Problem:
Inspection of this transformer revealed excessive leaking from the flange and fastener areas. The previous
method of repair was to de-energize, drain the tank and install new gaskets. De-energizing, draining the
tank and installing new gaskets would require a 6 week shutdown.
Solution:
Complete repair areas were sandblasted to a SSPC-SP5 white metal finish. All active leaks were stopped
using One Minute Epoxy and the Mark 5 Application System. Surface areas were then chemically cleaned
using Cleaner Blend 300. Fasmetal was applied directly over the One Minute Epoxy to a thickness of
.125” and extending beyond by .500”. A mold was manufactured from plywood and generously coated
with release agent. Release agent must be used for easy mold removal following full cure of Flexane 80
Liquid. The plywood mold was positioned around the repair area. Flexane 80 Liquid was mixed and
poured into the mold. Flexane 80 Liquid flowed evenly, encapsulated the complete repair area. Flexane 80
Liquid provided a flexible (350% elongation), vibration and climate resistant permanent seal.
