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

  • Gas-Insulated Substations - GIS

    A gas-insulated substation (GIS) uses a superior dielectric gas, sf 6, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in sf6 gas gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what sf 6 can do in centimeters.
