Alstom unveils worlds first high-voltage equipment designed

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

Mechanism of Formation of SF Decomposition Gas Products and

reaction of decomposition products with water and oxygen are shown in Fig. 2. It can be seen that the major products of the decomposition reaction are sulphur oxides, while others are fluoride compounds. The concentrations of decomposition products are directly dependent on spark conditions and energy. Figure 2. The formation of SF 6Get price
