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.
