12KV Outdoor Disconnect Switch Three Phases Isolating Switch
GW1-12 series outdoor high voltage isolate switch is the high voltage switch equipment of composite strudcture, is suitable for outdoor 12KV line net with voltageand no load, to make opening and close. With CS type manual operate machinery, can avoid earth line with power and composite flash-locks ets. wrong operate. The operator is no need to put another earth line. Pollution-proof type isolate switch satisfy customer in filthy conduction area. It can solve the pollution of shed when it is working.
