Substation B SF6 Leaking Flange Repair
SF6 substation 3x leaking GIB/GIB flanges
September 2021 -- Composite encapsulated leak repair – large flange, GIB/GIB straight, large resin fill. The 3X ReflangeKit® concept is based on a composite double shell system that encapsulates the leaking flange. The first shell covers and protects the flange collecting SF6 leaks. The second shell contains specific resin. An exhaust valve allows the SF6 gas to escape during resin injection. After overnight curing of resin, the valve is closed and sealed giving a 100% seal and leak free composite repair.
