Earth Wire Safety Grounding Rod

Customized Earth Wire Safety Grounding Rod made by Ningbo Lingkai Manufacture, all the copper wire is from the China standard authorized plant raw material.

 

To buy the earth wire safety grounding rod from us, we need to know the rod length, the section, the voltage operation site, and the copper wire length, and we can also customize the open grounding end clip size.

 

Our earth wire safety grounding rod possesses an arc opening. It is desirable for electric transmission lines. The available length of ground bar includes 1m, 2m, 3m, and 4m. Thus, it should be clearly written in the contract. The short-circuit earth wire and grounding pole (grounding end clip) are ordered additionally.
