High voltage Short circuit ground wire introduction:
Short-circuit grounding wire is a safety device for grounding protection to be connected prior to maintenance of electrical equipments or lines powered off, which may avoid personal injury or equipment damage caused by accidental energization.
Usage of short-circuit grounding wire:
Used in electrical line and substation construction to prevent electrostatic induced electric shock caused by electrified body nearby or ensure safety in case of false switching.
（A-Used for copper bar and aluminum bar in switch cabinet）
Operating voltage class (KV)
Rated short-circuit current（KA/1S）
Cross section of matched short-circuit wire （mm2）
（B—Used for round wire for outdoor power transmission and transformation lines)
