Abstract (en)
[origin: WO2021099712A1] The invention relates to a multi-strand cable (50) comprising a cable inner layer (Cl) consisting of K=1 inner strand (Tl) that has two plies (C1, C3), the inner ply (C1) consisting of Q inner metal wires (F1) and the outer ply (C3) consisting of N outer metal wires (F3), and a cable outer layer (CE) consisting of L>1 outer strands (TE) that have two plies (CT, C3') and are wound around the inner layer (Cl) of the cable, the inner ply (C1) consisting of Q' inner metal wires (FT) and the outer ply (C3') consisting of N' outer metal wires (F3'). The cable (50) has a surface energy-to-break ES > 145 N.mm-1, with ES = ∑fSt Fmi x ∑fSt Ati/Ncx Cfrag/D, where ∑fSt Fmi is the sum of the forces at rupture for Nc wires, ∑fSt Ati is the sum of the total elongation of the Nc wires, Cfrag is the coefficient of embrittlement of the cable (50), and D is the diameter of the cable (50).
