2013/3/20An SF6 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 SF6 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.

Environmental ConcernsSafety ConcernsSpecial Handling ProceduresInstallation ConcernsOperation and Maintenance ConcernsEnd of Life and Recycling ConcernsThe insulating gas used in MV GIS switchgear,sulfur hexaﬂuoride (SF6), is a highly potent greenhouse gas with a global warming potential 23,900 times greater than CO2. SF6 also has an atmospheric life of 3,200 years, so it will contribute to global warming for a very long time.
