Operating PrincipleBrief HistoryDesign FeaturesGenerator Circuit BreakersHigh Power TestingIssues Related to SF6 Circuit BreakersComparison with Other TypesCurrent interruption in a high voltage circuit breaker is obtained by separating two contacts in a medium, such as sulfur hexafluoride (SF6), having excellent dielectricand arc quenching properties. After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity. SF6 gas is electronegativeand has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high pressure flow of sulfur hexafluoride gas, and an arc i…See more on en.wikipedia.orgEstimated Reading Time: 12 minsPeople also search forsulfur hexafluoride circuit breakersulfur hexafluoride melting pointsulfur hexafluoride usessf6 circuit breakersulfur hexafluoride dielectricsulfur hexafluorideSF6 properties, and use in MV and HV switchgear studiecd.dk/cahiers_techniques/SF6_properties.pdfPDF fileCahier Technique Schneider Electric nO. 188 / p.3 SF6 properties, and use in MV and HV switchgear Contents 1 Introduction 1.1 A brief history of use of SF6 p.4 1.2 SF6 manufacture p.5 1.3 Other uses of SF6 p.5 2 Physical and chemical properties of SF6 2.1 Physical properties p.6

Sulfur hexafluoride or sulphur hexafluoride, 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 soluble in water but quite soluble in nonpolar organic solvents. It has a density of
