Description

GN30-12 rotary indoor high voltage disconnecting switch is a new type of disconnecting switch with rotating contact knife. Its main structure is to fix two groups of insulators and contacts on the upper and lower planes of the three-phase common base frame and rotate the contact knife to realize the opening and closing of the switch.

GN30-12D switch is based on GN30-12 switch to increase the form with grounding knife, can meet the needs of different power systems.

This product design compact, occupies the space small, the insulation ability is strong, easy to install adjustment, its performance conforms to GB1985-89 "alternating current high voltage isolation switch and the ground switch" the request, is suitable for the rated voltage 10kV alternating current 50Hz and below in the indoor system, as in has the voltage not to have the load condition, divides the use which the circuit. It can be used together with high voltage switchgear or independently.
