AC 12KV outdoor disconnect switch Outdoor High-voltage Isolator Switch GW5
Specifications
1. 12kv outdoor disconnect switch
2. Technical force is abundant,
3. detection equipment, and has many national patents.
GW5 type outdoor high-voltage disconnection switch is used in AC
three-phase outdoor high-voltage electric equipment with frequency
of 50Hz, applied for circuitry’s switching on or off in condition
with voltage but no load, electric disconnecting between electric
equipment under test(such as high voltage busbar, circuit
breaker)and charged high voltage circuitry, as well as switching on
or off of small capacitance or inductive current. When the switch
blade is in normal switching off powition, it can offer an
insulation spacing complying with the safety requirement. It is
widely used for35-220kV power substation.
