  • SF6 Circuit Breakers - Construction, Types and Working

    SF6 is approximately 100 times more effective than air in quenching spurious arcing. SF6 also has a high thermal heat capacity that can absorb the energy of the arc without much of temperature rise. Electrical properties. The excellent dielectric properties of SF6 are due to the electronegative character of its molecules. It has a pronounced tendency to capture free electrons forming heavy ions with low mobility making the development of electron avalanches very difficult.

  • What is SF6 Circuit Breaker? Construction, Working Principle

    A circuit breaker in which SF 6 under pressure gas is used to extinguish the arc is called SF 6 circuit breaker. SF 6 (sulphur hexafluoride) gas has excellent dielectric, arc quenching, chemical and other physical properties which have proved its superiority over other arc quenching mediums such as oil or air. The SF 6 circuit breaker is mainly divided into three types.
