The power transformer industry welcomes new opportunities, and advanced manufacturing equipment becomes the core of enterprise competitiveness

With the acceleration of global energy transformation, the large-scale grid connection of renewable energy sources such as wind power and photovoltaics, and the continuous deepening of smart grid construction, the market demand for power transformers, as the core equipment for energy transmission and distribution in the power system, continues to rise. At the same time, downstream industries have put forward higher requirements for the performance, efficiency and stability of power transformers, which also drives the upstream power transformer manufacturing equipment to upgrade to intelligent, high-precision and high-efficiency directions, injecting new momentum into the development of the industry.

Power transformers: the “critical link” in energy transformation

Driven by the global "dual carbon" goals, the power system is undergoing profound transformation. Whether it's ultra-high voltage (UHV) projects for long-distance power transmission, the intelligent transformation of urban distribution networks, or ensuring power supply for data centers, renewable energy power plants, and other scenarios, power transformers are essential. According to industry research, the global power transformer market will exceed $30 billion in 2024, with a projected compound annual growth rate of over 6.5% from 2025 to 2030. High-efficiency, energy-saving, and intelligent transformers are the mainstream products in the market.

To meet market demand, domestic and international companies are increasing their investment in technological research and development. For example, high-efficiency, energy-saving transformers, by adopting new core materials (such as amorphous alloys) and optimizing winding structure design, reduce no-load losses by 30%-50% compared to traditional products, meeting stringent energy efficiency standards globally. Furthermore, intelligent transformers with condition monitoring and fault warning capabilities provide real-time operational data feedback, significantly improving power system reliability and O&M efficiency. These transformers are already widely used in smart grid projects in Europe, the United States, Southeast Asia, and other regions.

Manufacturing equipment upgrade: Laying a solid foundation for transformer quality

In core manufacturing, the fully automatic core shearing line, leveraging a high-precision servo system, achieves shearing error control of silicon steel sheets within ±0.1mm. Intelligent layout algorithms also reduce material waste, increasing material utilization by 5%-8%. In the winding process, CNC winding machines support automatic winding of various coil sizes and are equipped with an automatic tension control system to ensure uniform coil tightness, significantly reducing product loss. Furthermore, integrated transformer vacuum drying equipment and intelligent testing equipment are becoming increasingly common, enabling intelligent control of the entire process from production to testing, effectively improving product qualification rates and production efficiency.
