110kV energy-saving amorphous alloy 3D wound core oil-immersed power transformer reaches the international leading level in terms of comprehensive performance.

Under the background of the global strict control of carbon emissions, China has clearly put forward the carbon peak, carbon neutral into the national development strategy. As a key area to achieve the “double carbon” goal, the whole society is accelerating to clean and low-carbon transformation. In this wave of the times, led by the Guangdong Power Grid, Haihong Electric as the main development unit, combined with elites from Huazhong University of Science and Technology, North China Electric Power University, and Advanced Technology & Materials Co., Ltd. , successfully developed the world's first 110kV energy-saving amorphous alloy 3D wound core oil-immersed power transformer, and on March 8, 2025 passed the China Machinery Industry Federation of the organization of the new product technology appraisal. The appraisal committee agreed that the comprehensive performance of the product has reached the international leading level, and agreed to product identification.

Innovative technology to open up the green future of high-voltage substation equipment

The operation loss of high-voltage transformer equipment is usually large, especially in remote areas, vehicle-network interaction and new energy and other fields, where no-load loss accounts for a high percentage. Through technological innovation (such as low-loss materials, optimized structural design), the loss can be significantly reduced, providing important support for energy saving and emission reduction in the power industry. 110kV energy-saving amorphous alloy 3D wound core oil-immersed power transformer through the combination of very low-loss amorphous alloy strip and energy-saving 3D wound core technology, and the use of new core suspension structure, successfully solved the large amorphous alloy core transformer stability problems, reduce operation noise, and adopt new type of core suspension structure, successfully solve the large-scale amorphous alloy transformer. Stability problems, reduce operating noise, and significantly improve the short-circuit resistance. This breakthrough marks the long-term obstacles to amorphous alloy transformer to the development of high-voltage large-capacity problem, has been perfectly solved.

110kV energy-saving amorphous alloy 3D wound core oil-immersed power transformer no-load loss than GB 20052-2024 in the level 1 energy efficiency limit value decreased by more than 60%, than the current large-capacity transformers still running on the grid more energy-saving and power saving. In the whole society to encourage the elimination of high energy consumption equipment background, 110kV energy-saving amorphous alloy three-dimensional coil core oil-immersed power transformers successfully launched, for the green transformation of high-voltage substation equipment to provide a strong energy-saving program for the high-voltage field of energy saving and carbon reduction and build a green low-carbon society provides an important green technical support.

Green technology to help new power system transformation

As the proportion of new energy in the power system continues to increase, the construction of new energy-based new power system has become an important direction of China's energy reform. 110kV energy-saving amorphous alloy 3D wound core oil-immersed power transformer can reduce the overall loss of the new power system, enhance the utilization efficiency of renewable energy. In addition, the product has strong short-circuit resistance and low operating noise, which can effectively cope with the impact of new energy power systems such as solar energy, wind energy and energy storage, and improve the stability of system operation. The product's low loss, low temperature rise and other highly reliable operating characteristics, extend the service life of the transformer, reduce the operation and maintenance costs of the power system, for the transformation of the new power system to provide stable, highly reliable equipment support.

Innovative achievements promote the green and low-carbon development of the energy industry

The technical achievement of 110kV energy-saving amorphous alloy 3D wound core oil-immersed power transformer fills the international blank, which not only brings revolutionary changes for high voltage equipment, but also has a far-reaching impact on the whole energy industry. With the widespread popularization of this product across the country, it is expected to save a lot of electricity and help reduce carbon dioxide emissions every year. This will inject a strong impetus for China to realize the goal of “double carbon” and promote the transformation of the energy industry into a green and low-carbon one.

Continuous innovation, leading the development of the industry

Guangdong Power Grid, Haihong Electric has always adhered to the concept of “science and technology is the first productive force”, with 110kV energy-saving amorphous alloy 3D wound core oil-immersed power transformer erected a new milestone of high-voltage equipment, showing the strength of China's manufacturing power and the imagination of China's creativity. This is also an important step towards a green future for the global power industry. Haihong Electric to real, sincere, sincere business philosophy, and continue to keep the right innovation, play as a breakthrough in the field of energy-saving transformers, for the country, society to make more contributions.
