Arresting Transformer Oil Leakage using 100% Solid Epoxy

image

Problem:

Oil was found to be leaking time and again on a transformer around the ceramic insulator and steel joint areas, despite repeated application of various Multipurpose Sealant’sthat failed to withstand extended durations. Asa result, the client was required to constantlymonitor the oil leakages which for obvious reasons was extremely tedious and time consuming.

Solution:

Upon assessing the situation and associated problems, Arudra identified that the solution to arrest the leaks would be to use a 100% solid epoxy ceramic putty on top of a strong epoxy sealant. The application was carried out as per Duromar’s methodology, wherein the surface preparation was carried out around the leakage areas and a masking tape was used to help enhance the coating application.
Upon completion, the Duromar DuroStik was used to arrest the leak and this was later covered with Duromar SAR - UW, a 100% solid ceramic Epoxy Putty.
Duromar DuroStik is an extremely fast curing putty material, packaged in a single tube for easy mixing and use. Ideal for storing in toolboxes to make quick repairsor to stop leaks in steel, aluminum, fiberglass or concrete.

Duromar SAR - UW is a versatile easy-to-use rebuilding putty with excellent abrasion and chemical resistance. This product is heavily filled with aluminumoxide and can be built up to an inch in thickness or more

Result:

Upon application, it was noticed that the oil leaks were thoroughly arrested and the coating held strong for extended durations due to the high adhesion levels ofthe 100% solid epoxy putty. A key advantage of using an epoxy to arrest such leaks is that there would be no need for the oil to be drained out before application considering the ceramic epoxy putty is 100% solid and hazard-free when handled. This not only helps saves ample time and effort but also proves to be superior in performance - Thereby eliminating unforeseen Operations & Maintenance costs.
