What is an oil-immersed transformer?

Oil-immersed transformer is a new type of high performance transformer with more reasonable structure and better performance. Because its three core columns are three-dimensional arrangements of equilateral triangles, there is no air gap in the magnetic circuit, the winding is closer, and the three magnetic circuits are the same length and the shortest, and the cross-sectional area of the core column is closer to the circle, so the performance is further improved, the loss is reduced, and the noise is reduced. Three balance, reduce the third harmonic component, the product is more suitable for urban and rural, industrial and mining enterprises grid transformation, more suitable for combined transformers and pre-installed transformer substation.
