Abstract

Un cable eléctrico bloqueado a gas, balanceado por par de torsión y un método para formar el cable incluye un núcleo de cable eléctricamente conductor para transmitir energía eléctrica y forro circundante y capas externas de una pluralidad de cables acorazados. Se logra el bloqueo por gas colocando una capa de polímero suave sobre el núcleo antes de que los alambres internos sean cableados sobre el mismo. Los alambres internos se embeben parcialmente en la capa de polímero suave de manera que no queden espacios entre los alambres internos y el núcleo. Una segunda capa de polímero suave se extruye opcionalmente sobre los alambres internos antes de que se apliquen los alambres externos. La segunda capa de polímero suave llena cualquier espacio entre las capas de alambres internos y externos y evita que el gas presurizado se infiltre entre los alambres. Los alambres internos tienen diámetros mayores que los alambres externos de manera que los alambres internos llevan aproximadamente el 60 de la carga y se evita el desbalance del par de torsión.
