General description :

 

GW5 Series Outdoor AC isolation switch for the exchange of outdoor high-voltage electrical equipment 52Hz, rated voltage level has 40.5KV, 72.5KV and 126KV, for the HV voltage line is  opening and closing without load conditions, as well as being used for maintenance high voltage bus, circuit breakers and so on, also can be used to open or close a small capacitor or inductive current

 

 

The basic conditions of use isolation switch:

 

Altitude:≤3000mAmbient air temp.:upper limited +40oC,lower limited -25oCEathquake intensity ≤8°The ground have not fire,exposion danger,seriously nasty,chemical etch and serious shake
