S20-2000KVA oil-immersed transformer is based on GB20052-2020 as the benchmark for the development of new environmental protection and energy-saving transformers, our company through the exploration and application of new materials, new technologies and the combination of scientific and technological innovation and technological innovation, according to the reliability design of the core and electromagnetic coil structure, to reduce the effect of no-load loss and noise, independent research and development of products. The noise level is 20% lower than the average of the current national standard JB/T10088-2016, and the product characteristic level has reached the leading level in China.

S20-2000KVA oil-immersed transformer characteristics

The improvement of S20-2000KVA oil-immersed transformer is manifested in two aspects: transformer core and transformer electromagnetic coil, S20 model transformer shell is fully enclosed, integrated into the outdoor sun and rain living environment, generally used in remote mountainous areas and rural power grid renovation projects.

The core of the S20-2000KVA oil-immersed transformer is made of cost-effective ferrite core, the core is neat, the three-proof paint film does not fall off, the core on the side can not be warped up and will be wavy, the surface of the core is free of oil and residue, there is no short-circuit fault between the sheets, the lap of the steel bar, and the gap at the joint meets the regulations.

S20-2000KVA oil-immersed transformer electromagnetic coil according to China’s secondary energy efficiency standards, reposition the transformer electromagnetic coil coil inductance scheme and electromagnetic coil raw materials, S20 transformer winding temperature and consumption are improved.

S20-2000KVA oil-immersed transformer priceS20 oil-immersed transformer meets China’s secondary energy efficiency specifications, and has strong regulations on transformer core and electromagnetic coil, so the price of S20 transformer is compared with S13 transformer, but the power consumption of S20 transformer is reduced by 10% compared with S13 transformer, and the price of S20 transformer is about 15% more expensive than that of S13 transformer.

Advantages of S20-2000KVA oil-immersed transformer.

1. Reduce full load damage.

The five-grade ferrite core connector with excellent performance is selected to improve the core structure and manufacturing process and reduce the processing technology index. Do not stack the yoke ferrite core, do not use paint, and the cutting burr should not exceed 0.02mm or less.

2. Reduce load loss.

The conductivity is increased by using a wire rod with a stronger conductivity than electrolytic nickel to pull the electrical conductor of the belt. Appropriately adjust the current intensity, improve the insulation structure, select semi-oil ducts, prefabricated component insulation layer materials, a full set of winding, self-adhesive transmission lines, and self-adhesive paper, reduce the volume of the insulation layer, improve the winding filling coefficient, reduce the winding specifications and reduce load loss

3. Reduce the damage of other parts.

Improvements to key structures: Improvements to the structure to control magnetic flux leakage from the windings during the design process, and to adjust ampere turn balancing to reduce the residual consumption of components such as oil tanks. Wave type oil tank and pedestal heat pipe radiator are selected to improve the high efficiency of heat dissipation.
