Brochure SF6 room Repair for transformers

Disconnect the SF6 from the vent valve so it can be used as normal to release the vacuum from the chamber at the end of the pour. Open the filling valve and slowly fill the mould. The idea behind this process is to mix SF6 gas into the atmosphere inside the vacuum chamber thus increasing the dielectric strength of any residual air that may remain trapped in the casting.
