5.00mm Class 220 rectangular enameled copper wire for motor winding

This custom-made wire SFT-EI/AIW 5.00*0.20 is 220°C Polyamideimide composite polyesterimide copper flat wire. The customer uses this wire on the power transformer. It has been using round enameled wire, In order to solve the bottleneck problem of coil performance, make the resistance smaller and the capacitance larger to meet the requirements of large capacitance and high load application scenarios.

We offer this flat wire. With the advancement of science and technology, in the past, the use of round enameled wire had poor heat dissipation, large coil size, and low power. With the development of high-end equipment, the enameled wire is required to be wide and flat for vertical winding, so as to achieve many advantages such as heat dissipation for each wire, high slot full rate, small product size and high power.

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.
