Sulfur Hexafluoride Gas, SF6 Gas Manufacturer, Factory does sulfur hexafluoride behave like a liquid? Apr 28, 2017. So why does sulfur hexafluoride behave like a liquid? It all comes down to weight and density, or how close the molecules inside a substance are to each other. Sulfur hexafluoride is a particularly dense gas -- almost five times as dense as air. This just means that more of its ...
SF6 Gas Use in Electrical Applications - SF6· Sulphur hexafluoride (SF6) is a man-made gas comprising of one sulphur and six fluoride atoms. SF6 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 …
