Product Description

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 according to the section shape of the iron core column and iron yoke. Each lamination must be stacked directionally per the stacking order to reduce hysteresis and eddy current loss. Therefore, the product’s performance has been further improved, losses and noise have been effectively reduced, achieving a balance between the three, and reducing the third harmonic component, optimizing the overall operation. A step-down power transformer is commonly used. This product is more suitable for urban and rural power grid transformation, industrial and mining enterprises, as well as for combined transformers and prefabricated transformer substations.

Oil Immersed Transformers use oil as the primary insulation means and rely on oil as the cooling medium, 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 primary role in the power grid is converting electric energy, that is, converting voltage level. It is understood that most power transformers operating in the power grid are oil-immersed transformers.
