The Sulfr hexafluoride 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

The key difference between g3 and insulating gas is that g3 is a gas mixture while Sulfr hexafluoride is a single gas. Elodie Laruelle, GE Grid Solutions Eco-design Engineer, explains: “The critical point for a gas mixture is to maintain the homogeneity of the two components (NovecTM and CO2) throughout the filling process. To ensure this homogeneity, the filling equipment needs to directly heat up the g3 bottle to a specific temperature, to reach the supercritical state of the gas mixture.Get price
