The core of 110Kv power transformers is made of high-quality siliconsteel sheets, and laminated by steps. It is advantageous in low loss, low noise, and high short-circuit withstand capacity, etc. Now it is wildly used in power station, power plant, and gets high praise from them. SZ11- 63000/110 transformers have passed a complete set of National tests and the short-circuit withstand capacity test.

35Kv series transformers are with the following characteristics: low loss, low noise, protection against thunder and lightning, high short-circuit withstand capacity and beautiful appearance etc. It is made by advanced assembling lines and method, with qualified and refined accessories. It enjoys four remote functions: "remote communication, remote test, remote adjustment and remote control".

It adopts advanced electromagnetic design software, and meets IEC60076, GB1094, GB/T6451, GB/T252Q9-2010 standards. Without such device like conservator, air breather-., so it ensures that the transformer oil is not in contact with air, improving the anti-oxidation capacity of the transformer oil and delaying its aging. The core is made of high quality cold-rolled grain-oriented silicon steel sheet, with laminated structure miter joint, so as to reduce the no-load losses and no-load current.

Hermetical-sealed distribution transformer contain oil tank, which is completely isolated from air, oil tank compensates oil tank volume transformation, moisture or oxygen cannot enter in the tank, this can slow down insulation materials aging. There is no need check suspended core before running and free from maintenance after bring into operation, this may improves product operation reliability.

The wound core is made of cold rolled high carbon silicon steel sheet. It is wound into a closed frame-shaped structure by annealing treatment, Wound core is with high filling factor. There is no air gap in the magnetic circuit. Both HV and LV windings are continuously wound on the core limb with good concentricity and performance of tightness. With characteristics of low loss and low noise, it is the new generation of high-tech, high-performance, and energy-saving products, widely used in power supply and distribution system.

S13 energy-saving transformers are made of high quality magnetic silicon steel, with traditional core lamination process and optimized design. It decreases the no-load loss by 27% in average, currently second only to the latest generation of SBH15 amorphous alloy transformers. It has a high PPR (Performance to price ratio). Products are used in industrial and mining enterprises, residential quarters, as well as urban and rural power grids and other places.

Amorphous Alloy Transformers are a new type of trans¬formers with amorphous alloy as its core. The amorphous alloy is with relatively high magnet induction intensity, low coercive force, low loss, low magnetizing current and stability with temperature changes. Compared to S9 series transformers, its no-load loss decreases by 78-80%, and no-load current by 50%. It is highly energy-saving. Amor¬phous alloy transformer is green, environmentally friendly, energy saving, and highly efficient.

This transformer has good heat dissipation, and its coil does not absorb moisture. It does not pollute the environment, and can be installed in the loading center.Low noise and low loss. It is energy-saving, economic and free from maintenance. It has high mechanical strength, strong insulation and good short-circuit withstand capacity.It has good fire protection, anti - explosion and disaster- prevention performance. Low loss, small in size, light in weight, and easy to install.
