Introduction

The diameter of each single wire of the enameled copper wire is 0.14mm, which is very thin and soft, and can well adapt to various complex bending or deformation configurations. In addition, the enamelled copper wire also has good corrosion resistance and high temperature resistance, and the single wire temperature resistance grade is 180 degrees, which is suitable for various high temperature environments.

At the same time, the enamelled copper wire is coated with polyurethane, which can ensure that its surface is smooth, not easy to be damaged by friction, and its electrical performance is also very stable. In addition, the enamelled copper wire can also be directly welded, making it more convenient and quick.
