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.
