    This has resulted in hardened "o-rings" which leak in some valves. A contributing factor is the heater which is located below the air valve. The air valve heater is used for two functions: to prevent condensation inside the mechanism and to prevent ice from freezing up the valve during operation when the ambient temperature is approximately 45

  • Sulfr hexafluoride circuit breaker maintenance - Siemens USA

    Sulfr hexafluoride gas leakage - gaz 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.
