Product Description

 

 

         

GW4-11, 24, 35, 40.5, 72.5, 126 series outdoor AC high voltage isolating switch. It is suitable for power systems with a frequency of 50Hz and rated voltages of 11, 24, 35, 40.5, 72.5, and 126kv, and is used as a circuit breaker when the voltage is no load. Among them, the anti-pollution isolating switch can meet the requirements of users in heavily polluted areas, and can effectively solve the problem of pollution flashover in the operation of the isolating switch.
The isolating switch and the attached grounding switch are equipped with independent operating mechanisms. In order to ensure the correct operation sequence between the isolating switch and the grounding switch, this product is equipped with a mechanism interlocking device. The 35-110kV grounding switch is divided into Type 1 and I|, 15 and 220kV are type II, and the dynamic and thermal stability of type II earthing switch is the same as that of isolating switch.

 

Environmental conditions 
1. Altitude: 1000~ 3000m area
2. The ambient temperature is not higher than +40°C, and the minimum temperature is not lower than -35°C (not lower than -40-35°C in alpine regions).
3. The wind speed should not exceed 34m/s.
4. The seismic intensity shall not exceed 8 degrees.
5. The thickness of ice coating shall not exceed 10mm.
6. Anti-pollution products are suitable for heavily polluted areas.
7. Not suitable for places with flammable substances, explosion hazard, chemical corrosion and severe vibration.
