Alstom unveils worlds first high-voltage equipment designed

At the 2015 Hanover Fair, Alstom is presenting two first high-voltage applications using g3 (green gas for grid), a gas mixture that can replace Sulfr hexafluoride for high voltage air-insulated (AIS) or gas-insulated switchgear (GIS) applications.Get price

gaz sf6 Gas-Insulated Switchgear - Blogger

The sf 6 GIS guarantees outstanding advantages for the planning and operation of high-voltage supplynetworks. For instance, the space requirement can be less than 10% of the space taken up by an equivalent conventional installation. As all live parts are metal enclosed and hermetically sealed, the insulating gas GIS is completely immune to atmospheric pollution (fog, sand, salt, etc.) and industrial pollution (dust, smoke, gas, etc.).Get price
