Maintenance Of sf6 gas Gas Circuit Breakers | CsanyiGroup

May 05, 2010 · The heaters for gaz sf6 in circuit breakers are required to keep the gas from liquefying because, as the gas liquifies, the pressure drops, lowering the dielectric strength. The exact dielectric strength, as compared to air, varies with electrical configuration, electrode spacing, and electrode configuration.. Arc quenching – gaz sf6 is approxi­mately 100 times more effective than air in quenching spurious arcing. gaz sf6 also has a high thermal heat capacity that can absorb the energy of the arc
