The Oil Immersed Transformer is a high-performance transformer with a more reasonable structure and better performance. The iron core is made of an electrical steel strip, and the laminations at all levels are prepared in order according to the section shape of the iron core column and iron yoke. Each lamination must be stacked directionally in strict accordance with the stacking order to reduce hysteresis loss and eddy current loss. Therefore, the performance is further improved, the loss and noise are effectively reduced, the balance of the three is achieved, and the third harmonic component is reduced. Step down transformer is commonly used. This product is more suitable for the upgrading of urban and rural power grids, can meet the power needs of industrial and mining enterprises, and is also an ideal choice for combined transformers and prefabricated substations.

Oil Oil-immersed transformers use oil as the main insulation means transformers. As a cooling medium, oil plays an important role in many kinds of cooling methods, such as oil-immersed self-cooling, oil-immersed air cooling, oil-immersed water cooling, and forced oil circulation. The main components of the transformer are an iron core, winding, oil tank, conservator, respirator, Pressure Relief Valve, radiator, insulating sleeve, Tap Changer, Gas Relay, thermometer, etc.

The noise of an oil-immersed transformer is low because the oil can penetrate the silicon steel sheets of an oil-immersed transformer for a long time, and the transformer oil has an elastic buffer effect.

The Oil Immersed Transformer has the characteristics of good heat dissipation, low loss, large capacity, low price, etc. Its main role in the power grid is the conversion of electric energy, that is, the conversion of voltage level. It is understood that most of the power transformers operating in the power grid are oil-immersed transformers.
