Abstract

La présente invention concerne une ligne électrique blindée monofilaire (1) à structure coaxiale comprenant un conducteur électrique (3) entouré de manière concentrique par une couche d'isolation électrique (4), un blindage électrique (5) disposé à la périphérie de la couche d'isolation électrique (4) et une couche d'enveloppe électriquement isolante (7) entourant le blindage électrique (5). La couche d'isolation électrique (4) comporte au moins deux sous-couches concentriques, à savoir au moins une couche radialement intérieure (4a) et au moins une couche radialement externe (4b). L'épaisseur de paroi (Sa) de la couche extérieure (4b) est dimensionnée en fonction de la tolérance de concentricité de la structure de la ligne (1) de telle sorte qu'elle est supérieure/égale à la profondeur de pénétration d'un outil de coupe dans la couche intérieure (4a) lors de l'enlèvement de la couche d'enveloppe (7) et du blindage (5). La couche intérieure (4a) a au moins une épaisseur de paroi (Si) qui est conçue pour une résistance électrique de claquage à une tension électrique de service donnée, et la densité de matière de la couche extérieure (4b) est supérieure à la densité de matière de la couche intérieure (4a).
