sulfur hexafluoride leak rate for Power Supply

Maintenance of hydrogen-cooled generators is critical for the safe and efficient operation of a power plant. This includes finding and repairing hydrogen leaks from the cooling system, which requires exhaustive searches on components, valves, fittings, or other locations. Unfortunately, traditional methods for hydrogen leak

News Detail
  • How is the annual leakage rate of sulfur hexafluoride high

    The annual leakage rate of SF6 load switch and inflator is below 1%/year. Switch life is generally about 30 years. Sealing should take into account the factors of compression, life, aging, and reliability of the sealing element.
