  • SF6 Gas and its Uses Within Electrical - SF6 Emissions

    Jul 11, 2014Sulphur hexafluoride (SF6) is a man-made gas comprising of one sulphur and six fluoride atoms. SF6 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…
