HOW TO MAINTAIN sf6 gas CIRCUIT BREAKER

gaz sf6 is a gaseous dielectric used in high voltage electrical equipment as an insulator or arc quenching medium. The separation of the CB contacts which are carrying current give rise to an arc. During arcing the circuit breaker maintains a relatively low pressure inside the chamber and there will be no danger of explosion and spilling of gas around.Get price
