Distribution transformer submerged by three-phase S13 series



The unparalleled distribution transformer by three-phase oil produced by our company adopts a new isolation structure to improve short-circuit resistance; The iron core is made of high quality cold rolled silicon steel sheets; The high-voltage windings are made of copper wire without high quality oxygen as material, and adopts a cylindrical structure of multiple layers; All robust parts adopt special treatment against loosening.

The product has the features of high efficiency and low loss, can save a lot of energy consumption and operating costs, and has significant social benefits. It is a new product of popularized technology.

2. Reliable structure

Based on the traditional structure and mature technology, our company has made many improvements, such as:

1) spiral coil with passage of longitudinal oil, better internal heat dissipation;

2) improved the efficient support of the end of the coil end, and the ability to resist the short circuit current is stronger;

3) the new elevation structure and the body positioning structure are adopted to ensure that they are more reliable in transport and long-distance operation;

4) We have many unique and reliable structures to serve you;

5) The selection of a transformer with a higher level of performance will have a higher level of technical content.

3. Excellent materials

1) an oxygen-free copper cable is selected with less resistivity, and after a series of additional surface treatments, it is softer and softer-free from burrs and sharp corners, which makes the load loss of the transformer lower and the Electrical performance is more reliable.

2) Select high quality silicon steel sheets. With the improvement of the performance level, use silicon steel sheets with lower unit loss to make the loss without load of the transformer becoming lower.

3) Select high quality laminated wood insulation parts, without cracking, even under the action of short circuit current, the cable will not move.

4) The transformer oil is selected after deep filtration. The lowest water, gas and impurity levels make the transformer work more reliable.

5) Select high quality rubber sealing materials to effectively avoid aging and avoid leakage.

6) All raw materials have passed the quality inspection, and all manufacturers of raw materials have suffered a strict review in accordance with the ISO9000 National Standard.

4. Technical and economic performance.

On the basis of the S11 series, the S13 series products have further reduced the loss without load, the current ratio without load, the increase in temperature and noise, and further optimized their performance.
