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. 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, thoroughly filtrated transformer oil and high quality rubber sealing material. All raw materials have passed the quality testing with national standard ISO9000 inspection.
Compared with previous products, S9 and above series reduces the no load loss by 10%, and load loss by 24%, and no load electric current by 46%. As a result, the operating cost will drop by 19%.
