SF6 Electrical Equipment device

Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for SF6, both domestically and internationally, is as an electrical insulator in high voltage equipment that transmits and distributes electricity. 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 customer load centers. Several factors affect SF6 emissions from electric power systems, such as the type and age o…See more on epa.govCN103792044A - Electrical equipment SF6 gas leak detecting ... electrical equipment SF6 gas leak detecting device is composed of a gas collecting groove, a flow guiding pipe, a gas collecting barrel and an SF6 gas quantitative and qualitative leak...
