Coil Al 3 phase 25kv/400v 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 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 main insulation means of transformers and rely on oil as the cooling medium, such as oil immersed self coolin…
