·Application
The"GW9-10G"type of outdoor high voltage isolator switch is thg high voltage switch equipment of single phase AC50Hz.The product is suitable for power system with rated voltage 10kV to break power supply under circumstances of with voltage and nomload.
The isolator is adopts isolated hook rod to operate.
·The normal conditions of use
· The altitude does not exceed 1000m.
· The ambient air temperature:Maximum+40°C;Minimum:General Area-30°C ,paramos-40°C .
· The wind pressure does not exceed 700Pa(corresponding to 34m/s wind speed).
· The earthquake intensity does not exceed 8 degrees.
· The working situation without frequent violent vibration.
· The installation site of ordinary type isolator should be away from gas,smoke chemical deposition,salt-spray fog,dust and other expiosive and corrosive materials that affect seriously insulation and conuction capability of the isolator.
· Pollution-proof type isolator is appl-es to severe filthy conduction area.however.It shouldn’t be any explosive matters and matters causing fire.
·Demension
The isolator can be installed verically or aslant,please see figture for overall and installation dimension
