The conductor is the basic material of the enameled wire. Commonly used materials for conductors are copper, aluminum and other alloy materials. Usually the resistance in an electronic component is determined by the conductor. The cross-sectional area and length of the conductor affect the resistance.The type of insulating film: The insulating film is divided into single film and heavy film. Single film includes UEW, PEW, EIWHE AIW etc. Heavy film refers to an additional coating of nylon or self-adhesive paint on a single film.Magnet wire has excellent mechanical, electrical and chemical performance, especially in high current output, heat resistance and corrosion resisitance.t is mainly used in high-voltage transformers, electric machines, generator, etc. A special type of enamelled wire is self bonding or adelaide enameleld wire.
