Patent

CA 2430426

The present invention relates to a process for producing a cable, in particular for medium-tension or high-tension power transmission or distribution. More particularly, the present invention relates to a process for producing a cable, preferably for medium-tension or high-tension power transmission or distribution, which has at least one coating layer made of a thermoplastic polymer material. Said process comprises at least the following steps: (a) extruding a thermoplastic material comprising at least one thermoplastic polymer and at least one dielectric liquid; (b) passing said thermoplastic material through at least one static mixer; (c) depositing and shaping the thermoplastic material around a conductor belonging to the cable so as to obtain a layer of thermoplastic coating on said conductor.

L'invention concerne un procédé de production d'un câble, destiné notamment à la transmission ou à la distribution de puissance moyenne tension ou haute tension. Elle concerne plus particulièrement un procédé de production d'un câble, destiné de préférence à la transmission ou à la distribution de puissance moyenne tension ou haute tension, qui comporte au moins une couche de revêtement faite d'une matière polymère thermoplastique. Le procédé comporte au moins les étapes consistant à : (a) extruder une matière thermoplastique contenant au moins un polymère thermoplastique et au moins un liquide diélectrique ; (b) faire passer cette matière thermoplastique à travers au moins un mélangeur statique ; (c) déposer et façonner la matière thermoplastique autour d'un conducteur faisant partie du câble de manière à former une couche de revêtement thermoplastique sur ce conducteur.
