1.GW5A 40.5kV Manufacturer Supplier Combined Electrical Appliances Hv Circuit Breaker Switch
GW5-35 series outdoor high voltage isolator is used for opening and closing circuit of 35KV outdoor power system under the condition of voltage and no-load. With fixed hook and self - locking device, with insulation hook rod effect operation. The pollution-proof type can effectively solve the flash caused by pollution during operation and meet the needs of users in polluted areas.
2.Conditions of Use:
1. Ambient temperature :-77℉~ + 104℉.
2. Height: less than 1000 meters.
3. Ambient humidity: monthly average relative humidity ≤90%, daily average relative humidity ≤95%.
4. Free from fire, explosion, serious pollution, chemical corrosion and violent vibration.
3.Main Features:
1) Scientific design and innovative structure.
2) The contact points are distributed on two planes, and the operating torque is small and the release pressure is small
And easy to adjust.
3) Improve the driving and conduction parts.
4) Column moving contact, can reduce the work intensity, ensure reliability
Conduction of the circuit.
