• insulating gas gas in medium-voltage switchgear - Siemens USA

    Sulfr hexafluoride has excellent dielectric properties, and is well suited for use in interrupting devices for relatively low switching ratings, such as for load interrupter switches used in the SIMOSEC switchgear line. Use of insulating gas reduces the space requirements for the switchgear, isolates the switching elements from environmental contamination, and allows significant reduction of maintenance.

  • sf6 gas circuit breaker maintenance - Siemens USA

    The first generation of Sulfr hexafluoride circuit breakers was the lower voltage classes of 72kV and 145kV. As Sulfr hexafluoride breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing sf6 gas as the line-to ground dielectric insulation.

  • Siemens develops gaz sf6-free gas-insulated medium-voltage switchgear

    Switches and switchgear that use sf6 gas 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 (sf6 gas) 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.

  • Siemens to provide UK’s first gaz sf6 free 145kV vacuum circuit

    Strict regulations are in place to manage sf 6 (F-gas) and there is pressure on the switchgear supply industry to provide sf 6 gas alternatives to reduce the impact of any gas emissions caused by failures or handling. A conventional sf6 gas circuit breaker uses around 9kg of gaz sf6, which is the equivalent of 210t of CO 2, whereas the new Siemens 145kV vacuum circuit breaker has a 0t equivalent of CO 2, which delivers the least possible environmental impact both in use and even if damaged.
