Abstract

Perfeccionamientos en aislamientos de cables de transmisión de energía eléctrica de alto voltaje, caracterizados porque se dota a cada cable transmisor de un conductor, un blindaje del conductor, aislamiento, blindaje del aislamiento y blindaje exterior, y un compuesto de relleno adherido a uno de los blindajes para evitar la emigración de agua en el sentido longitudinal a lo largo del blindaje, siendo el material de relleno polipropileno amorfo.
