sf6 device for extra high Voltages

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 custo…See more on epa.govBreakdown Characteristics of Liquefied SF6 and CF4 dielectric breakdown properties of SF6–CF4 mixtures were investigated at different ratios of SF6, 0.01–1.6 MPa, and gas temperatures up to 3000 K.

  • SF6: Insulated switchgear for DC voltages up to 600 kV

    1982-8-1The development and testing of the main components of a metal clad SF6-insulated switch gear for dc voltages up to 600 kV are described. The technical requirements of the components were derived from the design of a switchgear arrangement. The switchgear was tested, proving that switching requirments were met.
