"Process to produce a cable provided with at least a thermoplastic coating, and method for enhancing electrical properties, in particular the dielectric strength.Of a thermoplastic material. The present invention relates to a process for producing a cable, in particular for transmission or distribution of energy of medium voltage or high voltage.More particularly, the present invention relates to a process for producing a cable, preferably for the transmission or distribution of energy of medium voltage or high voltage.At least has a coating layer made of a material of thermoplastic polymer.The said process comprises at least the following steps: (a) extrusar a thermoplastic material which comprises at least one thermoplastic polymer and at least one dielectric liquid; (b) to pass theSaid 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.A thermoplastic coating on said conductor.
