Product Description

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" in foreign countries. 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.


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 a barrier layer to ensure a safe margin, and no need to wrap the insulating tape layer, and the current density is high. 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 cooling

The three-layer insulated wire is especially suitable for winding high-frequency transformers in miniaturized, high-efficiency switching power supplies. Taking the high-frequency transformer using TEX-E as an example, because the interlayer insulating tape is omitted, and there is no need to add a barrier layer, it is 1/2 smaller than the traditional transformer wound with enameled wire, and the weight is approximately reduced. 1/3, which can greatly save material and processing costs. In view of the high price of the three-layer insulated wire, it is especially suitable for winding the secondary winding of the high-frequency transformer of the miniaturized switching power supply, while the primary winding and the feedback winding are still wound with ordinary enameled wire.
