sf6 circuit breaker Vacuum Charging Safe and efficient

The sealed tank, rated IP65, contains the circuit breaker and three position disconnect switch. The equipment is insulated using SF6 gas. Sealed tanks isolate the primary live parts from contaminants and reduce maintenance requirements. Tanks are machine welded at the factory and sealed for life. Tanks do not require any on-site gas filling.

  • Comparison Between Vacuum and SF6 Circuit Breaker

    Aug 29, 2018For the vacuum-circuit breaker the service interval lies between 10,000 and 20,000 operations. For the SF6 designs the value varies between 5,000 and 20,000 whereby, the lower value applies to the puffer circuit-breaker for whose operation, the mechanism must deliver much more energy.
