General
Technical Parameter

GN30-12 indoor rotary high voltage disconnector is a new type with rotary knife. The main structural formula is to fix two sets of insulators and contacts on the upper and lower planes of the three- -phase common low frame, realizing the opening and closing of the switch by rotating the knife. GN3-12D switch adds a form of connecting knife on the basis of GN30-12 to meet the needs of different power systems. This product is compact in design, small in space, strong in insulation, easy to install and adjust. It meets the requirements of "AC high voltage isolating switch and earthing switch", and is applicable to indoor systems with rated voltage up to 10 KV AC 50 Hz and below. It can be used as opening and closing circuit when there is voltage and no load. It can be used with high voltage switchgear or can be used alone.
