Coil copper 3 phase 25kv/0.4kv stepdown power transformer

The Oil Immersed Transformer is a high-performance transformer with more reasonable structure and better performance. The iron core is made of 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 in a directional manner in strict accordance with the stacking order to reduce hysteresis loss and eddy current loss., Therefore, the performance is further improved, the loss is reduced, the noise is reduced, the three items are balanced, and the third harmonic component is reduced. Step down 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 main insulation means of transformers 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 iron core, winding, oil tank, conservator, respirator, Pressure Relief Valve, radiator, insulating sleeve, Tap Changer, Gas Relay, thermometer, etc.

The noise of oil immersed transformer is low because the oil can penetrate into the silicon steel sheets of oil immersed transformer for a long time, and the transformer oil has elastic buffer effect.The winding is made of copper, which is more thermal stable, impact resistant and durable

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.
