GW1 Outdoor Isolation Switch

GW1series outdoor MV isolate switch is the high voltage switch equipment of composite structure, is suitable for outdoor 12kV line net with voltage and no load, to make opening and close. With CS□ type manpower operate machinery, can avoid earth line with power and composite flash-locks etc wrongoperate.
The operator is no need to put another earth line. Pollution-proof typeisolate switch satisfy customer in filthy conduction area. It can solve the pollution of shed when it is working.
