The vast majority of countries or industries have clear standard regulations for the wires and cables we produce now, with the main purpose of ensuring uniform design and use. I will mainly introduce several wire and cable standard codes related to the products produced by our company.

1) GB 5023-1997 Polyvinyl chloride insulated cables with rated voltage of 450/750V and below

2) JB 8734-1998 PVC insulated cables, wires and flexible cords with rated voltage of 450/750V and below

2) GB 5013-1997 Rubber Insulated Cables with Rated Voltage of 450/750V and Below

3) GB/T 12706-2002 Extruded Insulated Power Cables and Accessories with Rated Voltage from 1kV to 35kV

4) GB/T 9330-1988 Plastic Insulated Control Cables
