GN30-12D Series Indoor Rotary High Voltage Isolating Switch

Overview

GN30-12 indoor rotary high-voltage isolating switch is a new type of isolating switch of rotary contact blade type. The main structure is to fix two groups of insulators and contacts on the upper and lower planes of the three-phase common chassis. Rotate the contact knife to realize the opening and closing of the switch.

GN30-12D indoor rotary high-voltage isolation switch is the addition of a knife on the basis of GN30-12 indoor rotary high-voltage isolation switch, which can meet the needs of different power systems. This product is compact in design, small in space, strong in insulation, and easy to install and adjust. Its performance meets the requirements of GB1985-89 "AC High Voltage Isolating Switches and Earthing Switches". It is used for opening and closing circuits under the condition of voltage and no load. It can be used together with high voltage switchgear or alone.
