  • SF6 Circuit Breaker

    The SF6 Circuit Breaker is a type of circuit breaker that uses Sulphur hexafluoride gas in order to quench the arc to protect the power distribution systems. This inert gas is colorless, odorless and non-flammable which provides high thermal conductivity. It acts as an insulator and consumes less voltage unlike other breakers…
