[email protected]20/3/2013An Sulfr hexafluoride circuit breaker is a type of circuit breaker in which sulphur hexafluoride gas or SF 6 gas is used as the arc quinching medium, known as an Sulfr hexafluoride circuit breaker. SF 6 gas has excellent insulating property and it has a high electronegativity. Due to high electronegativity, it has a high affinity for absorbing free electrons.

Get PriceOverviewSynthesis and reactionsApplicationsGreenhouse gasPhysiological effects and precautionsSee alsoFurther readingExternal linksSulfur hexafluoride (gaz 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 sol
