Description
ISOLATOR SWITCH
The isolation switch is the high voltage switch equipment of single phase AC 50Hz. The product is suitable for power system switch on/off when system has voltage but no load.
The isolation switch adopts isolation hook rod to operate.

Application:
- The altitude shall be not more than 1000m
- The ambient temperature: -30degC ~+40degC ; Paramos: -40degC
- Wind pressue: <=700Pa (equals to 34m/s)
- Earthquake strength <=8degree
- Working place with no frequent vibration
- The installation site of ordinary type isolation switch should be kept away from gas, smoke, chemical deposition , salt-spray fog, dust and other explosive and corrosive items that seriously affect insulation and conductivity capacity of the isolator. The pollution-proof type isolator can be installed on the above polluted area but should be avoided from fire and explosion.
