railway sf6 gas Gas tank explain
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 circuit breaker is mainly divided into three types
