BDT-S9,S11 Transformer


Features of Products

1.Reliable structure.

Such as these improvement:

(1),Employ spiral loops with longitudinal oil path to produce a better interior cooling effect;

(2),Improve the effectual support of the loop`s terminal face to strengthen the anti-short circuit electricity capability;

(3),Employ new suspending structure and instrument-positioning frames to guarantee that the long distance transport and movement will be more reliable;

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 tratment,so the load loss of our transformer is lower and the electric performance is better.

Use high-quality silicon-steel plates which are of lower unit loss,and the no-load of the transfomers is lower;

Use thoroughly filtrated transformer oil containing less water,gas and impurities,which makes our transformers work better;

Use high quality wooden laminating insulation pieces,which won`t split or move even under the influence of short circuit;

Use high quality rubber sealing material,which can prevent the transformer from aging or leakage.

All raw materials have passed the quality testing,and all the raw material factories has passed trhough the national standard iso9000 inspection.

3.Good Technology and Economic Performance

Compare with S7 series,S9 series 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%.

Improved from S9 series,S11 series reduces the no-load loss by 30%;No-load electric current by 70-85%;Average temperature by 10K;Noise level by 2-4DB;And double the products`s service life.Even under 20% overloads,it can also work for a long period of time.

4.Sealed Tank.

Compared with coomon 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 as 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 oiltank 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.


It applies 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 pwer 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 environment requiremtnes.With monolithic type iron core and compact coil,it has further short-circuit resistance.
