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 typeshttps://circuitglobe.com/wp-content/uploads/2016/06/sf6-circuit-breaker-888-compressor.jpg
