GW1-12D series outdoor high voltage 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 manpoewer operate machinary, can avoid earth life with power and composite flash-locks etc wrong operate, the operator is no need to put anther earth line. Pollution proof type isolate switch satisfy customer in filthy conductio area. It can solve the pollution of shed when it is work.
