Polyurethane copper-clad aluminum enameled wire is mainly composed of copper-clad aluminum metal wires and polyurethane paint coatings. Thanks to the copper layer on its surface and the specific paint film formula, welding can be carried out directly without the need to remove the paint film. This means that the operation steps can be simplified and production efficiency can be improved during the processing.

The characteristics of polyurethane copper clad aluminum enameled wire include:
1. Lightweight: The use of aluminum cores greatly reduces the weight of wires, making it suitable for applications with strict weight requirements.
2. Good conductivity: The copper layer on the surface of copper coated aluminum wire, provides good conductivity, making it suitable for applications that require current or signal transmission.
3. Excellent insulation performance: The polyurethane insulation layer has excellent electrical insulation performance, which can effectively prevent electrical short circuits.
4. Direct weldability
5. Diversity of colors in finished enameled wire products
