INSULATING WIRE WITH HIGH THERMAL RESISTANCE AND RESISTANT TO PARTIAL DISCHARGES AND WIRE DRAWING PROCESS

A manufacturing of wires with optimized insulation properties, providing an insulating wire and the wire drawing process for producing it. The wire enamel has three layers: base layer (2), middle layer (3) and top layer (4), wherein these layers wrap around the conducting wire (1) in this order. The wire drawing process is carried out by a) Primary drawing; b) Final drawing and c) Enameling process carried out in line, wherein the enameling is conducted preferably with a specific number of dies for each layer. The process and composition conditions of the wire allowed to provide a triple layer wire that presents high resistance to partial discharges, high thermal class and high resistance to abrasion, thus, increasing the service lifetime of the wire in demanding motor applications when high thermal, high mechanical and high electrical resistance are required.
