Product Description

Hermetically sealed distribution transformer
1. We employ spiral loops with longitudinal oil path to produce abetter interior cooling effect;
2. We improve the effectrual support of the loop's terminal face to strengthen the antishort circuit electricity capability;
3. We employ new suspending structure and instrument-positioning frames to guarantee that the long distance transport and movement will be more reliable;
4. We use oxygen-free copper lines of lower resistivity, which will become smoother and burr-free after series of additional surface treatment, so the load loss of our transformer is lower and th electric performance is better;
5. We use high-quality silicon-steel plates which are of lower unit loss, and the no-load of the transformers is lower;
6. We use high-quality wooden laminating insulation pieces, which won't split or move even under the influence of short circuit;
7. We use thoroughly filtrated transformer oil containing less water, gas and impurities, which makes our transformer work better;
8. We use high high quality rubber sealing material, which can prevent the transformers from aging or leakage;
9. All raw materials has passed the quality testing , and all the raw material factories has pass through the national standard ISO***0 inspection.
