plants,transformer substation ,large industrial mining and petrochemical enterprise and so on.
Advantage of materials
1.because 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 the electric performance is better.
2.We use high-quality silicon-steel plates which are of lower unit loss, and no-load of the transformers is lower;
3.We use high-quality wooden laminating insulation pieces, which won't split or move even under the influence of short circuit;
4.We use thoroughly filtrated transformer oil containing less water ,gas and impurities, which makes our transformer work better;
5.We use high-quality rubber sealing material, which can prevent the transformers form aging or leakage;
6.All materials has passed the quality testing, and all the raw material factories has pass through the national standard ISO9000 inspection.
Advantage of technology
Temperature control device:
The transformer adopts the BWDK series signal thermometer. The temperature measuring element is embedded in the upper half of the low-voltage coil, which can automatically detect and display the respective working temperature of the phase coil, and has the function of over temperature alarm and trip.
