Siemens supplies sf6 gas-free high-voltage switchgear for English

Siemens will supply 102 SF 6 -free, gas-insulated 8VM1 high-voltage switchgear (GIS) to Siemens Gamesa by the middle of next year. The switchgear will protect each wind turbine individually against overloads and short-circuits and make it possible to supply electricity reliably and without interruption. Developed for wind farms, the 8VM1 from the blue GIS portfolio operates with vacuum circuit-breaker technology and with clean air instead of sulfur hexafluoride (SF 6) as the insulating medium.Get price

Siemens develops sf 6-free gas-insulated medium-voltage switchgear

Switches and switchgear that use gaz sf6 as the insulating, switching, and extinguishing gas remain an important part of the Siemens portfolio. At this yearHannover Messe, Siemens will present another medium-voltage switchgear that doesn't require sulfur hexafluoride (Sulfr hexafluoride) as the insulating gas: the 8DAB 12. The system uses clean air consisting only of the natural constituents of ambient air as the insulating gas.Get price

Sulfur hexafluoride circuit breaker - Wikipedia

The first patents on the use of SF 6 as an interrupting medium were filed in Germany in 1938 by Vitaly Grosse and independently later in the United States in July 1951 by H. J. Lingal, T. E. Browne and A. P. Strom (Westinghouse). The first industrial application of SF 6 for current interruption dates to 1953. High-voltage 15 kV to 161 kV load switches were developed with a breaking capacity of 600 A.Get price
