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.
The three-phase oil Immersed distribution transformer applies new type insulating structure and make the short-circuit resistance strong. The Iron core is made of high quality cold rolled silicon steel plate. High -voltage winding groups is made up of high quality oxygen free copper lines and it adopts multi drum type structure.
With the fundament of traditional frames and proved techniques our company made a great improvement for instance. We employ spiral loops with longitudinal oil path to produce a better cooling effect. We improve the effectual support of the loop's terminal face to strengthen the anti-short circuit electricity capability.
We use Oxygen free cooper lines of lower resistivity, which will become smoother and burr free after series of additional treatment so the load loss of our transformer is lower and the electric performance is better. We also use high quality silicon steel plate and high quality wooden laminating insulation pieces, and also we use thoroughly filtrated transformer oil and high quality rubber sealing material. All raw materials have passed the quality testing with national standard ISO90000 inspection.
