10kV S9 S9-M Series Distribution Transformer

Characteristic of Products
The three-phase oil-immersed distributing transformer applies new type insulating structure and makes short-circuit resistance strong. The iron core is made of high-quality cold-rolled silicon-steel plate. High-voltage winding group is made up of high-quality oxygen-free copper lines and is adopts multilayered drum type structure. All fasteners have been processed with special treatment to prevent them from loosening.

Excellent Materials
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.
We use high-quality silicon-steel plates which are of lower unit loss, and the no-load of the transformers is lower.
We use high-quality wooden laminating insulation pieces, which won't split or move even under the influence of short circuit.
We use thoroughly filtrated transformer oil containing less water, gas and impurities, which makes our transformers work better.
We use high-quality rubber sealing material, which can prevent the transformers from aging or leakage.
All raw materials has passed the quality testing, and all the raw material factories has pass through the national standard ISO9000 inspection.
