SF6 gas Mixtures Load break switch equipment

May 30, 2019Although gas-insulated switchgear (GIS) is the obvious application for climate-friendly SF 6 alternative gases, it is not the only one. SF 6 can also be used in air-insulated switchgear (AIS), especially for components like circuit-breakers or switch-disconnectors, to be more precise.
