Product Description

Our factory

We are professional manufacturer of current transformer ,voltage transformer, Vacuum Circuit Breakers/Recloser,Isolation switches,Dropout Fuse Cut-out,Lightning Arresters,High and Low Voltage Cabinets,Metering Devices,Power Distribution Transformers  etc.

General

The "GW5-35" outdoor high voltage switch equipment of single phase AC 50Hz.The product is suitable for power systems with a rated voltage of 10kV to make or break power supply under circumstances of voltage and no load. The isolator is adopts isolated hook rod to operate.

Service conditions

1. The altitude does not exceed 1000m.
2. The ambient air temperature: Maximum:+40ºC; Minimum:-30ºC, Paramos:-40ºC
3. The wind pressure does not exceed 700Pa.(corresponding to 34m/s wind speed).
4. The earthquake intensity does not exceed 8 degrees.
5. The working situation hasn't frequent violent vibration.
6. 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.
7.Pollution-proof type isolator is applying to severe filthy conduction area;however,it shouldn't be any explosive matters and matters causing fire.
