Abstract
L’invention concerne un câble (50) multi-torons comprenant une couche interne (CI) du câble constituée de K=3 ou 4 torons internes (TI) à deux couches (C1, C3) avec la couche interne (C1) constituée de Q fils métalliques internes (F1) et la couche externe (C3) constituée de N fils métalliques externes (F3) et une couche externe (CE) du câble constituée de L>1 torons externes (TE) à deux couches (C1’, C3’) enroulés autour de la couche interne (CI) du câble avec la couche interne (C1’) constituée de Q’ fils métalliques internes (F1’) et la couche externe (C3’) constituée de N’ fils métalliques externes (F3’). Le câble (50) présente une énergie à rupture surfacique ES ≥ 160 N.mm-1 avec ES= x x Cfrag / D, avec somme des forces à rupture pour Nc fils, somme de l’allongement total des Nc fils, Cfrag coefficient de fragilisation du câble (50) et D diamètre du câble (50).
