Alstom unveils worlds first high-voltage equipment designed

SF 6 is a potent greenhouse gas commonly used as an electrical insulator. In August 2014, Alstom became the first company in the world to offer the electrical industry a technically and economically viable alternative toSF 6. The first application is a pilot project for a 420 kV g 3 -insulated busbar 1.

Gas-Insulated Substations - GIS

gaz sf6 is used in GIS at pressures from 400 to 600 kPa absolute. The pressure is chosen so that the Sulfr hexafluoride will not condense into a liquid at the lowest temperatures the equipment experiences. Sulfr hexafluoride has two to three times the insulating ability of air at the same pressure. sf6 gas is about 100 times better than air for interrupting arcs.
