The Splicing Method of Magnet WiresThe Splicing Method of Magnet Wires

Magnet wires is used to wind motos and transformers. No matter for rewinding or repairing, the conductors need to be splicing. Let’s get to know the three different basic joint method of winding wires.

Technology Development Direction and Market Trends of Medium and Small Sizes and Ultra Fine Enameled WireTechnology Development Direction and Market Trends of Medium and Small Sizes and Ultra Fine Enameled Wire

According to statistics from relevant professionals and industrial survey data, at present, the demand of enameled wire in our country is about 600,000 tons, and it is estimated that it will reach to 1.1 million tons at the end of the 11th five-year plan, of which the enameled wire with medium and small sizes accounts for about 45%. The main application areas are small appliances, automotive motors, power tools, communications, electronic information and micro-motor industries. With the increase of product categories in these industries, the continue upgrading of products, many types of electronic components have higher requirements on the varieties and quality of enameled wire used. In addition to further improve on four major performance indicators of common used enameled wire, but also added many special features to meet specific functional requirements, or to improve applicability and reduce enameled wire production cost. Such as: thinning, lightweight, high self-adhesive, tension characteristics, consistency of winding parameters, high frequency and high pressure characteristics, high Q value characteristics, thermal fusibility, heat resistance, refrigerant resistance, shaped, non-magnetic, high conductivity and so on. The development of enameled wire technology also put forward higher requirements on production process management, such as production technology, production equipment, personnel quality, production environment, testing methods and materials applications

Influence of Conductor Material and Enameled Paint on the Quality of Enameled WiresInfluence of Conductor Material and Enameled Paint on the Quality of Enameled Wires

Conductor material It is well-known that the production of magnet wire requires the use of high-quality copper, which is more important for enameled wire production. However, the commonly used oxygen-free copper rod and the electro-mechanical toughening copper rod have different drawing and annealing characteristics due to different manufacturing technologies. High flexibility of the electromagnetic wire products recommended for the use of electrical tough pitch rod as conductor material. Although the importance of conductor quality has been recognized by more and more enterprises, but the rational use of drawing equipment, lubricant continuous monitoring, mold matching, maintenance and other aspects are far less than the follow-up process as much emphasis on. Foreign studies have shown that the surface quality of the enameled wire and paint film continuity defects caused by 10% of the reason from the copper Drawing process, which is sufficient to demonstrate the importance of applied research on conductor materials.
