EXPANSION TANK TRANSFORMER

Core and coil structure of transformers with expansion tanks are the same as hermetic transformers. The dimensions of the expansion tank are calculated and designed to store the expansion of oil that increases with temperature. It is open to the atmosphere and the moisture in the air is prevented from penetrating the oil in the transformer by means of silica gel (air dryer). Expansion tank dimensions on the transformer; It is designed in accordance with the expansion of the heated oil.
