Abstract

La présente invention concerne un câble à tube de blindage métallique résistant à la traction qui est un type de fil isolé, de câble commun ou de fibre enveloppé par un tube métallique élastique résistant à la traction. Le câble ou fil isolé en rouleau est mis dans un châssis principal de moulage de blindage du câble blindé par tube métallique résistant à la traction, et moulé par le tube résistant à la traction élastique en métal une fois, et connecté enfin par la section de bobinage, de cette façon le câble est produit. La vitesse et le sens de rotation de l'étrier à fil, de l'étrier à câble, et du câble blindé du tube résistant à la traction en métal moulé dans l'axe du noyau du châssis principal de moulage de blindage sont les mêmes. Le châssis principal de moulage de blindage pour la production est amélioré depuis la machine à tube de blindage résistant à la traction élastique en métal, lequel axe de noyau est vide au lieu d'être solide, et le diamètre mineur n'est pas inférieur au diamètre du câble se déblindant.
