Abstract
Procédé et dispositif de fabrication de câbles électriques remplie de poudre. Suivant le procédé de la présente invention, on fait passer les torons 60 du câble espacés les uns des autres dans une chambre fermée 12 et de la poudre est introduite de façon continue dans la chambre, dans le trajet des conducteurs. La partie de la poudre qui retombe au fond de la chambre 20 est remise en circulation et on admet dans la chambre de la poudre supplémentaire lorsque l'on a utilisé la quantité de poudre retombée pour remplir l'âme. Application à la fabrication en continu de cables électriques à plusieurs torons, comportant une seule gaine ou une gaine intérieure et une gaine extérieure, pour remplir, au moins partiellement, de poudre destinée à empêcher l'entrée et la migration de l'eau dans le câble les interstices compris entre les conducteurs du câble ou l'espace compris entre les gaines intérieure et extérieure.Method and device for manufacturing electric cables filled with powder. In accordance with the method of the present invention, the strands 60 of the cable spaced from one another are passed through a closed chamber 12 and powder is continuously introduced into the chamber, in the path of the conductors. The part of the powder which falls to the bottom of the chamber 20 is recirculated and additional powder is admitted into the chamber when the quantity of powder which has fallen back has been used to fill the core. Application to the continuous manufacture of electric cables with several strands, comprising a single sheath or an inner sheath and an outer sheath, to fill, at least partially, with powder intended to prevent the entry and migration of water into the cable the gaps between the conductors of the cable or the space between the inner and outer sheaths.
