SWG / AWG Submersible Winding Wire Enamelled Copper Wire for Motor Winding

In practice, maximum current density can vary from 2.5 A/mm² for a wire isolated from free air to 6 A/mm² for a wire in free air.If the wire is carrying high frequency currents (above 10 kHz), the skin effect may affect the distribution of the current across the section by concentrating the current on the surface of the conductor.

If active cooling is provided by blowing air or circulating water, then much higher current densities can be achieved - proportionally to the effectiveness of cooling.

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.
