Product Description

S9 series oil-immersed power transformer 10KV class:

Features

The three-phase oil-immersed distribution transformer applies new type insulating structure. The iron core is made high-quality cold-rolled silicon-steel plate. High-voltage winding group is made up of high-quality oxygen-free copper lines 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.

Advantage of structure

1. we employ sprial coil with longitudinal oil path to make a better interior cooling effect;
2. we improve the effective support of the coil's terminal surface to strengthen the anti-short circuit current capability;
3. we employ new hoisting structure and body-positioning frames to guarantee that the long distance transport and movement will be more reliable;
4. cancelled the oil tank, the wave wings of tank instead of the tubing as a cooling device, corrugated tank is made of high quality cold press sheet on dedicated machine and enhance the reliability of running.

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

Improved from S9 series product, S11 series product reduce the no-load loss by 30%,no-load electric current by 70~85%, average temperature by 10K,nosie level by 2~4db, and double the products service life. even under 20% overloads, it can also work for long period of time .
