-insulated low-voltage wires for road vehicles, specially designed for the internal electrical systems of automobiles. 2. QVR is suitable for conventional electrical appliances and instrument circuits in vehicles, with an operating temperature range of -40℃ to +70℃;

QVR-105 is optimized for electrical appliances and instrument circuits in high-temperature areas, featuring stronger heat resistance, with its operating temperature range extended to -40℃ to +105℃. Both use bare copper or tinned copper strands as conductors, covered with special cross-linked PVC insulation layers for automobiles, and comply with the environmental protection RoHS standards.

II. Implementation Standard

The product strictly complies with the JB/T 8139-1999 Standard for Low-Voltage Cables (Wires) for Road Vehicles.
