Enameled wire is the main raw material of electrical machinery, electrical appliances and household appliances. Especially in recent years, the electric power industry has achieved sustained and rapid growth. The rapid development of household appliances has brought a wide range of applications to copper enameled wire, with higher requirements for copper enameled wire.

Let's look at the mechanical properties of copper enameled wire:

In the process of winding enameled wire into a molded coil and embedded wire, enameled wire, clamp and enameled wire generate friction with each other and are subjected to bending, stretching or compression and other stresses. Therefore, the paint film of enameled wire is required to have good abrasion resistance, scratch resistance and good adhesion on the conductor. In order to facilitate manufacturing and processing, enameled wire is required to have good flexibility, elasticity and bending performance, so that the coil is not easy to deform after forming. Modern high-speed automatic winding machines also require enameled wires to have smooth surfaces and small friction coefficients, while enameled wires for special purposes require large friction coefficients. When the motor is running, the winding is impacted, vibrated, centrifugal force, thermal expansion and stress generated by overload, which requires enameled wire to have certain tensile strength.
