  • SF6 Circuit Breaker Types, Working Principles Maintenance.

    2021-2-20SF6 circuit breaker is an extinguisher that uses sulfur hexafluoride gas to cool and quench the arc. It is the type of circuit breaker used to protect electrical grids, power stations, and distribution systems.. Sulfur hexafluoride gas has strong electronegativity and insulating properties, making them a better option than air and oil circuit breakers.

  • What is SF6 Circuit Breaker? Construction, Working

    A circuit breaker in which SF6 under pressure gas is used to extinguish the arc is called SF6 circuit breaker. SF6 (sulphur hexafluoride) gas has excellent dielectric, arc quenching, chemical and other physical properties and has proved its superiority over other arc quenching mediums such as oil or air. The SF6

    2016-2-17size of these kinds of circuit breakers makes them three times as expensive as modern SF 6 circuit breakers. Using other alternatives, such as nitrogen or carbon, or simply vacuum interrupters, would cost today twice as much to obtain the same performance as circuit breakers made with SF 6, especially at 72.5 kV and up.
