china Disconnector Switch Gw9-12/24kv/630A Outdoor High Voltage Isolating Switch

Product Introduction

Gw9-12 Outdoor High Voltage Isolating Switch is used in the power system with a frequency of 50Hz and a rated voltage of 12kV, as a circuit breaker when there is voltage and no load.

 

Gw9-12 Outdoor High Voltage Isolating Switch is composed of base, pillar insulator, conductive part, safety hook and other parts. Each phase of the knife is composed of two conductive blades. There are compression springs on both sides of the blades. Adjusting the height of the springs can obtain the contact pressure required by the switch.
