Abstract

Se trata de un cable eléctrico, en particular para la transmisión o para la distribución de energía de medio o de alto voltaje, que comprende una protección metálica y una capa hidro-expansible capaz de formar una barrera contra la penetración del agua provista en una posición radialmente externa respecto a dicha protección metálica. Dicha capa hidro-expansible está hecha de un material polimérico expandido donde se incorpora un material hidro-expansible, preferentemente en forma de polvo.
