Blue / Green / Red /Brown Color Enameled Copper Wire For Winding Coils
The production process of enameled copper wire is a complex and precise process that requires multiple links to ensure quality and performance.
First of all, we choose high-purity copper as raw material to ensure the conductivity and reliability of the product.
Then, by introducing advanced enameling technology, we evenly coat the insulating material on the copper wires to form a protective layer to prevent current leakage and short circuits.
Finally, a strict quality inspection process is carried out to ensure that each colored enameled copper wire meets industry standards and customer requirements.
