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, …See more on en.wikipedia.orgEstimated Reading Time: 12 minsMissing:BrandMust include:BrandSF6 Gas Specialty Gases concordegasConcorde Specialty Gases, Inc. 36 Eaton Road.
