ISO/UL system Certificated Three-Layer Insulated Winding Wire

Three-layer insulated wire is suitable for cutting-edge technology and national defense fields, making micro-motor windings, and high-frequency transformer windings for miniaturized switching power supplies.

Its advantages are high dielectric strength (any two layers can withstand a safe voltage of 3000V AC), no need to add barrier layers to ensure safe margins, and no need to wrap insulating tape layers between stages; high current density.

The volume of the high-frequency transformer wound with it can be reduced by half compared with that of the enameled wire. The texture of the three-layer insulated wire is tough, and it needs to be heated to 200-300 ° C to become soft and wound. After the winding is completed, the coil can be automatically formed after being cooled.

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 23 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.
