Alstom unveils worlds first high-voltage equipment designed

Visit our media section and follow the link "Press contacts". At the 2015 Hanover Fair, Alstom is presenting two first high-voltage applications using g 3 (green gas for grid), a gas mixture that can replace SF 6 for high voltage air-insulated (AIS) or gas-insulated switchgear (GIS) applications. SF 6 is a potent greenhouse gas commonly used as an electrical insulator.Get price
