rectangular enameled wireis one of the main varieties of winding wire, which consists of two parts: conductor and insulating layer. After the bare wire is softened by annealing, it is painted and baked many times. However, it is not easy to produce products that not only meet the requirements of the standard, but also meet the requirements of customers. It is affected by the quality of raw materials, process parameters, production equipment, environment and other factors. Therefore, the quality characteristics of various enameled wires are different, but they all have Mechanical properties, chemical properties, electrical properties, and thermal properties are four major properties.
Rectangular enameled wire is the main raw material for products such as motors, 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 broader field to the application of enameled wires. It puts forward higher requirements for enameled wire. For this reason, the product structure adjustment of enameled wire is inevitable, and the matching raw materials (copper, paint), enameling process, process equipment and testing methods are also in urgent need of development and research.
At present, there are over 1,000 manufacturers of rectangular enameled wire in my country, with an annual production capacity of over 250,000 to 300,000 tons. But in general, the status of rectangular enameled wires in my country is a low-level repetition, generally speaking, “high output, low grade, and backward equipment.” In this situation, high-grade enameled wires for high-quality home appliances still need to be imported, let alone participating in international market competition. Therefore, we should redouble our efforts to change the status quo, so that our country’s enameled wire technology level can keep up with market demand, and squeeze into the international market.
