In the magnificent development process of the power industry, every technological leap is like a bright star, illuminating the way forward for mankind. Now, a new star named "the world's first 110kV amorphous alloy three-dimensional coiled core power transformer" shines with a unique light in this vast starry sky, outlining a desirable picture for the future of green power.
1. Technological breakthrough: an energy-saving model that integrates amorphous alloy and three-dimensional coil core
The advent of this transformer can be called a revolutionary breakthrough in the field of power technology. Its core innovation lies in the deep integration of low-loss amorphous alloy materials and three-dimensional coiled core structure, and realizes the reliable suspension of amorphous alloy three-dimensional coiled core weighing more than 10 tons through the new core suspension structure. This innovative design not only reduces noise, but also significantly improves the transformer's resistance to short circuits. The amorphous alloy material has excellent magnetic properties and low loss characteristics, while the three-dimensional coiled core structure can further reduce the magnetic flux density and core loss. The combination of the two makes the transformer perform well in terms of energy saving, and its no-load loss is reduced by more than 60% and the load loss is reduced by more than 5% compared with the level 1 energy efficiency limit value in GB 20052-2024.
Taking a single transformer with a capacity of 20,000 kVA as an example, it can save 120,000 kWh of electricity per year, which is equivalent to reducing carbon dioxide emissions by 72 tons. Behind this data is the technical team's countless tests and optimizations, which is a bold breakthrough in the traditional transformer design ideas. They have overcome a number of technical problems such as the large-scale rolling process of amorphous alloy strips, annealing technology, and the improvement of the anti-short-circuit ability of the core, and strictly control each step of the process such as core winding and body assembly to ensure that the product has low operating noise, strong anti-short circuit ability, and long-term safe and reliable operation.

The entire R&D team has applied for more than 10 patents, demonstrating China's strong innovation ability in the field of power equipment.
The achievement of this achievement is inseparable from the close cooperation and collaborative innovation of all parties, and is a model work of the combination of production, education and research. The joint R&D team of Guangdong Power Grid Corporation, Haihong Electric Co., Ltd., Huazhong University of Science and Technology, North China Electric Power University and Antai Technology is committed to contributing to the green transformation of the power industry with a high sense of responsibility and mission. Their efforts have not only led to the successful launch of products, but also won an international reputation for China's power equipment manufacturing industry.
3. Industry impact: Promote the green transformation of the power industry
As an important area of carbon emissions, the green transformation of the power industry is essential to achieve "dual carbon". The successful development of the transformer provides a practical solution for carbon emission reduction in the power industry, and its popularization and application will help reduce the operating loss of the power system and improve energy efficiency. With the continuous optimization of China's energy structure and the large-scale access of new energy power generation, the demand for high-efficiency and energy-saving substation equipment is growing. The transformer's energy-saving, safe and highly reliable characteristics will provide strong support for the transformation of a new power system based on new energy sources, and help the green and low-carbon transformation of China's energy structure.
From an economic point of view, taking a single transformer with a capacity of 20,000kVA as an example, it can save 120,000 kWh of electricity per year, which not only means a significant improvement in environmental benefits, but also brings tangible economic benefits to enterprises. In the context of the current efforts of the whole society to improve the quality of the environment, this technological innovation has undoubtedly injected new vitality into the sustainable development of the power industry.
4. The future outlook: to lead the global development of energy-saving transformer technology
