Improved method for manufacturing a medium- or high-voltage electric cable

Abstract

The invention relates to a method for manufacturing a medium- or high-voltage electric cable, of the type comprising: a core formed of an elongate electrically conductive element and of an insulating system comprising at least one layer comprising at least one cross-linked polyethylene, said at least one layer being arranged coaxially around the elongate electrically conductive element, and a tape enveloping the core the tape being formed of a semiconductor polymer material., characterised in that the method comprises at least one step of extracting at least one chemical species from the tape, said chemical species being a chemical species able to reach the insulating system by migration from the tape and to decrease the dielectric performance of the insulating system.
