S9 Series Oil-Immersion Power Transformer 35kv

The three-phase S9, S9-M series oil-immersed distributing transformer applies new type insulating structure and makessshort-circuit resistance strong. The iron core is made of high-quality cold-rolled silicon-steel plate. High-voltagewinding group is made up of high-quality oxygen-free copper lines and it adopts multilayered drum typet structure. All fasteners have been processed with special treatment to prevent them from loosening.
As the 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. Reliable Structure
With the fundament of traditional frames and proved techniques, our company made a great improvement, for instance:
A. We employ spiral loops with longitudinal oil path to produce a better interior cooling effect.
B. We improve the effectual support of the loop's teminal face to strengthen the anti-short circuit electricity capability.
C. We employ new suspending structure and instrument-positioning frames to guarantee that the long distance transport and movement will be more reliable.
D. In addition to those above, we have lots of novel and dependalbe frames that wait to serve you.
E. We are sure that, when you choose more advanced transformers, you will enjoy greater technique intensity.

2. 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.
A. We use high-quality silicon-steel plates which are of lower unit loss, and the no-load of the tranasformer is lower.
B. Wu use high-quality wooden laminating insulation pieces, which won't split or move even under the influence of of short circuit
C. Wu use thooughly filtrated tranasformer oil containing less water, gas and imupities, which makes our transformers work better
D. Wu 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 ISO900 inspection.

3. Good Technology and Economic Performance:
Compare with S7 Series product, S9 Series product reduces the no-load loss by 10%, load loss by 24% and no-load electric current by 46%, as a result, the operating cost will drop by 19%.
