MULTILAYER INSULATED WIRE AND TRANSFORMER USING SAME

摘要

A multilayer insulated electric wire comprising: a conductor; at least three extruded insulating layers covering the conductor; wherein an outermost layer (A) of the insulating layers is composed of an extruded coating layer containing a polyamide resin and the film thickness is 25 µm or less, wherein an inner layer (B) of the extruded insulating layers is composed of an extruded coating layer containing a crystalline resin having a melting point of 225°C or more or an amorphous resin having a glass transition temperature of 200°C or more.
