6 is used as insulation gas in gas-insulated switchgear (GIS) today since the technical performance of SF 6 perfectly matches to the technical requirements. The drawback of SF 6 is the high global warming potential (GWP) of about 23.500 (100 year time 2

Maintenance of SF6 Circuit Breaker - About Circuit

This breaker uses SF6 or sulfur hexafluoride as arc quenching or arc extinguisher medium. Although SF6 has very good dielectric property. But like minimum oil circuit breaker, the SF6 CB only utilizes the extinguishing property of the SF6 gas. Since, this page is about the maintenance of SF6 circuit breaker, let us go to the topic directly.
