With the development of the power industry, the capacity of a single transformer is increasing day by day. Therefore, the power industry proposes improvement requirements for the structure of transformers in accordance with the principles of increasing capacity, saving materials, improving labor productivity, reducing costs, and reducing usage volume, in order to improve the operational efficiency and reliability of transformers.copper strips for transformer is megatrends Traditional transformers use wire winding structures (oil immersed transformers), while transformers with strips winding structures made of pure copper strips (dry transformers) have extremely high dynamic and thermal stability, especially in short circuit conditions;High space utilization rate; The manufacturing process is simple and can be automatically wound, making it easy to achieve mechanized production with high winding efficiency; Uniform heat distribution, small volume, light weight, large capacity, material saving, good energy-saving effect, low no-load loss, good heat dissipation performance, easy welding, no axial force, long service life, no pollution, lifelong maintenance free, and many other advantages have been widely used in transmission and distribution engineering, and will gradually replace transformers with wire winding structures.

Correspondingly, copper strips for transformer used for high-voltage windings are called high-voltage strips, and copper strips used for low-voltage windings are called low-voltage strips. At present, there are dry-type transformers that use copper strips for transformer winding on both high and low voltage sides, as well as dry-type transformers that use copper wire on the high voltage side and copper strips on the low voltage side. Copper strips is also used for winding the low-voltage side of oil immersed transformers.
