Product Description

The series of products, which are more advanced, are greatly improved and upgraded in their materials, structures and technique.

The high-low pressure clamps are strained by steel drawstrings, cross bars or side frames, forming a solid frame structure, which strengthens the clamping force of the iron core and its durability against impact from transportation.

Besides, they have good capability of bearing short circuit with beautiful apperance, liable operation, low consumption and noises, meeting the advanced standards of similar products abroad. The samples of transformer SZ11-8000/34 produced in the Company have passed the short-circuit test conducted by the Chinese transformer test center for one time.

The high-low pressure coils are longitudinally set for better heat dissipation, which can reduce the temperature difference of Chinese wood oil and temperature rise of the hottest spot inside coil.

Features & Advantages

1 Low partial discharge: the apparent discharge quantity is usually less than 100pC;
2 Low noise: Product of 63MVA or below 63MVA has a noise level less than 60dB;
3 Low loss: no-load loss is reduced by 20 percent compared with that specified in national standards;
4 High anti-short capability: the SFZ10-40000/110 transformer has passed the short-circuit test carried out by China National Transformer Quality Supervision Testing Center.
5 Most competitive shipping rate from our own shipping forwarder.

High-quality material

a. The three- phase oil-immersed Power Transformer applies new type insulating structure.
b. The iron core is made of high-quality cold-rolled silicon-steel plate 27ZH10.
c. All fasteners have been processed with special trearment to prevent them from loosening.

d.Oxygen-free copper lines of lower resistivity, which will become 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.
e.High-quality wooden laminating insulation pieces, which won’t split or move even under the influence of short circuit.
f. Thoroughly filtrated transformer oil containing less water, gas and impurities, which makes our transformers work better.
h.High-quality rubber sealing material, which can prevent the transformers form aging or leakage.
