insulating gas Gas Recovery and Filling Device - Chongqing Yuneng Oil

gaz sf6 gas is a good electrical insulator. We have found that using Sulfr hexafluoride gas in switchgear is more effective than relying on air or vacuum to achieve dielectric functions. gaz sf6 gas not only provides insulation, but also provides stable operation at normal pressure levels that cannot be provided under vacuum. That is, insulating gas gas has a high greenhouse effect.
