TGZ32-12 Casting Resin / Epoxy Resin Bushing , Busbar Wall Feed Through Bushing
GNo -12 indoor HV disconnector series are designed under requirement of AC HV Disconnecting Switch and Earthing Switch of GB1985-89.It is a main unit of switchgear system enclosed by metal armouring or other similar approaches. It can be applied to three-phase AC power system of rated voltage 12 kV & frequency 50Hz, especially for small-size switchgear to optimize inner structure and occupy less outer space.
