Copper-clad aluminum flat strip  are coils for power transformer coils, windings for AC/DC motors, busbars (busbars) in high- and low-voltage power distribution cabinets, and connecting conductors for high-current power transmission and distribution industrial equipment in the electrical and electronic industry. . The market demand for copper-clad aluminum flat wire and busbar in the electrical and electronic industry is very impressive. At present, some copper-clad aluminum wire production enterprises have realized the economic value of this product and started research work. Our company started earlier. One of the enterprises that carried out basic research on copper-clad aluminum flat wire has achieved remarkable results. At present, the research and development work of copper-clad aluminum flat wire has been among the highest in the country.
