The coil composed of enameled wire in a transformer is an extremely important part of the structure of the transformer. The enameled wire produced by Jingda is coated with a uniform layer of enamel film on the surface of copper wire using precision technology. Depending on coating materials, they can be divided into different types of enameled wire such as UEW(polyerethaneenameled wire), UEW-NY (polyurethane nylon enameled wire), PEW (polyester enameled wire), EIW (polyester-imide enameled wire), AIW polyamide-imideenameled wire) and other different kinds of enameled wire, which are used for different purposes.
Among these types, UEW and UEW-NY can be directly soldered, and Jingda usually provides temperature grades of F and H. In the case of excellent mechanical and chemical properties, UEW-NY has higher wear resistance, making it suitable for single wire multi-coil winding. As far as the enamel film thickness is concerned, Jingda commonly uses Japanese standards such as 1UEW, 2UEW and 3UEW. The enamelfilm thickness is reduced in sequence for different application fields and machine models.
At the same time, in order to meet the needs of large wire diameters, UEW wire is commonly used to make litz wire, fiberglass wrapped wire and film wrapped wire. Litz wire is to wind multiple conductors together to reduce skin effect and ensure uniform power transmission, thereby ensuring efficient operation of power equipment. The advantage of film wrappedwire is that it is resistant to high temperature and high pressure, but it requires additional peeling of the film before soldering. The advange of fiberglass wrapped wire is that it can protect the wire during the winding process and can be directly soldered.
In addition, PEW, EIW and AIW produced by Jingda have extremely high wear resistance and scratch resistance, and are often used in the production of various inductors and other power equipment. The commonly used temperature grades for PEW are F and H, and the prices are relatively economical, which is highly favored by many long-term cooperative customers. EIW and AIWs’ temperature resistance can usually be up to 200 degrees and 220 degrees, heat shock and chemical corrosion resistance are excellent, and are often used in high-performance products such as shaped wire inductors. All of them can be customized according to customer needs.
In all, different types of enameled wires that can be used for transformers have different characteristics. As a trusted manufacturer of enameled wire, Jingda can provide a variety of enameled wire products, always providing thoughtful service and practical products to customers, and helping to manufacture the highest quality transformers with the most reliable enameled wires.
