Abstract (en)
[origin: WO2021140287A1] The invention relates to a multi-strand cable (50) having a 1xN structure comprising a single layer (52) of N strands (54) that are helically wound about a main axis (A), each strand (54) consisting of a layer (56) of metal wires (F1) and comprising M>1 metal wires that are helically wound about an axis (B). The cable (50) has a total elongation At > 8.10%, and the energy-at-break index Er = rAt of the cable (50) is defined as Er = ∫ AT σ(Αί) x dAi, where σ(Αί) is the tensile stress in MPa measured at the elongation Ai, and dAi is the elongation such that Er is strictly greater than 52 MJ/m3.
