The GN30-12 rotary indoor high-voltage isolation switch is a new type of rotary contact knife type isolation switch. Its main structure is to fix two sets of insulators and contacts on the upper and lower planes of the three-phase common base frame. By rotating the contact knife, the switch can be opened and closed.
The GN30-12D switch is an additional form with a grounding knife on top of the GN30-12 switch, which can meet the needs of different power systems. This product has a compact design, small footprint, strong insulation capacity, and is easy to install and adjust. Its performance meets the requirements of GB1985-89 AC High Voltage Isolation and Grounding Switches. It is suitable for indoor systems with a rated voltage of 12kV AC 50Hz and below, and is used for opening and closing circuits under voltage and no load conditions. It can be used in conjunction with high-voltage switchgear or separately.
