MULTILAYER INSULATED WIRE WHICH COMPRISES INSULATION COATING LAYER AND OUTER COATING LAYER AND HAS HIGH INSULATION PROPERTY AND HEAT RESISTANCE

摘要

PURPOSE: Provided is a multilayer insulated wire, which has excellent heat resistance and insulation property due to reduced heat generation per unit area, and is formed to have a relatively small thickness to be useful for internal circuits of compact electronic products. 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 polyethylene terephthalate(PET) and PET alloy resin; and an outer coating layer(40) formed on the second insulation coating layer(30) through the extrusion of any one selected from the group consisting of polyamide, polyamide-imide and polyethylene terafluoroethylene.
