UEW 155 0.011mm Ultrafine Magnet Winding Wire Enameled Copper Wire For Motor / Transformer
We are one of the pioneers in producing micro thin enameled wires below 0.03mm in China. Our R & D team has 20 years of market experience.We have achieved the goal of "zero pinholes after stretching" for ten years. In 2019, our finest diameter is 0.011mm, and mass production has been achieved.When the displays return the transformer industry, we are the No.1 Chinese brand with a share of cake.We rival the internationally renowned enameled wire brands for production, technology, raw materials.We surpass them in terms of "service, quick response"; 30% lower "price" is our advantage. More and more well-known customers choose us as suppliers-Philips, Bosch, Panasonic, Samsung ...
We have a long history of producing self-adhesive lines. Since the beginning of our factory, we have started to develop and produce self-adhesive lines. Because of our strong R & D strength, our products have a wide range of applications.We have a full range of self-adhesive lines and a wide range of applications.Thermal class is155C, 180 C, 200 C, 220 C. Conductor material includes enameled round wire, enameled copper-clad aluminum wire.
