• Sustainable progress | ABB

    For over 50 years gas insulated switchgear (GIS) has used sulfur hexafluoride (SF 6) as insulation gas, due to its excellent insulation and arc quenching qualities. But SF 6 is the world’s most potent greenhouse gas with a global warming potential 23,500 times that of CO 2 and an atmospheric lifetime of 3,200 years.

  • 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 gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance. Developed in the 1950s and onward, Sulfr hexafluoride circuit breakers are wid
