Product Description

 

Introduction

The GN30-12 rotary indoor high-voltage isolating switch is a new type of isolating switch with a rotating contact type. The main structure is to fix two sets of insulators and contacts on the upper and lower planes of the three-phase common chassis. Rotate the contact knife to achieve the switching of the switch.

The GN30-12D type switch is based on the GN30-12 type switch with a grounded knife to meet the needs of different power systems. This product is compact in design, small in space, strong in insulation, easy to install and adjust. Its performance meets the requirements of GB1985-89 "AC high-voltage isolating switch and grounding switch". It is suitable for indoor voltage system with rated voltage of 10 kV AC 50Hz and below. As a split circuit in the case of voltage and no load. It can be used with high voltage switchgear or it can be used alone.
