摘要
The invention relates to a multi-strand cable (50) comprising an inner layer (CI) of the cable consisting of K = 1 inner strand (TI) with two layers (C1, C3) with the inner layer (C1) consisting of Q wires inner metal (F1) and the outer layer (C3) consisting of N outer metal wires (F3) and an outer layer (CE) of the cable consisting of L> 1 outer strands (TE) with two layers (C1 ', C3') wound around the internal layer (CI) of the cable with the internal layer (C1 ') made up of Q' internal metal wires (F1 ') and the external layer (C3') made up of N 'external metal wires (F3'). The cable (50) has a surface breaking energy ES ≥ 145 N.mm-1 with ES = x x Cfrag / D, with sum of the breaking forces for Nc wires, sum of the total elongation of the Nc wires, Cfrag cable embrittlement coefficient (50) and D cable diameter (50).
