0.15mm Fully Insulated Zero-Defect Enameled Round Copper Wire FIW Wire Copper conductor solid

FIW (Fully Insulated Wire) is an alternative wire to build switching transformers typically using TIW (Triple Insulated Wires). Due to the big choice of overall diameters it allows to produce smaller transformers at lower costs. At the same time FIW has better windability and solderability compared to TIW.

RUIYUAN was established in 2002, located in Tianjin City,the second largest port city in China.We have been focusing on different kinds of high quality wires: enameled round copper wire, rectangular enameled copper triple insulated wire, silk covered Litz wire, bonding wire and special enameled wire for 21 years.Ruiyuan is 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. In 2019, our finest diameter is 0.011mm, and mass production has been achieved. All of our products are UL, RoHS certified, in line with industry standards IEC60317, JIS C 3202, NEMA, NW82.
