Since the 1950's, the U.S. electric power industry has used SF6in circuit breakers, gas-insulated substations and other switchgear used in the transmission system to manage the high voltages carried between generating stations and custo…See more on epa.gov V I E W REVIEW ELECTRICAL BREAKDOWNSF6 has a very high attachment cross section at low energies of 0 to X 0.4 eV. Thus a modest amount of added SF6 could attach almost all of the low energy electrons causing an appreciable increase ...[email protected]

Sulfur hexafluoride (SF6), which is the preferred gas for use in gas-insulated switchgear (circuit breakers, disconnect switches, etc. for high-voltage electrical circuits), has a very high globalGet Price
1997-7-26SF6 gas is an inert gas with dielectric strength and arc-extinguishing qualities. In SF6 breakers, the rate of rise of dielectric strength is very high and the time constant is very small. This provides another type of oil-less circuit breaker. However, the life of the contacts is short when compared to that of the vacuumGet Price
