Product Description

 

1. Features of Products

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.

2. Reliable 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.

3. Excellent Materials

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.

5. Good Technology and Economic Performance
Compare 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%.
