Abstract: An electrical device for detecting moisture has a detection cable (10a, 10b, 10c) made up of a first element (1) and of a second element (2a, 2b, 2c) which elements are elongate and electrically conducting and separated by a polymer-based material (3), and an electrical resistance measurement appliance intended to measure the electrical resistance between the first and second elements of the the cable, where the material (3) is a non-soluble and moisture-sensitive material.

Abstract: The present invention relates to an electrical control cable of the type comprising a core having a plurality of polymer filaments, a plurality of strands of conductor material extending in the longitudinal direction of said core, an outer insulating sheath. According to the invention, said strands are distributed uniformly and concentrically over the periphery of said core, in contact with one another in pairs and in contact with said core, and the filaments of said core are secured to one another to form a non-metallic unitary structure that is obtained by organizing said filaments into a plurality of subassemblies, the filaments in any one subassembly being twisted together helically, the subassemblies in turn being twisted with one another to form an overall helix. Advantage: the cable uses a limited number of copper strands while guaranteeing that crimping operations are reliable.

Abstract: The invention relates to an electrical conductor coated in an insulating layer itself coated in a bonding layer, the conductor being characterized in that said bonding layer is obtained from a composition comprising a thermoplastics polymer and a settable resin. The invention also applies to a method of manufacturing such an electrical conductor coated in a bonding layer, the method being characterized in that it comprises applying said composition on said electrical conductor coated in said insulating layer, and applying treatment to cause said settable resin to be cured at least in part.

Abstract: A method of preparation for a layer of material for use with a power and/or telecommunications cable includes mixing a composition including a thermoplastic polymer matrix and a phenolic resin. The phenolic resin is selected from the group consisting of novolac phenol-formaldehyde resins and novolac cyanate ester resins. The phenolic resin is hardened within the thermoplastic polymer matrix to obtain nodules of hardened phenolic resin dispersed throughout the material.

Abstract: A composite control cable has a polymer core and a plurality of strands of electrically conductive material extending in the longitudinal direction of the cable around said core. The polymer is selected from polymers presenting elongation at break that is greater than 7%, and traction strength such that the resultant traction strength of the cable is greater than a predetermined limit value.
