  • First SF6-free voltage transformers - Siemens Energy Global

    Worldwide, many TSOs intend to eliminate greenhouse gases for new installations of gas-insulated equipment and therefore continue to contribute to their voluntary self-commitment in SF 6 reduction. Until now, SF 6 -free voltage transformers were available for voltages up to 245 kV. Recently, Siemens has succeeded to expand the blue portfolio, which exists of a broad spectrum of CO 2 equivalent-free equipment for air-insulated and gas-insulated switchgear, with a 420 kV voltage transformer.

  • Alternatives for SF6 | 2020 | Siemens Energy Global

    Most prominent among available options are “clean air” solutions, i.e. purified air, and gas mixtures that both have a fraction of the climate impact of SF 6. Hermetically sealed systems with clean air as an insulating gas take up more space than SF 6 , but combined with digitalised current and voltage transformers these systems can be built as small as current SF 6 systems.
