GN30-12 Series Indoor Rotating Disconnector

The GN30-12 is a novel rotary-blade indoor high-voltage disconnector. Its primary structure features two sets of insulators and contacts fixed on the upper and lower planes of a common three-phase base frame.

The circuit is connected or disconnected by rotating the contact blade.

The GN30-12D variant incorporates an additional grounding blade based on the GN30-12 design, meeting diverse power system requirements. This product is compact, space-saving, highly insulated, and easy to install and adjust. It complies with the requirements of GB1985-89 "AC High-Voltage Disconnectors and Earthing Switches" and is suitable for indoor systems with rated voltages up to 12kV AC 50Hz, enabling circuit making and breaking under energized but no-load conditions.

It can be used both in conjunction with high-voltage switchgear or as a standalone unit.
