摘要： A cable for use in a predetermined voltage class includes at least one conductor; at least one extruded insulating layer surrounding the conductor, the insulating layer being made from a non-crosslinked insulating material having at least one thermoplastic polymer and at least one dielectric liquid, the insulating layer having a thickness such as to provide a voltage gradient on the outer surface of the cable insulating layer not smaller than 1.0 kV/mm; and a protective element around the extruded insulating layer having a thickness and mechanical properties selected to provide a predetermined impact resistance capability, the protective element having at least one expanded polymeric layer, the thickness being sufficient to prevent detectable insulating layer damage upon impact of at least 25 J energy. The insulating layer thickness and the protective element thickness can be selected in combination to minimize the overall cable weight while preventing detectable insulating layer damage upon impact of at least 25 J energy.

摘要： A process for manufacturing an electric cable. In particular, the process includes the steps of: a) feeding a conductor at a predetermined feeding speed; b) extruding a thermoplastic insulating layer in a position radially external to the conductor; c) cooling the extruded insulating layer; and d) forming a circumferentially closed metal shield around the extruded insulating layer. The process may be carried out continuously, i.e., the time occurring between the end of the cooling step and the beginning of the shield forming step is inversely proportional to the feeding speed of the conductor.
