Product Description
GN30-12(D) series Indoor high voltage disconnecting switches is a new type of touch rotating knife isolator , which special designed for XGN2-12 HV switchgear, with rated voltage 12kV and three phase AC 50Hz indoor device. It's mainly used for making and breaking circuit under with voltage and no load.
Its main structure in three-phase chassis of the upper and lower two plane, fixed two set of insulator and contact, by rotating contactor, so as to realize switching on & off.Environment condition
