Abstract
Un câble électrique et un procédé de fabrication de ce câble électrique dans lequel une pluralité de conducteurs isolés comporte une couche de protection interne extrudée tout autour. Une pluralité de côtes ou de nervures ou de surfaces extérieures côtelées ou nervurées s'étendant longitudinalement est formée à l'extérieur de la couche de protection interne entre lesquelles se trouve une pluralité de vides. Une couche isolante externe peut être formée en même temps que les nervures ou la surface côtelée et la couche interne lors d'une opération subséquente.
