0.025mm 180℃ SEIW Polyester-imide Solderable Insulated Round Enameled Copper Wire

SEIW wire is an enameled copper wire with polyester-imide insulating layer. The temperature resistance grade is 180℃. Insulation of SEIW can be soldered directly without removing the insulating layer by manual or chemical methods, it make the soldering process simple, reduce the manufacturing cost and improves the efficiency. In addition,it has high temperature resistance, good adhesion of insulation layer and conductor, meet the requirements of winding that soldering and high heat resistance.

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.
