  • SF6 gas in medium-voltage switchgear - Siemens USA

    The semiconductor industry uses SF6 gas in plasma etching and to clean chemical vapor deposition tools. SF6 has been used, usually together with argon, as a filler gas in thermally-insulated windows. Finally, in what seems a bizarre use, SF6 was used for the "gas cushion" in a number of sports footwear products, including some endorsed by widely-known sports figures.

  • Siemens develops SF6-free gas-insulated medium-voltage switchgear

    Switches and switchgear that use 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 (SF6) 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.

  • Essentials of SF6 monitoring | TD Guardian - Siemens USA

    Because SF6 has a global warming potential that is almost 24,000 times greater than CO2, it gets a lot of attention. And since the electric power industry is responsible for nearly 80% of the world’s usage, our industry has taken significant steps to reduce or eliminate the emissions from gas insulated switchgear.

  • Gas-Insulated Transmission Line (GIL) System Design

    Introduction to GilTechnical DataHigh em CompatibilityGIL systems are based on the successful SF6 tubular conductor technology, which has been around for several decades. GIL consist of a central aluminum conductor with a typical electrical cross section of up to 5,300 mm2. The conductor rests on cast resin insulators, which center it within the outer enclosure. This enclosure is formed by a sturdy aluminum tube, which provides a solid mechanical and electrotechnical containment for the system. To meet up-to-date environmental and technical aspects, GIL are filled with an insulating gas mixture of mainly nitrogen and a smaller percentage of SF6 gas. This concept also has logistic advantages.All elements such as tubes, angles and special modules are lightweight and small enough to be transported by comparatively light standard trucks.
