Product Detail

Model No.: GW38-252

High Voltage Outdoor Isolator Disconnector Switch 252KV

Main Description:

High Voltage Outdoor Isolator Disconnector Switch 252KV

Main Description:

GW38-40.5~252/630~4000 Type Disconnector Switch is good for reducing the distance and station arranging, especially for outdoor station.

Because of electric rod's self-rotation and switching structure and having self-locking function, it has strong property of motor performance resistance. Meanwhile, it can resist motor, wind pressure, earthquake and other outside power.

Technical Parameter:

1. 252kv voltage disconnector

2. We have 20 years exprience

3. Best price & Best quality
