Abstract

La presente se refiere a un procedimiento para fabricar un cable, comprendiendo dicho cable: un conductor; una capa semiconductora interior que rodea a dicho conductor y que tiene un espesor menor que o igual a 0,4 mm; y una capa aislante que rodea a dicha capa semiconductora interior. El procedimiento comprende el paso de co-extruir la capa semiconductora interior y la capa aislante. Dicho paso comprende: a) proveer un primer flujo anular de material semiconductor interior y un segundo flujo anular de material aislante; b) poner en contacto a la superficie exterior de dicho primer flujo anular y a la superficie interior de dicho segundo flujo anular a una distancia axial del punto de contacto, en donde la superficie interior de dicho primer flujo anular se pone en contacto con el conductor; c) seleccionar en combinacion dicha velocidad de alimentacion predeterminada y dicho punto de contacto d), como una funcion de la viscosidad dinámica (eta) del material semiconductor interior y del material aislante, de modo que una relacion entre el esfuerzo de corte de la capa semiconductora interior en la pared radialmente interior de la matriz de extrusion y el esfuerzo de corte de la capa aislante en la pared radialmente exterior de la matriz de extrusion, cerca de dicho punto de contacto, está comprendida entre aproximadamente 0,5 y 4; d) extruir por compresion la capa aislante y la capa semiconductora interior sobre el conductor.
