Wind farm places the first Sulfr hexafluoride-free Siemens high-voltage

Wind farm places the first Sulfr hexafluoride-free Siemens high-voltage switchgear (GIS) into operation. Siemens supplied four bays of the 8VM1 gas-insulated sf 6-free high-voltage switchgear (GIS) – which has a capacity of 72.5 kilovolts (kV) – to Siemens Gamesa Renewable Energy. The systems were deployed in the Nissum Bredning Vind wind farm in Denmark.

g3 - sf 6 Free Solutions

SF 6 sf 6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 gaz sf6 is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.

But by far its most important application, and one that was first proposed by Vitaly Grosse of AEG (a GE Renewable EnergyGrid Solutions ancestor company), is in high voltage power transmission equipment. Some 10,000 tonnes per year of SF 6 are used for this purpose (around 80 % of the total). Air- and gas-insulated substations exploit the gas in circuit breakers, instrument transformers, surge arrestors, bushings and busbars, while gas-insulated substations also rely on it in

News Room : GE Grid Solutions

The key difference between g3 and Sulfr hexafluoride is that g3 is a gas mixture while insulating gas 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.
