Abstract

Un cable de fuerza mejorado a prueba en su aislamiento de los denominados "árboles de agua" el cual comprende un conductor provisto de una o más capas de material de aislamiento polimérico extruido así como una capa semiconductora interior y otra exterior, caracterizado porque fuera e independiente de la capa semiconductora exterior hay dispuesta una capa que contiene materiales solubles en el agua que de modo ya conocido limita y estabiliza la humedad relativa que lo rodea, incluido el aislamiento del conductor, hasta un valor que no sobrepasa el 70%.
