GW1-12G(D) series outdoor high voltage disconnect 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 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.
The altitude above sea level: 2000m
The ambient air temperature: -40℃~40℃ wind speed does not exceed 35m/s.
The earthquake intensity does not exceed 8 degrees.
The working situation is without frequent violent vibration.
The installation site of ordinary type isolator should be kept away from gas, smoke chemical deposition, salt-spray fog, dust and other explosive and corrosive maters that affect seriously insulation and conduction capability of the isolator.
Pollutioni-proof type isolator is applies to severe filthy conduction area, however, it shouldn’t be any explosive matters and matters causing fire
