product name	triple insulated wire (single core)
product material	Pure copper enameled wire/PET polyester
Product color	Default (earth yellow) other colors can be customized
Specification range	0.13mm-1.0mm pure copper diameter without paint layer
Product Description	This type of wire has three layers of insulation with a core wire in the middle. The first layer is a golden polyamide film with a thickness of a few microns, but it can withstand a pulse high voltage of 1kV; the second layer is a highly insulating paint coating; the third layer (the outermost layer) is 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 insulation 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 wind an insulating tape layer between stages; the current density is high. The volume of the high-frequency transformer wound with it can be reduced by half compared with that wound with enameled wire. The texture of the three-layer insulated wire is tough, and it needs to be heated to 200-300°C to soften and wind. After the winding is completed, the coil can be automatically formed after being cooled.
