Abstract

"PROCESSO PARA PRODUZIR UM CABO FORNECIDO COM PELO MENOS UM REVESTIMENTO TERMOPLáSTICO, E, MéTODO PARA REALçAR AS PROPRIEDADES ELéTRICAS, EM PARTICULAR A RIGIDEZ DIELéTRICA, DE UM MATERIAL TERMOPLáSTICO". A presente invenção diz respeito a um processo para produzir um cabo, em particular para transmissão ou distribuição de energia de média tensão ou alta tensão. Mais particularmente, a presente invenção diz respeito a um processo para produzir um cabo, preferivelmente para transmissão ou distribuição de energia de média tensão ou alta tensão, que tem pelo menos uma camada de revestimento fabricada de um material de polímero termoplástico. O dito processo compreende pelo menos as seguintes etapas: (a) extrusar um material termoplástico que compreende pelo menos um polímero termoplástico e pelo menos um líquido dielétrico; (b) passar o dito material termoplástico através de pelo menos um misturador estático; (c) depositar e dar forma ao material termoplástico em torno de um condutor pertencente ao cabo de modo a obter uma camada de revestimento termoplástico no dito condutor.
