What Makes Enameled Wire Different From Others


    It is made by smearing the relative paint aqueous solution on the electric conductor, and then the organic solvent is evaporated and the paint film is dried and cooled. Enameled wire can be divided into polyester enameled wire, polyester imide enameled wire, acrylic resin imide enameled wire, polyimide film enameled wire, polyester imide/acrylic resin imide enameled wire, and corona discharge resistance according to its commonly used insulating paint. Enameled wire, oil paint, acetal paint, polyurethane material enameled wire, etc. Sometimes it is also classified according to the uniqueness of its main purpose, such as self-adhesive enameled wire, refrigerant resistant enameled wire, etc.

    The first enameled wire was oil-soluble enameled wire, made of tung oil. The paint film has poor abrasion resistance and cannot be used immediately to produce electromagnetic coils and windings for motors. It is necessary to add a pure cotton yarn wrapping layer during application. Afterwards, formaldehyde enameled wires in acrylic emulsion shrinkage chambers were launched, and their mechanical equipment performance was greatly improved, and they could be used for motor winding immediately. With the development trend of weak current installation technology, there appeared self-adhesive enameled wires, which can be comprehensive without pre-impregnation and cake baking. Good electromagnetic coil. But its impact toughness is weak, and it can only be used in micro motors and small motors. In addition, in order to better prevent the inconvenience of prioritizing the removal of paint film during electric welding, the development trend o Enameled Aluminum Wire, whose coating can automatically fall in the high temperature tin bath, makes the copper core wire very easy to weld.
