Abstract

Câble dans lequel on a réduit les effets nuisibles des contraintes électriques irrégulières ou disproportionnées aux interfaces entre les couches d'isolant. Il comprend un conducteur électrique métallique de forme allongée 12, enfermé dans une masse composite d'isolant qui l'entoure et qui comprend au moins deux couches contiguës distinctes d'isolant polymère ayant des permittivités différentes placées autour du conducteur électrique de façon à ce que la couche 16 située le plus à l'intérieur de la masse composite d'isolant ait la permittivité la plus élevée et que les couches extérieures successives 18 de la masse composite d'isolant aient des permittivités décroissant graduellement, la permittivité de la couche située le plus à l'intérieur et celle de la couche contiguë qui lui est adjacente dans la masse composite d'isolant étant dans un rapport inférieur à 1,4. Application aux câbles haute tension.
