Bare copper Specifications: 162,535,507,590 square (mm) ① substation tail clip Material: high-strength aluminum material (aluminum) ② line to nail Material: iron materials ③ Lever material: Epoxy high voltage ground wire in accordance with the voltage level can be divided into: 10KV ground wire, 35KV high-voltage ground wire, 110KV grounding line, 220KV high-voltage ground wire, 500KV high voltage grounding pole long 10KV-1m 35KV-1.5m purposes: for line and substation construction, in order to prevent the charged body near electrostatic induction to ensure the safety of the use or misuse of electric shock when closing. (When the high-pressure equipment outage maintenance or other work equipment grounding wire prevents sudden call to prevent the device near high-voltage electric voltage is induced harm to human body, can be used to power equipment exhausted residual charge.)
