Overview
Description:

HGW58-12/S630 type outdoor column three-phase linkage isolation switch (hereinafter referred to as isolation switch) adopts three-phase linkage structure.

There are mainly a chassis, an isolating blade, and a passing spring mechanism, and the isolating blade is fixed on the chassis through an insulator. The isolation knife and the tie rod insulator are interlocked, and the opening is realized under the force of the passing spring mechanism.

Use:

The switch is suitable for 12kV high-voltage transmission and distribution lines, used to open and close the three-phase circuit without load and voltage, and has obvious isolation fracture.
