  • SF6 gas in medium-voltage switchgear - Siemens USA

    SF6 is used in the SIMOSEC switchgear design for the load interrupting switch and for the switch-disconnector in a variety of configurations. This design takes advantage of the main characteristics of SF6 and minimizes the environmental issues associated with the gas. The switch is enclosed in a welded stainless-steel vessel of enclosure.

  • Alternatives for SF6 | 2020 | Siemens Energy Global

    With this, the demand for SF 6 has grown, as it is the gas mostly used in switchgear. After all it’s largely safe to handle and allows for space-saving switchgear-designs. But more and more often, SF 6 is no longer the gas of choice. For a simple reason: if the gas escapes, it contributes to climate change.
