Direct welded Triple Insulated Litz Wire TIW-L-B/TIW-L-F/TIW-L-H

Triple insulated wire, also known as triple insulated wire, is a new high-performance insulated wire developed internationally in recent years. This wire has three layers of insulation with the core in the middle.

The first layer is a golden-yellow polyamide film, which is called "gold film". Its thickness is several microns, but it can withstand a pulsed high voltage of 1kV; the second layer is a high-insulation paint coating; The layer (outermost layer) is a transparent fiberglass layer. The total thickness of the insulating layer is only 20-100 Å.

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 winding, the coil can be automatically formed after 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.
