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 is st…See more on en.wikipedia.orgEstimated Reading Time: 12 minsMissing:toshibaMust include:toshibaChina 12kv Sulfur Hexafluoride Double Radiation Power Supply … lilyman.en.made in china/product/RwFtxfTGqAYd/China 12kv Sulfur...China 12kv Sulfur Hexafluoride Double Radiation Power Supply System Inflation Cabinet, Find details about China High Voltage Switch Cabinet, Power Switch Cabinet from 12kv Sulfur Hexafluoride Double Radiation Power Supply System Inflation Cabinet HC

SF6 can be prepared from the elements through exposure of S8 to F2. This was also the method used by the discoverers Henri Moissan and Paul Lebeau in 1901.
