S11-M-30 KV series fully sealed distribution oil-immersed transformer 

Oil immersed transformer is a new type of high-performance transformer with a more reasonable structure and better performance. Its three-dimensional coiled iron core, due to the equilateral triangle arrangement of its three core columns, has no air gap in its magnetic circuit and is wound more tightly. The length of the three magnetic circuits is the same and the shortest, and the cross-sectional area of the core columns is closer to a circle. Therefore, the performance is further improved, the loss is reduced, the noise is reduced, the three aspects are balanced, and the third harmonic component is reduced. This product is more suitable for urban and rural, industrial and mining enterprise power grid transformation, and is more suitable for combination transformers and prefabricated substation transformers.
