Abstract
FABRICACION DE CABLES ELECTRICOS PARA TENSIONES MEDIAS. COMPRENDEN UNA O VARIAS ANIMAS, CADA UNA DE LAS CUALES ESTA CONSTITUIDA POR UN CONDUCTOR RECUBIERTO POR UNA PANTALLA SEMICONDUCTORA INTERIOR, UN AISLANTE DE BASE POLIMERA, EXTRUIDO Y VULCANIZADO, Y UNA PANTALLA SEMICONDUCTORA EXTERIOR, EXTRUIDA SOBRE EL AISLANE Y VULCANIZADA SIMULTANEAMENTE CON EL MISMO. SE FORMA LA PANTALLA SEMICONDUCTORA EXTERIOR POR EXTRUSION SOBRE EL CONDUCTOR, PREVIAMENTE PROVISTO DE LA PANTALLA SEMICONDUCTORA INTERIOR Y DEL AISLANTE DE UNA COMBINACION DE GOMA NITRILO Y DE GOMA DE ETILENO-PROPILENO, COMPRENDIENDO ESTA MEZCLA NEGRO DE HUMO Y AGENTES RETICULANTES, SEGUIDA DE VULCANIZACION SIMULTANEA DE LOS REFERIDOS PANTALLA SEMICONDUCTORA EXTERIOR AISLANTE. LA GOMA DE NITRILO ES UN COPOLIMERO BUTADIENO-ACRILONITRILO CON UN 35 PP DE ACRILONITRILO, SIENDO LA MEZCLA DE LA PANTALLA SEMICONDUCTORA POLIETILENO CLORURADO. R
