Summary of the development of enameled wire technology
The enameled wire consists of a conductor and an insulating layer. After the wire is softened by annealing, it is painted and baked many times. It is an important electronic special material with a wide range of applications. The article summarizes the development of enameled wire technology.
Enameled wire is a kind of electromagnetic wire (ie, winding wire). It is a conductive metal wire with an insulating layer, which produces electromagnetic effects in the form of windings to realize the conversion of electric energy and magnetic energy, action control and signal transmission. The enameled wire consists of a conductor and an insulating layer. After the bare wire is softened by annealing, it is painted and baked many times. Depending on the working voltage and working temperature, enameled wires are usually made of polyurethane, polyester, polyesterimide, polyimide and other polymers as insulating film materials for the metal wires of electromagnetic coils. Enameled wire generally has four major properties: mechanical properties, chemical properties, electrical properties and thermal properties. At present, enameled wire occupies a dominant position in windings. The article summarizes the development of enameled wire technology.http://mag.big-bit.com/news/323688.html
