In the past few years, the domestic enameled wire market has been driven by traditional mechanical and electrical industries, emerging industries dominated by home appliances, high-tech industries with electronic information as the mainstay, and economic globalization. Promote the continuous rapid development of the enameled wire industry. Since 2003, the supply and demand of China's enameled wire has surpassed Japan and the United States, becoming the world's largest producer.

Due to the rise in copper prices and sharp fluctuations, the enameled aluminum wire has developed, and the domestic enameled aluminum wire production capacity has reached

3-4 tons.

Due to the unique characteristics of aluminum wire, enameled aluminum wire is mainly used in those intermittently operated electrical equipment and electrical products with low power and low requirements on the size of the windings; in the following table a detailed display of enamelled round aluminum wire in China The main application areas and types of paints used and the main product types and main features of electric insulation.

Like the development of enamelled round copper wire, the development of aluminum wire is also largely dependent on the development of enameled wire lacquer and the ever-increasing performance and cost requirements of terminal electrical equipment customers.

This is very obvious in the microwave transformer industry. Microwave oven transformer industry is the industry with the largest demand for enamelled round aluminum wires. The insulation systems used by the vast majority of current microwave oven transformer manufacturers are 220-level insulation systems from the United States and South Korea. In this special industry where each transformer has only 2.3 yuan or even 1 yuan profit, the proportion of enamelled round aluminum wire in the material cost of a single transformer is very large (about 40%), reducing the size of the transformer and reducing the enameled wire The amount used to increase the thermal rating of the transformer insulation system is the only choice to reduce costs.
