GN30-12 (D) Rotary Indoor High-Voltage Disconnector
GN30-12 rotary indoor high-voltage disconnector is a new type of rotary contact disconnector. Its main structure is to fix two groups of insulators and contacts on the upper and lower planes of the three-phase common chassis, and to achieve switch on by rotating the contact.

The GN30-12D switch is an additional form with grounding knife on the basis of the GN30-12 switch, which can meet the needs of different power systems. This product is compact in design, small in point space, strong in insulation capacity, and easy to install and adjust. Its performance meets the requirements of AC High Voltage Disconnectors and Grounding Switches (GB1985-89). It is applicable to indoor power systems with a rated power of 10kV AC 50Hz and below. It can be used for opening and closing circuits under voltage and no load. It can be used with high-voltage switchgear or used alone.
