Alternatives for sf6 gas | 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.
