0.02mm Magnet Wire

Product Description

Class 155 / 180 /220 0.02mm Magnte Wire Ultra Fine Copper Wire Enamel For Transformer


The conductor is the basic material of the enameled wire. Commonly used materials for conductors are copper, aluminum and other alloy materials. Usually the resistance in an electronic component is determined by the conductor. The cross-sectional area and length of the conductor affect the resistance.The insulating film is divided into single film and heavy film. Single film includes UEW, PEW, EIWHE AIW etc. Heavy film refers to an additional coating of nylon or self-adhesive paint on a single film.

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, Bosch, Panasonic, Samsung ...

Advantages Of Enameled Copper Wire

a) High resistance to heat shock.

b) High temperature.

c) Good performance in cut-through.

d) Suitable for high-speed automated routing.

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

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

g) High breakdown voltage, small dielectric loss angle.

h) Environment-friendly.
