sf 6 Gas Use in Electrical Applications - Sulfr hexafluoride

Sep 03, 2018 · sensotec / September 3, 2018. Sulphur hexafluoride (SF 6) is a man-made gas comprising of one sulphur and six fluoride atoms. SF 6 gas is extremely chemically stable, non-flammable and highly electronegative, with an excellent dielectric property of approximately 2.5 times more than air. Therefore, it is commonly used in electrical switchgear, transformers and substations as an electrical insulation, arc quenching and cooling medium.
