  • Alternatives for SF6 | 2020 | Siemens Energy Global

    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. In addition, they are durable and can be used without any problems at the lowest temperatures - down to -50 degrees Celsius.
