  • sf 6 Circuit Breaker Types, Working Principles Maintenance.

    Feb 20, 2021 · In a high-voltage circuit breaker like sf6 gas, current interruption is achieved by separating the contacts in a gas medium. The sf6 comprises both fixed and movable contacts enclosed in a gas system at a pressure of around 2.8 kg/cm 2. Whenever a fault arises, the movable contacts separate, and an arc strikes in between them.
