Abstract

L'invention concerne l'extrusion des matières polymères des câbles à haute tension. Elle se rapporte à un procédé qui comprend l'extrusion, le refroidissement et la réticulation au cours de l'extrusion de matières polymères, lors de la réalisation d'un câble à haute tension dans lequel le conducteur est entouré par une couche interne semi-conductrice, une couche isolante et une couche externe semi-conductrice. Selon l'invention, le refroidissement de la matière est réalisé avant la réticulation. Application à la réalisation de câbles à haute tension.
