<\/figure>\n\n\n\nThe use of electromagnetic wire can be divided into two types:<\/p>\n\n\n\n
\u2460 general purpose, mainly used in motors, electrical appliances, meters, transformers, etc., by winding the coil to produce the electromagnetic effect, using the principle of electromagnetic induction to achieve the purpose of conversion of electrical and magnetic energy;<\/p>\n\n\n\n
\u2461 special purpose, applied to electronic components, new energy vehicles and other fields with special characteristics requirements, such as micro-fine electronic wire is mainly used in the electronics and information industry to achieve the transmission of information, new energy vehicles special wire is mainly used in the production and manufacture of new energy vehicles.<\/p>\n\n\n\n
Enameled Wire<\/strong><\/p>\n\n\n\n Enameled wire is made by coating the conductor with a corresponding lacquer solution, followed by solvent evaporation and curing of the lacquer film and cooling. Enameled wire can be divided into polyester enameled wire, polyester imide enameled wire, polyamide imide enameled wire, polyimide enameled wire, polyester imide\/polyamide imide enameled wire, corona resistant enameled wire, as well as oil-based enamel, acetal enamel, polyurethane enameled wire, etc. according to the insulating lacquer used. Sometimes they are also classified according to the specificity of their use, such as self-adhesive enameled wire and refrigerant-resistant enameled wire.<\/p>\n\n\n\n Magnet wire<\/p>\n\n\n\n The earliest enameled wire is oil-based enameled wire, made of tung oil and so on. Its enamel film wear resistance is poor, can not be used directly in the manufacture of motor coils and windings, the use of cotton yarn wrapping layer. Later polyvinyl acetal enameled wire was introduced, its mechanical properties greatly improved, can be used directly for motor windings, and called high-strength enameled wire.<\/p>\n\n\n\n With the development of weak technology and the emergence of self-adhesive enameled wire, can be used without impregnation, baking and get a better overall coil. However, its mechanical strength is poor, and it can only be used in micro motors and small motors. In addition, in order to avoid the trouble of removing the varnish when soldering, direct soldering enameled wire has been developed, and its coating can come off by itself in the high-temperature tin bath and make the copper wire easy to solder.<\/p>\n\n\n\n As the application of enameled wire becomes more and more widespread and the requirements become more and more stringent, a composite enameled wire has been developed. The inner and outer enamel films are made up of different polymer materials, such as polyesterimide\/polyamideimide enameled wire.<\/p>\n\n\n\n Winding wire<\/p>\n\n\n\n One of the important varieties of winding wire. Early with cotton yarn and silk, called yarn-wrapped wire and silk-wrapped wire, had been used in motors and electrical appliances. Due to the large insulation thickness and low heat resistance, most of them have been replaced by enameled wire. At present, it is only used as high frequency winding wire. In the large and medium-sized specifications of the winding wire, when the heat resistance level is higher and the mechanical strength is greater, also use the glass wire wrapped wire, and in the manufacture with the appropriate adhesive lacquer.<\/p>\n\n\n\n In the winding wire paper wrapped wire still occupies a considerable position, mainly used in oil-immersed transformers. The oil-paper insulation formed at this time has excellent dielectric properties, and is inexpensive and long-lived. NOMEX paper wrapped wire is a winding wire made of oxygen-free copper rod or electrician round aluminum rod extruded or drawn by a certain specification die and then annealed on the copper (aluminum) conductor wrapped with two or more layers of insulating paper (including telephone paper, cable paper, high-voltage cable paper, inter-turn insulating paper, etc.) for oil-immersed transformer coils and other similar electrical winding wire. Round aluminum rod by a certain specification of the mold extrusion of the wire, and then by the United States DuPont NOMEX insulation paper wrapped winding wire, mainly for transformers, welding machines, electromagnets or other similar electrical equipment products winding. The extrusion process of the production of bare copper (aluminum) wire is the production of cable paper wrapped wire is the most ideal material.<\/p>\n\n\n\n In recent years, the more rapid development of film wrapping wire, mainly polyester film and polyimide film wrapping wire.<\/p>\n\n\n\n Recently, there are also used in wind power generation mica tape wrapped polyester imide film wrapped copper flat wire.<\/p>\n\n\n\n Insulated Wires<\/p>\n\n\n\n Inorganic insulating varnishes are usually used when the heat resistance level is required beyond the limits of organic materials. Existing inorganic insulated wires can be further divided into glass film wires, oxide film wires and ceramic wires.<\/p>\n","protected":false},"excerpt":{"rendered":" Inorganic insulating varnish is usually used for coating when the heat resistance rating requirements exceed the limits of organic materials.
