where can I get SF6 Breakers tanks

I think we should clarify Live tank breaker vs. dead tank, as the volume of SF6 would be quite different in each application. Also - it is my understanding that an SF6 (dead tank) can still open normal load current 0 PSIG, as SF6 density is greater than air, so some will still remain in the tank at Low Low.

    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.
