JN15-40.5/31.5 HV Earthing switch
Introduction:
JN15-12/31.5 high-voltage grounding switch is a kind of plant design and development of new type of grounding
switch with the domestic level. Structure is assembled, the load performance of GB1985-89 "AC high voltage
disconnectors and earthing switches" and the requirements of IEC129. Power system which is suitable for
indoor 3-12KV three-phase AC 50HZ. It has the ability to protect switch equipment other electrical equipment is
not damaged off certain. Can be matched with various high voltage switch cabinet, as high voltage electrical
equipment maintenance grounding protection.
Tthe use of environmental conditions
