Product Description

0.18mm Polyurethane Winding Wire Enameled Copper 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 ...


Advantages Of Enameled Copper Wire

  1. a) High resistance to heat shock.

  2. b) High temperature.

  3. c) Good performance in cut-through.

  4. d) Suitable for high-speed automated routing.

  5. e) Able to be direct weld, with no pinhole.

  6. f) Resistive to high frequency, wearing, refrigerants and electronics corona.

  7. g) High breakdown voltage, small dielectric loss angle.

  8. h) Environment-friendly.
