Insulated wires used to manufacture coils or windings in electrical products. Also known as winding wire. Electromagnetic wires must meet various requirements for use and manufacturing processes. The former includes its shape, specifications, ability to work at high temperatures for short and long periods of time, as well as withstanding strong vibrations in certain situations and centrifugal forces at high speeds, withstanding corona and breakdown at high voltages, and resisting chemical corrosion in special atmospheres; The latter includes the requirements for withstanding tension, bending, and wear during winding and embedding, as well as the swelling and erosion effects during impregnation and drying processes. Electromagnetic wires can be classified according to their basic composition, conductive core, and electrical insulation layer. Usually, the electrical insulation layer is divided into enameled wire, wrapped wire, enameled wrapped wire, and inorganic insulation wire based on the insulation material and manufacturing method used
