0.028mm – 0.05mm Ultra Thin Enameled Magnet Winding Copper Wire

We have been specializing in production of enameled copper wires over two decades, and have made great achievements in the field of fine wires. The sizes range starts from 0.011mm that represent the most advanced technology and best material. Geographical distribution of our customers is all over the world, mainly in Europe. Our enameled copper wire is widely used in different fields, such as medical device,detectors, high and low frequency transformers, relays, micro motors, ignition coils Here we bring you the size range that is used in most applications. 0.028-0.050mm Among them G1 0.028mm and G1 0.03mm are chiefly winded for the secondary high-voltage transformers. G2 0.045mm,0.048mm and G2 0.05mm are chiefly applied to ignition coils. G1 0.035mm and G1 0.04mm are chiefly applied to relays Requirements of enameled copper wire for different applications vary even for the same enameled copper wire. For example, withstand voltage is very important to magnet wires for ignition coils and high-voltage transformers. The thickness of enamel needs to be stringently controlled to ensure that withstand voltage meets requirements. To ensure consistency of outer diameter, we adopt the method of multiple times of thin enameling. For relays, thinly enameled copper wire is usually applied as stability of the conductor resistance is vital to them. This requires us to pay great attention to select raw material and wire drawing process. Our regular test items of enameled copper wire are as follows: appearance and O.D Elongation Breakdown voltage Resistance Pinhole test(we can achieve 0)
