In 2016 our country enameled wire industry development situation and characteristics of the analysis (figure)
Enameled wire is electromagnetic wire (that is, the winding wire), is an insulating layer of conductive metal wires, in the form of winding produce electromagnetic effect, realizes the electric and magnetic energy conversion, the purpose of the motion control and signal transmission, consists of two parts, conductor and insulation layer, bare wire after annealing softening, and after a lot of paint, baking, general mechanical properties, chemical properties, electrical properties and thermal properties of four performance. At present, enameled wire dominated in the winding line.

Human first use enameled wire was in 1831, the famous physicist Faraday application enameled wire manufacturing electromagnetic induction coil, the famous electromagnetic induction test, thus established the theory of electromagnetic induction. As the electromagnetic induction theory founded in 1866, Siemens generator invention, 1877, Edison invented the electric light and transformer, solves the problem of long-distance transmission of electricity. Then Gregory's invention of the electric motor, electrical energy and mechanical energy transformation, power soon get extensive application, produced by electricity used for signs of the second industrial revolution.

First, the second industrial revolution the British economy rise, in the UK has a BICC, leads the world manufacturing technology, during the second world war ii invented the catalytic combustion technology and the mold coating technology, trigger a significant change of enameled wire, then transfer the technology to the ESSEX company in America. After world war ii with the rise of the us economy, drive the economic development of the whole Western Europe and the americas, formed a u.s.-led economic power. Enameled wire in these areas with the rise of the us-led economy, the improvement of technical level of industrialization, the variety of enameled wire, the production and business operation scale, a huge manufacturing industry development, has created the world the first generation of enameled wire industry leading enterprises in the United States. Such as the United States of Essex, inc., Philip. Dodge company, France's alcatel company, from the varieties of products, manufacturing technology, production capacity has reached the international advanced level in the scale of operation, etc., and the comprehensive development of enameled wire industry all over the world.
In the 1960 s, the rise of the Japanese economy, especially in the rapid development of home appliance industry development as the logo, and lead the world's advanced level, drive the development and application of new varieties of enameled wire. Adhesive enameled wire, high temperature resistant, resistant to cold media enameled wire enameled wire composite enameled wire, such as scale, or manufacturing technology in the world, promote the enameled wire industry into a new stage. This period has created the world enameled wire industry enterprises in Japan in the second generation of leaders. Such as Japan's first electrician, good friends, and Japan Hitachi electrical wiring, South Korea's LG company, the company the scale of operation of compound line, manufacturing technology and quality level in the world advanced level, the sustainable development of leading industry.
The 21st century, the world economy, great changes have taken place. As China's economic rise, especially after China's accession to the WTO, China's economy into the global economy, the world's manufacturing industry to speed up the transfer to China, make China become the world manufacturing base, driving the development of high-speed enameled wire industry in China, in terms of scale has become the world's first production power.
International enameled wire enterprises are classified into large industrial groups and professional engaged in two kinds of enameled wire industry. Internationally influential mainly has five manufacturers: Alcatel Alcatel electromagnetic wire co., Essex Essex electromagnetic wire co., Phelps dodge PhelpaDodge electromagnetic wire co., in the REA electromagnetic wire and HLCC le Elaektrisola group company.

Along with the transfer of the world's manufacturing center and the formation of China to become the world manufacturing center, enameled wire markets around the world began to gradually shift to China, at the same time, the benefit from the mechanical and electrical, home appliances and other electronic information technology industry, as the main body of the high-tech industry and the factors such as joint driven by economic globalization, the enameled wire industry keep high speed development of our country, enameled wire production has exceeded the United States and Japan and other countries, to become the world's largest producer and consumer.
In addition, with the opening up of the Chinese market and the world manufacturing transfer, household appliances, electronic information, communication products, electric tools, such as export growth, drive the enameled wire industry on a large scale to enter the international market and maintain a comprehensive growth, number of China's customs statistics show that in recent years, China's exports of enameled wire in rising steadily, import quantity decline year by year.
According to the statistics: enameled wire industry in China in 2005 the annual output of 907000 tons, to the industry output growth in 2014 to 1.66 million tons, annual output of 1.745 million tons, 2015 enameled wire production in our country in recent years, the average annual growth rate of 7.0%.
