At 10:58 am on February 4, 2026, two 80 MVA transformers were successfully installed in the 220KV substation of Yingkou Jianfa Shenghai Nonferrous Chemical Co., Ltd., marking a key breakthrough in the construction of the project's power core supporting facilities and laying a solid power guarantee for the overall operation of the project.
As the core power supply hub of Yingkou Jianfa Shenghai Nonferrous Chemical Co., Ltd., the 220KV substation undertakes the power transmission and stable supply tasks of key production systems such as smelting, electrolysis, acid production, slag selection, power, oxygen production, etc. It is the "heart" equipment of the project's energy security system. Since the start of the project, the construction unit has cooperated with multiple units such as construction, supervision, and equipment supply, strictly following the national power engineering construction specifications and industry standards, reversing the construction period, hanging maps, and promoting various processes with high standards.
During the construction process, the project team strictly implemented the main responsibility for safety production, strengthened the full process safety control and quality supervision, and successfully completed the core links such as the acceptance of the main transformer foundation and precise positioning. All participating personnel have overcome difficulties and worked together to achieve the goal of zero safety accidents, zero quality defects, and zero node delays, successfully achieving the installation node goal of the 220KV substation main transformer.
The successful installation of the main transformer in the 220KV substation has laid the foundation for electrical connection and station construction, provided guarantee for the power supply of the engineering project, and significantly improved the reliability and stability of power supply. It has also provided core support for the subsequent electrical system commissioning, protection setting verification, linkage testing, and the achievement of the production target in the second half of 2026.
Next, the project team will continue to strive for the construction period, accelerate the construction of remaining supporting projects, and make every effort to reach the production node. With high-quality projects, we will help promote the high-quality development of the local economy and contribute to the revitalization of the non-ferrous metal industry in Northeast China.
