As is known, power and distribution trasformers are the crucial and expensive components of the transformer box. These components, with good maintenance, especially of the cooling system components, can run efficiently during the desired intervals. We select the best painting method and materials in accordance with the customer desires and the suggestions of our painting facility, and we produce100 % coated, corrosion ressitant surfaces.
Pouring painting is the most common method used in transformer tanks and allows components like corrugated walls, thermometer pockets, bushing attachment point, collars to be covered completely. Besides the inner walls of the tank can be painted, as a result the surface protection application is provided in the best way.
Okuyan Metal Mühendislik San. and Co. Ltd. presents you sanding, zinc coating and painting processes all together. Tanks have been painted after beeing gone through sanding process, have a longer life than those which have been painted with traditional methods.
