  • 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 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. The new substation takes up only 30 percent of the originally used space, thus freeing up land for other city requirements and enhancing the

    To overcome this constraint, a parallel technology was developed, the Gas-Insulated Substation (GIS), using a gas, for example sulphur hexafluoride (SF 6), at high pressure. SF 6 has excellent dielectric properties and is used as the insulating medium between the phases and between the phases and earth. As a consequence, a GIS is much more compact.
