GN30-12 3 Phase 12kv 630A Indoor High Voltage Isolating Disconnect Switch Factory

The GN30-12 indoor rotary high-voltage isolation switch is a new type of isolation switch with a rotating contact blade. The main structure is to fix two sets of insulators and contacts on the upper and lower planes of the three-phase common chassis, and to achieve the opening and closing of the switch by rotating the contact blade.
