Core-type and shell-type transformers have structural differences but uniform core material demands. Laminated silicon steel is their preferred choice for optimal performance and cost-efficiency, with future trends favoring energy-saving materials like amorphous alloys while it remains mainstream for traditional transformers.

Under the global trend of energy transition and energy saving, the efficiency of power equipment has become a core concern in the fields of power grids, new energy sources and data centres. Traditional silicon steel transformer core has high no-load loss, heat generation and other problems, amorphous metal transformer core with ultra-low loss, high efficiency and energy saving advantages, become a new generation of power distribution and special transformer core components.

In the power transmission system, transformer is the core equipment, and its performance is related to the stability and efficiency of power supply. As a key component of the transformer, the design of the core has a significant impact on its operational efficiency, temperature rise and life span. In the early days, transformers used solid iron cores, which had serious heat generation and energy consumption problems. With the development of technology, laminated iron core has become the mainstream choice to improve the performance of transformers because it can effectively suppress eddy current loss.
