sf6 gas switchgear solutions Siemens

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.

  • SF6 circuit breaker maintenance - Siemens USA

    SF6 gas leakage - SF6 breakers (live and dead tank) typically have a combination of static seals (O-rings and gaskets) as well as dynamic seal assemblies where the mechanism energy is transferred through to the interrupter assembly. Over time, seals degrade due to environmental conditions and exposure and will need to be replaced.
