Product Description

As one of professional manufacturer in China, Dahu Electric would like to provide you Oil-Immersed Distribution Transformer. And we will offer you the best after-sale service and timely delivery.



The three-phase oil immersed distribution transformer produced by DAHU ELECTRIC adopts a new insulation structure, which improves the ability to withstand short circuit. The core is made of high quality cold-rolled silicon-steel sheet. High quality oxygen free copper wire is used in the high voltage winding as the material and it adopts multilayered drum type structure. All fasteners have been processed with special treatment to prevent them from loosening.


As high-tech product that promoted by the country, the product has many advantages such as high efficiency, low loss. Its social benefits are remarkable that it will save much of electricity consumption and operating cost.



1、We Choose oxygen free copper wires with 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 sheet,with the improvement of performance level, use lower unit loss of silicon steel sheet , so that the transformer no-load loss is lower.

3、We use high-quality laminate insulation, no cracking, even under the effect of short circuit current.

4、We use deep filtered transformer oil, lower water content, gas content, impurity levels, transformer work more reliable.

5、We use high quality rubber sealing materia, which can prevent the transformers from aging or leakage.

6、All raw materials through the quality inspection, and all the raw materials factories has pass through the national standard ISO9000 inspection.
