  • MV Sulphur Hexafluoride Circuit-breakers for Outdoor

    2018-5-9installation use sulphur hexafluoride gas (SF6) to extinguish the electric arc and as the insulating medium. Breaking in SF6 gas takes place without current chopping or generation of overvoltages. These characteristics guarantee a long electrical life for the circuit-breaker and limited dynamic, di-electric and thermal stresses on the installation.

  • Sulfur Hexafluoride product services abb

    ABB achieved a significant breakthrough in switchgear technology with the development of a solution that deploys a new insulation gas medium as a substitute for sulfur hexafluoride (SF 6). This alternate gas mixture has similar insulation properties to SF 6 now used in gas-insulated switchgear, but with substantially lower environmental impact

    2018-5-10sulphur hexafluoride (SF 6) SF 6 is an inorganic chemical compound of the elements sulphur and fluorine. It is a non-toxic, colourless and odourless inert gas. As SF 6 is heavier than air it displaces the oxygen in the air if it is inadvertently set free. The dielectric strength of SF 6 is 2.5 times that of air.
