  • Maintenance of SF6 Circuit Breaker - About Circuit

    Aug 14, 2019This 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.. The main problem with a SF6 circuit breaker is its
