Enameled Copper Clad Aluminum Wire(XINYU), as the name implies, is a wire that surrounds the aluminum core wire with a copper layer. The types of enameled copper clad aluminum wire can be divided into enameled copper clad aluminum wire for signal or communication purposes and enameled copper clad aluminum wire for power supply according to its use.

Enameled copper clad aluminum wire has many advantages, can effectively reduce AC resistance, and is very economical. The AC resistance is the main basis of the current-carrying capacity. According to the principle of the skin effect, the surface of a single wire passes through a current larger than the current per unit area of the wire, that is, the center of the large-section conductor. In the circular area where the same conductor is formed, the center of the circle is smaller than the current passing through the circumference, so it is most reasonable and economical to combine the center conductor and the circumference conductor with different metals.

Although the enameled copper-clad aluminum wire has already been produced and gradually applied, the enameled wire industry is still in the stage of product development and certification, and the establishment of corporate standards. However, with the gradual improvement and recognition of the national standards and regulations, the enameled copper-clad aluminum wire will surely become standardized, thus driving the development of the entire industry.
