Product Description

The GN30-12 indoor rotary high-voltage isolation switch is a 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 chassis. By rotating the contact knife, the switch can be opened and closed.
The GN30-12D indoor rotary high-voltage isolation switch is an additional form with a knife on top of the GN30-12 indoor rotary high-voltage isolation 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", and is suitable for indoor systems with a rated voltage of 10 kV AC 50Hz or below. It is used for opening and closing circuits under voltage and no load conditions. It can be used together with high-voltage switchgear or separately.
