Abstract

Mejoras en la construcción de cables eléctricos, caracterizadas por un proceso para pantallear eléctricamente cables con aluminio, o con una aleación compuesta, principalmente de aluminio, la cual consiste en inyectar un tubo del metal alrededor del alma del cable aislado, siendo dicho tubo de un diámetro interior tal que el tubo quede separado del cable, estando protegido dicho cable de los peligros, debidos a la alta temperatura en la prensa de inyección durante la operación de inyección, y además, estirado el tubo inyectado al diámetro requerido para formar una cubierta apretada sobre el alma del cable, la operación de estirado se hace cuando la estructura del tubo se ha enfriado suficientemente.Improvements in the construction of electrical cables, characterized by a process to electrically shield cables with aluminum, or with a composite alloy, mainly aluminum, which consists of injecting a metal tube around the core of the insulated cable, said tube being a internal diameter such that the tube is separated from the cable, said cable being protected from the dangers, due to the high temperature in the injection press during the injection operation, and furthermore, the injected tube is stretched to the required diameter to form a tight cover On the core of the cable, the stretching operation is done when the structure of the tube has cooled sufficiently.
