Summary:The invention relates to a multi-strand cable (50) comprising an inner layer (Cl) of the cable, 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 an outer layer (CE) of the cable, consisting of L>1 outer strands (TE) that have three plies (C1', C2', C3') and are wound around the inner layer (Cl) of the cable, the inner ply (C1') consisting of Q' inner metal wires (F1'), the intermediate ply (C2') consisting of M' intermediate metal wires (F2') and the outer ply (C3') consisting of N' outer metal wires (F3'). The cable (50) has: - an endurance criterion SL ≤ 40000 MPa.mm where SL = max (F); and - an overall dimension criterion Ec ≥ 0.46 where E = Sc/Se.
