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.

IntroductionTopics Covered by The Working GroupConclusionsSince the introduction of Gas Insulated Substations (GIS) in the late 1960s, sulphur hexafluoride (SF6) has become the favourite insulating and arc quenching medium thanks to its remarkable characteristics. However, SF6 has the major drawback of presenting a global warming potential (GWP) if released to the atmosphere, which is 23,500 times higher than CO2 and a lifetime in the atmosphere of around 3200 years according to IPCC Assessment Report 5 (AR5) from 2014. Due to these properties, it is one of th…See more on electra.cigre.orgEnd of life factors in high voltage gas insulated switchgear with … switchgearcontent/2020/07/06/1997/end of life factors in high voltage gas...2020/7/67 Gas quality: A first indicator for end of life of non SF6 gases and gas mixtures would be the gas lifetime statement of the equipment manufacturer.
