Enameled wire and copper wire as the electrical industry, two core conductive materials, although sharing high-purity copper substrate, but due to the structural design and process processing of differentiation, the formation of a “specialization” and “generalization” of the stark contrast.

In the core components of electromagnetic equipment such as motors, transformers, inductors, etc., the performance of enameled copper wire directly determines the efficiency, reliability and service life of the whole machine. Among the many performance indicators of enameled wire, the adhesion strength between the enamel film and the copper conductor is often overlooked but is a crucial core characteristic. It not only affects the smoothness of the production process, but also directly relates to the stability and safety of the equipment in long-term operation. In this paper, we will analyze the importance of film adhesion, factors affecting the practical application of value, to help industry practitioners to make more scientific selection decisions.

Learn key thermal classes, insulation materials & selection tips to choose the enameled wire for motors, transformers and high-temperature applications.
