Abstract: An electrical cable includes at least one conductor and a barrier arranged externally to the at least one conductor. The barrier includes two first layers including an inorganic material and a second layer including a polymer-metal composite material, the second layer being interposed between the two first layers. The electrical cable also includes, in an intermediate position between the at least one conductor and the barrier, solely discontinuous layers and/or layers of non-thermally-collapsible materials.

Abstract: A cable for applications which entails heavy mechanical stresses and/or harsh environmental conditions includes at least one core having at least one transmissive element and an outer sheath disposed in radially external position with respect to the core. The outer sheath includes a reinforcing layer including a fibril reinforced polymeric matrix. A process for manufacturing such a cable includes the steps of providing a core having at least a transmissive element; providing a first compound of fibrils and a matrix; and applying the first compound around the core to form the reinforcing layer including the fibril reinforced polymeric matrix. The invention also deals with the use of fibrils for the manufacturing of a coating layer for a cable.
