FIW4 0.3mm 5300V Enameled Copper Wire FIW Wire For Transformer Winding

Fully insulated (FIW) zero-defect enamelled round copper wire is the wirewith highthermal class, Zero-defect strengthened insulation and highvoltage resistance compliance with IEC60317-56 / IEC60950U and NEMAMW85-C. FIW is an alternative wire to build electronic transformerstypically using TIW (Triple Insulated Wires)The wire can meet therequirements of miniaturized components,good winding performance andlow cost, applied small transformer, electronic switch etc.

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.
