The W 21 of the round enameled wire conforms to the standard EN 13601Cu-ETP copper conductor, and the inner ring of polyester (imide) and the outer layer of polyamide-imide are used as winding wires made of insulating materials.

The heat resistance of W 210 enameled wire is the high heat resistance of 200 enameled wire. The polyamide-imide insulating layer has good durability and thermal stability, and at the same time has a very small surface friction coefficient, so it has excellent mechanical wear resistance. In addition, it has excellent chemical resistance, such as alkalis, washing powders, detergents and dipping-injection-casting materials, thinners, solvents, refrigerants and steam. Check the compatibility with special materials during use. After the connection is peeled off by tin, it is directly bonded, soldered, crimped, etc.

Excellent performance makes W 210 enamel paint a comprehensive application, requiring high corrosion resistance, high processability or high reliability in various fields. It is also widely used in motors, generators and transformers of different sizes, especially in areas with special requirements for machinery and chemistry, such as refrigerators.
