  • 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.

  • An alternative to SF6 in electrical switchgear - EE Publishers

    The company has already developed and commissioned air-insulated high-voltage circuit breakers that use carbon dioxide (CO 2) as an insulating and arc-quenching medium, and medium-voltage ring main units (RMUs) that use air in a gas-insulated switchgear design. However, these solutions are only part of the picture – an SF 6 alternative is needed that can be used in a wider field of applications.

  • What are the alternatives to SF6 gas? - ECA Today

    Mar 31, 2020SF 6 is a colourless, odourless, non-toxic gas which is five times denser than air. It has been increasingly deployed in circuit breakers and switchgear in a global array of power stations, wind turbines and electrical sub-stations, to quench arcs and stop short circuits. Often, it replaced oil-filled circuit breakers which contained harmful PCBs.

  • ALTERNATIVE GAS INSULATION IN MEDIUM-VOLTAGE

    A few years ago ABB intensified the search for an alternative insulation. The identified alternative to SF6 is a mixture of a fluoroketone, developed by 3M Company, and a carrier gas. For medium-voltage switchgear, the most effective solution is a C5 fluoroketone, which has the best overall performance and a very low GWP of about 1.
