Enamelled copper wire

Enamelled copper wire is a major type of winding wire, consisting of two parts: a conductor and an insulation layer. The bare wire is annealed and softened, then painted and baked multiple times. However, it is not easy to produce products that meet both standard requirements and customer requirements. It is influenced by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires vary, but they all have four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties.

Enamelled copper wire is the main raw material for products such as motors, appliances, and household appliances. Especially in recent years, the power industry has achieved sustained and rapid growth. The rapid development of household appliances has brought a wider range of applications for enameled wire, which has led to higher requirements for enameled wire. Therefore, it is inevitable to adjust the product structure of enameled wire, and the matching raw materials (copper, paint), enameling process, process equipment, and testing methods also urgently need to be developed and researched.

At present, there are over a thousand manufacturers of enameled wire in China, with an annual production capacity of over 2.5-3 million tons. But overall, the situation of enameled wire in China is a low-level repetition, which can be summarized as "high production, low grade, and outdated equipment". In this situation, high-quality enameled wires for household appliances still need to be imported, let alone participate in international market competition. Therefore, efforts should be doubled to change the current situation, so that China's enameled wire technology level can keep up with market demand and squeeze into the international market.
