    Indoor rotary high voltage isolation switch

    Outline

    TGN3O-12 series rotary indoor high voltage isolation switch is a new type of rotary touch knife type isolation switch. The main structure is to fix two groups of insulators and contacts on the top of the three-phase common underframe and the next two planes by rotating the touch knife. Thus, the switch is switched on and off.

    TGN30-12D series switches are based on TGN30-12 switches adding earthing poles, which can meet the needs of different power systems. This product is designed with tight, small volume, strong insulation ability, easy installation and adjustment. Its performance meets the requirements of GB1985-89 AC High Voltage Isolation Switch and Grounding Switch, and it is suitable for rated voltage 10KV AC 50Hz and below the indoor power system. It is used for dividing and closing circuit with voltage and no load. It can be used with high voltage switchgear or separately.
