Recently, the 220 kV/250 kV megavolt ampere transformers at the Sardur substation in Namangan, Uzbekistan were successfully powered. Shandong Electric Power, a subsidiary of China Electrical Equipment, supplied 30 transformers to the substation, including 4 220 kV, 2 110 kV, and 24 distribution transformers.

The Saldor substation is one of the important power nodes in Namangan, providing stable power supply for surrounding industries, agriculture, commerce, and residential life. The current substation equipment is mostly old equipment, with a transformer capacity of two 125 megavolt ampere transformers. With the socio-economic development of Namangan, the load of the Saldor substation continues to increase, and it is necessary to further improve the transformer load rate. The State Grid Corporation of Uzbekistan has requested a capacity increase and replacement of the main transformer, increasing its capacity from 125 megavolt amperes to 250 megavolt amperes. The operation of this transformer provides strong support for the production and daily electricity consumption of residents in Namangan Island, further enhancing the safe and stable operation and load supply capacity of the Namangan Island power grid to meet future load demands.

During the project promotion process, due to the fact that Uzbekistan's power equipment uses GOST standards, which differ significantly from common IEC and GB standards, Shandong Electric International Marketing Center actively communicated with foreign clients, strengthened cooperation, and formed a design team to study technical solutions and GOST standards. After two months, the GOST technical standard conversion was successfully completed. At the same time, electromagnetic scheme design is strictly carried out in accordance with GOST standards. Through multi physics field simulation analysis, the distribution of magnetic field, electric field, and temperature field of the product is simulated under various working conditions, and the product structure is optimized to have the characteristics of low loss, high overload capacity, and high reliability. Continuously improving the design scheme to ensure meeting customer requirements has achieved project and technological breakthroughs for the enterprise in Central Asia.

Shandong Denko Electric relies on its layout and brand advantages in overseas markets to accelerate the expansion of overseas business and promote the implementation of globalization strategies. At present, the supply of all transformer equipment for the first phase of the renovation of Uzbekistan's main power grid has been successfully completed, and has won the trust of customers with high-quality products and services. It has been listed as a comprehensive strategic partner and high-quality supplier of Uzbekistan's Ministry of Energy in 2030.
