Enameled wires belong to a category of magnet wires and generally refer to insulated wires used to manufacture coils or windings in electrical products. Also called winding wire.

Aluminum Magnet Wire must meet the requirements of various applications and manufacturing processes. The former includes its shape, specification, ability to work at high temperature for a short time and a long time, as well as withstanding strong vibration in some occasions and centrifugal force at high speed, corona and breakdown resistance under high voltage, chemical corrosion resistance under special atmosphere, etc. The latter includes the requirements of stretching, bending and abrasion during winding and embedding, as well as swelling and erosion during impregnation and drying.

Magnet wires can be classified according to their basic composition, conductive wire core and electrically insulating layer. Generally, it is divided into enameled wire, wound wire, enameled wound wire and inorganic insulated wire according to the insulating material and manufacturing method used for the electrical insulating layer.

The enameled wire is prepared by coating the conductor with corresponding paint solution, volatilizing the solvent, curing the paint film and cooling. Enameled wires can be divided into polyester enameled wires, polyester-imide enameled wires, polyamide-imide enameled wires, polyimide enameled wires, polyester-imide/polyamide-imide enameled wires, corona-resistant enameled wires, as well as oily paints, acetal paints, polyurethane enameled wires, etc. according to the insulation paint used. Sometimes it is also classified according to the particularity of its application, such as self-adhesive enameled wire, cryogen-resistant enameled wire, etc.

Due to the increasingly wide application of enameled wires and the increasingly strict requirements, composite enameled wires have also been developed. The inner and outer paint films are made of different polymer materials, such as polyetherimide/polyamide-imide enameled wire.
