Alambre aislante con alta resistencia térmica y resistencia a descargas parciales y proceso de trefilado de alambre

The invention is related to the manufacturing of wires with optimized insulation properties, providing an insulating wire and the wire drawing process for produdng this insulating wire. The wire enamel comprises 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 comprises the step of 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.
