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 ...
