Three-Dimensional Coil Core Three-Phase Oil-Immersed Power Transformer energy saving effect is remarkable.

OVERVIEW:


1. Low loss:

Due to the three dimensional wound core oil immersed transformer has the characteristics of small seamless magnetic resistance, the magnetic circuit at the corner is consistent with the magnetic direction of the silicon steel sheet, the winding compact packing coefficient is high, and the core weight is light.

Compared with traditional oil-immersed iron core transformer, no-load loss Po can be reduced by 18%-28%.

No load current Io decrease by 50%-60%.

Energy saving effect is remarkable.

 

2. Low noise: 

The noise level of three dimensional wound core oil immersed transformer is 5-10 db lower than that of laminated core oil-immersed transformer.

It is an ideal silent product.

 

3. High mechanical strength:

High mechanical strength: the three-dimensional rolling core adopts the regular circular core section, the anti-short circuit ability is better than the long circular section.

And pad block coverage is high, fastening effect is good, greatly improve the product's ability to withstand short circuit.

 

Normal service condition:

1. The altitude shall not exceed 1000m;

2. Environment temperature: the highest temperature + 40 ℃; 

3. The highest average daily temperature +30 ℃; 

4. The highest annual average temperature +20 ℃; 

5. Outdoor lowest temperature -25 ℃;

6. Installation environment: the ground acceleration caused by the earthquake is ag<2m/s.

Note: please consult with our company to solve the problem beyond the normal environmental conditions.
