Product introduction 

Security earth wire is suitable for transmission lines,power plants and substation equipment,short circuit grounding for power outage maintenance.
The complete set of security earth wire consists of insulated operating rod with conductive clip, grounding flexible copper wire with transparent sheath, grounding pin or grounding clip.
The conductive clamp is divided into: double spring conductive clamp and circular spiral conductive clamp used to clamp the conductor, and flat spiral conductive clamp used to clamp the busbar.
1.Wire clamper with aluminum alloy casting,high strength,good conductivity.
2.The portable short-circuit grounding wire is packed in canvas bag with exported wooden boxes,which is easy to carry and transport.
matters needing attention:
1. First check whether the line is live and confirm that there is no power.
2. Connect the grounding terminal first and then the conductor terminal. The sequence of removing the grounding wire should be reverse;
3. Insulating gloves shall be used for assembling and disassembling grounding wires. Human body shall not touch grounding wires or terminated wires to prevent inductive conduction.
