[ Product description] China supplier oil type step up and step down power distribution transformer
| Model Name: | Oil immersed transformer
|
| Advantages: | a. The cancellation of oil conservator makes the transformer more c onvinient to use;
b. The replacement of oil tube into corrugated tank makes the transformer easier to cool;
c. The physical property of corrugated tank increases the reliability of the transformer
d. The adoption of sanforizing makes sure the robustness of long distant transportation. |
| .Applications: | A.Mentallurgy and petrifaction;
B.Electric power system. |
| Detailed images | 1.Reliable Structure:
Spiral loops with longitudinal oil path to produce a better interior cooling effect; Improve the effectual support of the loop's terminal face to strengthen the anti-short circuit electricity capability; New suspending structure and instrument-positioning frames to guarantee that the long distance transport and movement will be more reliable.
2.Excellent Materials:
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 the electric performance is better.
High-quality silicon-steel plates which are of lower unit loss, and the no-load of the transformers is lower.
High-quality wooden laminating insulation pieces, which won't split or move even under the influence of short circuit.Thoroughly filtrated transformer oil containing less water, gas and impurities, which makes our transformers work better.
High quality rubber sealing material, which can prevent the transformers form aging or leakage. |
