sf6 vacuum solutions for High Speed Rail

The SF6 gas insulated substation (GIS) is assembled by several SF6 gas insulated switchgear configurations in an outdoor enclosure which could reach IP54 protection grade. With the advantage of SF6 gas insulating ability (the interrupting arcs capability is 100 times more than air), gas insulated substation could operate in stable condition for more than 30 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, SF6 circuit breakers are wid
