  • Sulfur hexafluoride circuit breaker - Wikipedia

    Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay.Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit.Advantages over other media include lower operating noise and no emission

  • GIS Owners in California Must Comply With SF6 Regulation

    Jan 11, 2019Since the initial use of SF6 in the 1950s, SF6-containing circuit breakers, transformers, switches, fuses, and other equipment have been used regularly because SF6 is non-flammable, non-corrosive, non-toxic, and an effective arc suppressant, which allows SF6 equipment to have a small footprint and be relatively low maintenance.
