what is an electrical High Voltage Safety Isola...

GW1series outdoor MV isolate switch is the high voltage switch equipment of composite structure,is suitable for outdoor 12kVline net with voltageand no load,to make opening and close.With type manpoweroperate machinery,can avoid earth linewith power andcomposite flash-locks etc wrongoperate
c The operatoris no need to put another earth line.Pollution-proof typeisolate switch satisfy customerin fithy conduction area.Itcansolvethe pollution of shed when it is working.

Product Details

Selection

Operating conditions

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 applicable to severe filthy conduction area

however, it shouldn't be any explosive matters and matters causing fire.
