Preparation of an electrical cable by continuous extrusion of a thermoplastic insulating layer and an outer thermoplastic sheath

Abstract

The present invention relates to a continuous manufacturing process for an electrical cable (1) comprising an elongated electrically conductive element (2), an insulating layer (3) surrounding said elongated electrically conductive element, and a sheath (4) surrounding said insulating layer, wherein: - the insulating layer (3) is extruded around said elongated electrically conductive element (2) from a first non-crosslinkable thermoplastic polymer composition C1; and - the sheath (4) is extruded around the insulating layer (3) from a second non-crosslinkable thermoplastic polymer composition C2, distinct from composition C1.
