Description:
FGW9-12 high-voltage load isolating switch is a high-performance isolating switch developed by our company to absorb foreign advanced technology. It has the advantages of reliable contact, large flow capacity and certain arc-proof capability.
For the power system with rated voltage of 10kV, as the voltage is connected and isolated, the isolated switch must be operated with a special hand-held load breaking device under load, so as to avoid casualties and Equipment damage.
The product developed by our company can be divided into resin pillar type and composite pillar type. Among them, the composite pillar type has better anti-pollution ability and no-cleaning property, which is the first recommendation.
Use environment:
1. The plain type elevation does not exceed 2000m; the high prototype elevation does not exceed 4000m;
2. Ambient air temperature: +40 ° C, -30 ° C;
3. The wind pressure does not exceed 700Pa (wind speed 34m/S);
4. The intensity of the earthquake does not exceed 8;
5. No frequent and severe vibrations;
6. There is no influence on the insulation performance of the switch, gas, chemical precipitation, salt spray, dust and other explosive and aggressive gases.
