Title (EN) PROCESS FOR MANUFACTURING STRANDED CONDUCTOR COMPRISING INSULATED CONDUCTOR STRANDS
(FR) PROCEDE DE FABRICATION DE CABLES CONDUCTEURS TORONNES COMPRENANT DES TORONS CONDUCTEURS ISOLES
Abstract: front page image
(EN)A process for forming an insulating coating on the surface of each conductor strand in a stranded conductor (30) while maintaining the form of the stranded conductor, said coating comprising an oxide of the metal of the conductor strands. In the step of oxidation treatment of a stranded electric cable conductor, pressure of an oxidation-treating solution (48) into which stranded conductor (30) is dipped is controlled so that the pressure outside the stranded conductor is higher than that inside the stranded conductor (30) to thereby sufficiently force penetration of the oxidation-treating solution (48) into the interior of the stranded conductor (30) to form the desired oxide film on the surfaces of all strands constituting the stranded conductor (30). In order to further facilitate complete penetration of the treating solution (48) into the interior of the stranded conductor (30) or further to accelerate the oxidation reaction, the stranded conductor (30) may be vibrated or slightly untwisted in the oxidation treatment step (40), or may be heated before being introduced into the step (40).
(FR)Procede de formage d"un revetement isolant sur la surface de chaque toron conducteur dans un conducteur toronne (30) tout en maintenant la forme du conducteur, ce revetement comprenant un oxyde du metal composant les torons conducteurs. Pendant l"etape de traitement d"oxydation d"un cable electrique conducteur toronne, la pression d"une solution (48) de traitement par oxydation dans laquelle le conducteur toronne (30) est plonge est controlee de maniere telle que la pression a l"exterieur du conducteur toronne soit superieure a la pression a l"interieur du conducteur toronne (30) de maniere a forcer une penetration suffisante de la solution (48) de traitement par oxydation a l"interieur du conducteur toronne (30) pour former la pellicule d"oxyde desiree sur les surfaces de tous les torons constituant le conducteur toronne (30). Pour faciliter ulterieurement la penetration complete de la solution de traitement (48) a l"interieur du conducteur toronne (30) ou pour acceler ulterieurement la reaction d"oxydation, le conducteur toronne (30) peut etre soumis a une vibration ou legerement detordu pendant l"etape (40) de traitement par oxydation, ou peut etre chauffe avant le commencement de l"etape (40).
