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.
