Oil cooled transformer

Product Description

The Core is build up from interleaved low loss cold rolled, grain oriented Silicon Steel laminations. Individual stampings are coated on both sides with an insulating material, which is both oil and temperature resistant. The core limbs are securely bound with heavy duty webbed cotton taps and the yokes are firmly clamped between steel channels, all cores have mitered joints. Top and bottom clamps are secured to each other by means of tie rods which serve the dual purpose of securing the windings in place and of transfering the load from the bottom to the top clamps when the core and windings are lifted. This prevents tensile stresses being set up in the core legs which could adversely affect the iron losses.
