UL Certificate UEW Ultra Fine Enameled Copper Winding Wire Self
Bonding Wire 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, 180C,
200 C, 220 C. Conductor material includes enameled round wire, CCA
