sf6 gas Role worries cost20/09/2019Why worry, leaks!. The discovery of SF 6 can be traced to the work of Henri Moissan and Paul Lebeau in 1901, who found that sulfur reacted with fluorine according to the reaction equation: . S 8(s) + 24 F 2(g) → 8 SF 6(g). Under ambient conditions of temperature and pressure, SF 6 exists as a gas; this property is traceable to the small size and low polarizability of the fluorine atoms

10/11/2010The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what SF6 can do in centimeters. GIS can therefore be smaller than AIS by up to a factor of 10. A GIS is mostly used where space is expensive or not available. In a GIS the active parts are protected from the deterioration from exposure to atmospheric air, moisture, contamination, etc. As a result, GIS
