Class 155 Enameled Magnet Wire


Polyurethane Enamelled Winding Wire

Product Description

0.012mm - 0.08mm Class 155 Polyurethane Ultra Thin Enameled Copper Wire For Motor Winding

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 assuppliers-Philips, Bosch, Panasonic, Samsung ...
