MULTILAYER INSULATED WIRE WHICH COMPRISES INSULATION COATING LAYER AND OUTER COATING LAYER AND HAS EXCELLENT INSULATION PROPERTY, HEAT STABILITY, WEAR RESISTANCE AND HEAT RESISTANCE

摘要

PURPOSE: Provided is a multilayer insulated wire, which has a relatively small thickness to be used in internal circuits of compact electronic products, thereby giving excellent heat stability and insulation property due to reduced heat generation per unit area, as well as showing excellent heat resistance and wear resistance. CONSTITUTION: The multilayer insulated wire comprises: a conductive body(10) formed of copper or alloy wire; a first insulation coating layer(20) and a second insulation coating layer(30) formed on the conductive body(10) through the extrusion of a resin blend of polyethylene terephthalate with polyethylenenaphthalene dicarboxylate in two or more layers; and an outer coating layer(40) formed on the second insulation coating layer(30) through the extrusion of polyamide resin.
