Long Service Life Copper Contact Wire Soft Corrosion Resistant
Copper contact wire is an electrical conductor primarily composed of copper, designed to facilitate the flow of electric current. It is typically cylindrical in shape and comes in different lengths and diameters to suit various applications.
There are several advantages of using copper contact wire in power transmission and distribution systems:
The following are some applications of copper contact wire
