Sulphur Hexafluoride Gas, Sulfr hexafluoride Gas - OVAC SWITCHGEAR

A typical Dew Point value for Tropical country like India, of - 37 0 C (180 PPMV) measured at atmospheric pressure is most satisfactory favoured for SF-6 breakers up to 400Kv range, since this value is to - 15.90C at breaker operating pressure of 7 Kg/cm2, which is well above lowest operating Temperatures in India. From this point of view, lowest acceptable Dew Point of - 300C (375 PPMV) can be fixed as a Danger Monitoring parameter, since it corresponds to - 80C Dew Point at 7 Kg./cm2Get price

Switchgear - Wikipedia

A switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.Get price
