  • Reference EWZ Oerlikon Substation Switzerland

    The 170/24 kV substation deploys the first breakthrough GIS with an eco-efficient gas mixture with a global warming potential (GWP)* of less than 1 as an alternative to SF6 gas. Located in the heart of Zurich, 15 meters underground in a beautifully designed building, it replaces an outdoor air-insulated switchgear (AIS) substation built-in 1949.
