Good quality comes to start with; service is foremost; organization is cooperation' is our enterprise philosophy which is regularly observed and pursued by our firm for high voltage distribution switchgear, prefabricated distribution compact substation, squared high voltage switchgear. We warmly welcome friends from all walks of life to visit our company to establish trade cooperation relationship and develop together. Our purpose would be to offer good quality products at competitive price ranges, and top-notch support to clients around the whole world. We've our personal manufacturing unit and sourcing business. We believe that every enterprise benefits from society's support and it is our duty to reciprocate by contribution to society.

The three-phase oil-immersed distribution transformer adopts a new type of insulation structure. The iron core is made of high-quality cold-rolled silicon steel sheet. The high-voltage winding group is composed of high-quality oxygen-free copper wire and adopts a multilayer drum structure. All fasteners are specially treated to prevent them from loosening.

As a high-tech product promoted by the country. This product has the advantages of high efficiency and low loss. Its social benefits are very significant, it will save a lot of power consumption and operating costs.

Structural advantage

1. We use spiral coils with longitudinal oil circuits to achieve better internal cooling effects;

2. We improved the effective support of the coil terminal surface to enhance the ability to withstand short-circuit current;

3. We adopted a new lifting structure and body positioning frame to ensure that long-distance transportation and movement will be more reliable;

4. The fuel tank is eliminated, and the corrugated wing of the fuel tank replaces the fuel pipe as a cooling device. The corrugated box is made of high-quality cold-pressed plates on a special machine, which improves the reliability of operation.

Material advantages

1. Since we use oxygen-free copper wire with lower resistivity, after a series of surface treatments, the copper wire will become smoother and free of burrs, so the load loss of the transformer is lower and the electrical performance is better.

2. We use high-quality silicon steel sheets, with lower unit loss and lower no-load transformers;

3. We use high-quality wooden laminated insulation, which will not split or move even under the influence of a short circuit;

4. We use transformer oil that has been fully filtered and has less moisture, gas and impurities to make our transformers work better;

5. We use high-quality rubber sealing materials to prevent aging or leakage of the transformer form;

6. All materials have passed the quality inspection, and all raw material factories have passed the national standard ISO9000 inspection.

Technical advantages

Compared with S9 series products, S11 series products have reduced no-load loss by 30%, no-load current by 70~85%, average temperature by 10K, noise level by 2~4db, and extended product life. Doubled. Even under 20% overload, it can work for a long time.
