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
