  • How is the annual leakage rate of sulfur hexafluoride high

    1. Sealing issues: The leakage rate has always been the focus of manufacturers and users. 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.
