Product Description

1.   Brief:

Our oil –immersed distribution 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 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.                                                                 

2.   Reliable Structure:                                                                              

With the fundament of traditional frames and proved techniques, our company made a great improvement. For instance:                                                                          

We applied spiral loops with longitudinal oil path to produce a better interior cooling effect;

We improved the effectual support of the loop’s terminal face to strengthen the anti-short circuit electricity capability;                                                                                    

We applied new suspending structure and instrument-positioning frames to guarantee that the long distance transport and movement will be more reliable.                                         

In addition to those above, we have lots of novel and dependable frames that wait to serve you .                                                                                                 

We are sure, when you choose more advanced transformers, you will enjoy greater technique intensity.                                         

3.   Excellent Materials:                                                                              

Because we use oxygen-free copper lines of lower resistivity, which will becomes 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 used high-quality silicon-steel plates which are lower unit loss, and the no-load of the transformers is lower.                                                                                   

We used high-quality wooden laminating insulation pieces, which won’t split or move even under the influence of shore circuit.                                                                     

We used thoroughly filtrated transformer oil containing less water, gas and impurities, which makes our transformers work better.

We used high quality rubber sealing material, which can prevent the transformers from aging or leakage.

All raw material has passed the quality testing, and all the raw material factories has been through the national standard ISO***0 inspection.

4.   Good Technology And Economic Performance

Compare with S7 series product, S9 series product reduces the no-load loss by *0%, load loss by *4% and no-load electric current by *6%; thus, the operating cost will drop by *9%.

Improved from S9 series product, S*1 series product reduces the no-load loss by *0%; no-load electric current by *0~*5%; average temperature by *0K; noise level by 2`4 db; and double the products’ service life. Even under *0% overloads, it can also work for a long period of time.

5.   Sealed Tank(M)

The “M” in S*1(M)R stands for the oil tank applied omniseal structure. Compared with common oil-immersed transformer, omniseal oil-immersed transformer taking off oil storage cabinet adopts wing-like corrugation for replacing oil tube as component of heat dispersion. The corrugated oil tank which is made up of high-quality cool-rolled plates is produced on the special produce lines. The wing-like corrugation will expand and compress that the volume of transformer dose, so that the transformer is separated from the atmosphere and can prevent or slower deterioration of oil and breathing of insulation. All these ensure the reliability of operation and without maintenance.

After the treatment of deoiling, derusting and parkerizing, the surface of corrugated oil tank is coated with paint which can provide rain-proofing, damp-proofing and salt haze-proofing. It is suitable for the use in the environment, such as metallurgy, petrochemical industry and mining, etc.,

6.   Core-folled(R)

The “R” in S*1(M) R stands for ribbon-wound core. It applied low-loss cold-steel plate of high quality. It has high degree of mechanization and it is not necessary to shear and punch which eliminate horizontal and longitudinal power connection of traditional iron core. So it secures lower no-load current to make the level of transformer’s reactive-power loss and noise lower which can conform to environmental requirements. With monolithic type iron core and compact coil, it has further short-circuit resistance.
