OverviewSynthesis and reactionsApplicationsGreenhouse gasPhysiological effects and precautionsSee alsoFurther readingExternal linksSulfur hexafluoride (SF6) or sulphur hexafluoride (British spelling) is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non flammable, and non toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly solublein water but quite soluble in nonpolar organic solvents. I…

AbstractIntroductionTest SetupExperimental ResultsConclusionSulphur hexafluoride (SF6) gas and SF6 gas mixtures are widely used in gas insulated systems (GIS) because they have good dielectric and thermal properties. Among the various gas mixtures investigated so far, SF6 air, SF6 CO2, and SF6 N2 are most used gas mixtures. Also, these mixtures have much technical superiority in GIS. These are nontoxic and nonflammable gases, and they have less sensitivity to nonuniformities and higher liquefaction temperature at high pressure. GIS, switchgears, circuit b…See more on hindawiCited by: 1Publish Year: 2018Author: E.
