SF6-alternative gases INSULATED SWITCHGEAR factory-sell-directly

Located 15 m underground, the GIS substation replaces an outdoor air-insulated switchgear substation built in 1949, freeing up about 70 % of the space occupied by the old substation. For decades, SF6 gas has been used extensively in the electrical industry for dielectric insulation and current interruption due to its physical properties.

  • SF6-alternative gases for application in gas-insulated

    Mar 20, 2018The environmental problems caused by greenhouse gases have received unprecedented attention. Sulfur hexafluoride (SF 6), 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 global warming potential, and there is a large international effort to find alternative gases.

    At the 2015 Hanover Fair, Alstom is presenting two first high-voltage applications using g 3 (green gas for grid), a gas mixture that can replace SF 6 for high voltage air-insulated (AIS) or gas-insulated switchgear (GIS) applications. SF 6 is a potent greenhouse gas commonly used as an electrical insulator. In August 2014, Alstom became the first company in the world to offer the electrical
