Abstract

1. Cable eléctrico perfeccionado que contando con camisa protectora de al menos una capa, y con una envoltura de cierre situada dentro del cable, que rodea al alma del cable impregnada con masa de junta, caracterizado porque la envoltura de cierre, de forma tubular, está constituida por una cinta de al menos dos capas, que consiste en una hoja portante hidrófoba de plástico, y en una capa hidrófoba de fibrillas sobre al menos una de las caras de la hoja portante, limitando la cara interior de la envoltura tubular de cierre directamente con el alma del cable impregnada con masa de junta en forma que ciñe estrechamente a ella, mientras que su cara exterior limita directamente con la cara interior de la camisa protectora, de al menos una capa. 2. Cable eléctrico perfeccionado, según reivindicación 1, caracterizado porque la cinta que constituye la envoltura tubular de cierre está arrollada helicoidalmente en torno al alma del cable, a la que se ciñe estrechamente y en la que las espiras contiguas de dicha envoltura se solapan parcialmente; siendo susceptible de formar dicha cinta un tubo ranurado longitudinalmente que se ciñe igualmente al alma del cable, quedando los bordes longitudinales de dicho tubo ranurado solapados parcialmente. 3. Cable eléctrico perfeccionado, de acuerdo con las reivindicaciones 1 y 2, caracterizado porque la cara interior de la envoltura tubular de cierre, formada por hoja, se ciñe directa y estrechamente al alma del cable, contenedora de masas de junta, y porque la cara exterior de la envoltura de cierre, formada por la capa de fribrillas, limita directamente con la cara interior de la camisa protectora del cable, constituida por al menos una capa. 4. Cable eléctrico perfeccionado, de acuerdo con las reivindicaciones 1 a 3, caracterizado porque la capa de fibrillas de la envoltura de cierre en el cable consiste en fibrillas de polipropileno de polietileno, o bien en una mezcla de fibrillas de polipropileno y polietileno. 5. Cable eléctrico perfeccionado, de acuerdo con las reivindicaciones 1 a 4, caracterizado porque la hoja portadora de la envoltura de cierre del cable consiste en hoja de poliéster u hoja de polipropileno, orientadas mediante estiraje. 6. Cable eléctrico perfeccionado.
