AIW / UEW Class 180 / 220 Super Thin Rectangular Enameled Copper Wire

Made of exygen free copper with rectangular shape.

Modern Enameled Copper Magnet Wire typically uses one to three layers of polymer film insulation, often of two different compositions, to provide a tough, continuous insulating layer. Magnet wire insulating films use (in order of increasing temperature range) polyvinyl formal or Formvar (PVF), polyurethane, polyamide (PUW), polyester (PEW), polyester-polyimide (EIW), polyamide-polyimide (or amide-imide) (AI-EIW), and polyimide (AIW). Polyimide insulated magnet wire is capable of operation at up to 250°C. The insulation of thicker square or enamelled rectangular aluminium or copper magnet wire is often augmented by wrapping it with a high-temperature polyimide or fiberglass tape, and completed windings are often vacuum impregnated with an insulating varnish to improve insulation strength and long-term reliability of the winding.

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.
