In the previous article, I briefly outlined the classification of some enameled wires, and then we continue with the introduction of the remaining parts of the classification. Enameled Copper Wire is a main type of winding wire. It is composed of a conductor and an insulating layer. After the bare wire is softened by annealing, it is painted and baked many times.

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. Higher requirements are put forward for enameled wire.

5) Polyimide enameled wire

Polyimide is currently the highest heat-resistant enameled wire paint among organic enameled wires, and its long-term use temperature can reach 220°C or more. The paint was successfully developed by the United States in 1958. Polyimide enameled wire has high heat resistance, good solvent and refrigerant resistance. However, due to its high cost, poor storage stability and toxicity, it has affected its widespread use. At present, the enameled wire is used in some special occasions, such as wires used in coal mine motors, space instruments and meters.

6) Polyamide-imide paint

Polyamide-imide paint is the most comprehensive in the current enameled wire paint, with high heat resistance, mechanical properties, refrigerant resistance and chemical resistance, so it is known as the king of enameled wire paint. The paint is currently mainly used for its unique properties, and is widely used as the top coat of composite coated enameled wires to improve the heat resistance of composite wires and reduce costs. At present, it is mainly used to coat refrigerant-resistant enameled wire in China. This paint is produced in a small amount in China, mainly imported from the United States, Italy and Germany.

7) Composite coating enameled wire

To improve the temperature resistance level and develop special-purpose enameled wires, composite insulation layers are generally used. Compared with single-coated enameled wire, composite coated enameled wire has the following advantages: (1) It meets special requirements, such as self-adhesive enameled wire for complex frameless forming, refrigerant-resistant enameled wire for refrigerators and air-conditioning compressors, etc., can pass composite coating Structure to meet; (2) through the composite of various insulating layers to make up for their strengths, improve and improve the use performance to meet the requirements of use, such as polyester/nylon composite coating enameled wire to improve the thermal shock performance and winding performance, suitable The hot dipping process can be used for motor windings with instantaneous overheating due to overload; (3) It can reduce the cost of some enameled wires, such as polyester imide and polyamide-imide composite coated enameled wires instead of single-coated enameled wires. Polyamide-imide enameled wire can greatly reduce costs.
