Abstract

Un cable eléctrico, en particular para transmision o distribucion de energía de media o alta tension, que tiene una pantalla metálica y una capaexpandida semiconductora que bloquea el agua. Esta capa tiene tres funciones principales: la primera esab sorber elástica y uniformemente fuerzas radialesde expansion y contraccion de las capas de recubrimiento del cable debido a ciclos térmicos del cable durante el uso, evitando así deformaciones o roturasen la pantalla metálica; la segunda esasegurar continuidad eléctrica entre el nucleo del cable y la pantalla metálica; la tercera es evitarefectivamente la penetracion y propagacion de humedad y/o agua a lo largo del nucleo del cable debido, por ejemplo a posibles roturas en laspantallametálica. La tercera funcion se obtiene incluyendo en la capa expandida un material que se expande en el agua.An electric cable, in particular for transmission or distribution of medium or high voltage energy, which has a metal screen and an expanded semiconductor layer that blocks the water. This layer has three main functions: the first one to sip elasticly and uniformly radial forces of expansion and contraction of the layers of cable covering due to thermal cycles of the cable during use, thus avoiding deformation or breakage in the metal screen; the second is to ensure electrical continuity between the cable core and the metal screen; the third is to prevent the penetration and propagation of moisture and / or water along the cable core due to, for example, possible breaks in the metal screen. The third function is obtained by including in the expanded layer a material that expands in the water.
