TWO-LAYER MULTI-STRAND CABLE HAVING IMPROVED FRACTURE SURFACE ENERGY

The invention relates to a multi-strand cable (50) comprising a cable core (Cl) consisting of K=1 inner strand (Tl) that has two plies (C1, C3), wherein the inner ply (C1) consists of Q inner metal wires (F1) and the outer ply (C3) consists of N outer metal wires (F3), and an outer layer (CE) of the...

Beschreibung
Zusammenfassung:	The invention relates to a multi-strand cable (50) comprising a cable core (Cl) consisting of K=1 inner strand (Tl) that has two plies (C1, C3), wherein the inner ply (C1) consists of Q inner metal wires (F1) and the outer ply (C3) consists 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 cable core (Cl), wherein the inner ply (C1') consists of Q' inner metal wires (F1'), the intermediate ply (C2') consists of M' intermediate metal wires (F2') and the outer ply (C3') consists of N' outer metal wires (F3'). The cable (50) has a fracture surface energy ES > 155 N.mm-1, where ES = (a), where (b) is the sum of the forces at break for Ne wires, (c) is the sum of the total elongation of the Nc wires, Cfrag is the embrittlement coefficient of the cable (50), and D is the diameter of the cable (50).
