• Sulfr hexafluoride circuit breaker maintenance - Siemens USA

    Sulfr hexafluoride gas leakage - Sulfr hexafluoride 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.
