Incarnations of enameled wire products overview and history

Enameled wire winding line is one of the main types, are made conductive filling metal conductor, exterior coating polymer insulation layer, mainly consists of two parts; Is electromagnetic energy into mechanical energy, heat energy, sound energy, light energy, or mechanical, thermal, chemical, such as sound, light energy is converted into electromagnetic energy functional materials. Is industrial motor (including motor and generator), transformers, electrical instrumentation, electrical and electronic components, electric tools, household appliances, automobile electrical appliances for the main material of electromagnetic coil winding. Enameled wire conductor section is generally the annealing treatment of doping of pure metal, such as copper, aluminum, some cases also use copper alloy, gold, silver, nickel, stainless steel and other materials, according to different working voltage and working temperature, the enameled wire is often used in AN ester, such as polyester, polyester imide, polyimide polymer used as insulating film material in metal wire winding solenoid coil. Enameled wire classification has a lot of kinds, main classification is as follows:

Enameled wire are copper rod upstream, downstream is all kinds of consumer terminal, mainly motor and transformer. Enameled wire is a kind of winding line (electromagnetic wire). The winding wire is a kind of insulating layer of conductive metal wire, wire to the coil windings or electrical products. Its action is produced by current magnetic field, or cutting lines produce induced current, achieving mutual transformation of electric and magnetic energy, so it is also called electromagnetic wire. Winding wire of conductive wire core round wire, flat wire, belt, foil, etc., at present most use copper wire, also some use aluminum wire, in order to improve the tensile strength of aluminum winding wire, can be used high conductivity, high strength aluminum alloy, etc. Winding line according to the characteristics and purposes of the insulating layer, can be divided into enameled wire, insulated wire around, special insulation winding line three categories. Silk covered wire around the package including: paper, glass, film around the envelope, submersible motor with special around the envelope, wind turbines with winding wire, wire single wire, wire cable, transposed conductor; Special winding line: refers to suitable for special occasions or with special performance requirements of the winding line.

Enameled wire production process mainly includes: pay-off, annealing, painting, baking, cooling, take-up. Pay-off is on normal operation of a paint charter pay-off, operators in order to reduce energy and energy loss, usually adopt large capacity pay-off, pay-off is the key to control tension, wants even appropriate. At the same time, the pay-off device of wire of different specification with different, large size large capacity generally USES the radial rotary spool pay-off; The more commonly used medium specifications wire end type or brush type pay-off; Subtle commonly used specifications wire brush type or double taper sleeve type feeding device. Steel after annealing, the purpose of annealing is to disrupt the molecular lattice structure, makes the pay-off harden conductor in the process of after a certain temperature of heat recovery process requirement of softness, at the same time to remove the lubricant in drawing process, oily be soiled, ensure the quality of the enameled wire. After annealing for painting, painting is the enameled wire paint Shanghai juji evenly in the thickness of the metal conductor to form a certain process of lacquer layer. Different coating methods, different wire specifications different demands on the viscosity of the paint. General enameled wire, goes through many Shanghai juji and baking process to make the solvent evaporation, fully painted resin reaction completely, form good film. Baking and paint, also is a cyclical process, will first paint solvent evaporation in the liquid, and then curing, forming a layer of paint film, and then paint baking. Generates pollutants in the roasting process, must immediately ruled out furnace, catalytic combustion is commonly used in hot air circulation oven, at the same time, quantity of waste neither too big nor too small, because waste process will take a lot of calories, so waste is to ensure the safety in production and product quality, and can't lead to the loss of a large amount of heat energy. Out of the oven enameled wire, high temperature, paint film is soft, strength is very small, if not timely cooling, through the idler pulley film damage, affects the quality of enameled wire. Line line, cooling of the next step is to gather the enameled wire is the purpose of continuous, compact, uniform winding to the spool. Take-up machine is stable, low noise, appropriate tension and neat rows.

Enameled wire production live diagram is as follows:

Enameled wire industry has a long history, from the earliest can be traced back to 1831 Faraday electromagnetic induction experiment, when the first human to enameled wire used in the manufacture of electromagnetic induction coil, Siemens and Edison subsequently invention motors, lights and transformers, the invention of the motor and transformer can solve the problem of electric transport, the application of the enameled wire prelude to open.

Enameled wire change period began in the second industrial revolution, during the catalytic combustion technology and mold coating technology invention, after the second world war as the U.S. economy rise, greatly promoted the development of the enameled wire industry, makes the enameled wire varieties, production and operation scale, manufacturing technology to improve, in the meantime also gave birth to the first generation of enameled wire leading enterprises, such as the United States Essex, philippe dodge, alcatel of France, and lead the world enameled wire industry development.

In the 1960 s, Japanese industrial economy led to the rise of enameled wire industry a new round of development, the technology of enameled wire industry is a new wave of ascension, mainly is the rise of home appliance industry, drive the development of special enameled wire, enameled wire, such as adhesive refrigerant resistant enameled wire, the development of compound such as high-temperature enameled wire enameled wire, etc. During this period has formed the second generation of enameled wire leading enterprises, mainly the first electrician, Japan's sumitomo, Japan Hitachi electrical wiring, south Korean LG company, etc., leading the world high-end enameled wire.

Change after the 21st century, the world economy, China's economic rise, especially after China's accession to the WTO, China's rapid economic growth, to become the world manufacturing base, makes the enameled wire needs a large number of growth, China's huge demand for enameled wire size, enameled wire production and consumption has become the first big country, and foreign well-known enterprises have set up manufacturing base in China, the advanced production technology, the development of the enameled wire provides a good international environment.

Enameled wire application field is very broad, mainly motor and transformer industry, different types of enameled wire application fields are also different, in addition to the motor and transformer industry, home appliance is also an important application field of enameled wire, special enameled wire, enameled wire in recent years, the car for demand is very big also, especially the new energy vehicles, is one of the important application of enameled wire terminals.
