Abstract
L’invention a pour objet un câble (50) multi-torons à deux couches de multi-torons, le câble (50) comprenant :- une couche interne (CI) du câble constituée de X=3 ou 4 multi-torons M1 de diamètre DM1 comprenant K=2, 3 ou 4 torons (T1) enroulés en hélice autour d’un axe (B), chaque toron (T1) étant à au moins deux couches (C1, C3); - une couche externe (CE) du câble constituée de Y>1 multi-torons M2 de diamètre DM2 enroulés autour de la couche interne (CI) du câble, chaque multi-torons M2 comprenant L=2, 3 ou 4 torons (T2) enroulés en hélice autour d’un axe (A’), chaque toron (T2) étant à au moins deux couches (C1’; C3’) avec les multi-torons de la couche interne (M1) et de la couche externe (M2) étant enroulés en hélice autour d’un axe principal (A).Le câble (50) présente un allongement structural As tel que As ≥ 1,0% et avec un rapport de saturation π x (2 x ReM1 + DM1+DM2)/( Y x DM2) supérieur ou égal à 1,11. Figure pour l’abrégé : Fig 4The invention relates to a multi-strand cable (50) with two layers of multi-strands, the cable (50) comprising: - an internal layer (CI) of the cable consisting of X=3 or 4 multi-strands M1 of diameter DM1 comprising K=2, 3 or 4 strands (T1) wound in a helix around an axis (B), each strand (T1) having at least two layers (C1, C3); - an outer layer (CE) of the cable consisting of Y>1 multi-strands M2 of diameter DM2 wound around the inner layer (CI) of the cable, each multi-strand M2 comprising L=2, 3 or 4 strands (T2) wound helically around an axis (A'), each strand (T2) being at least two-layered (C1'; C3') with the multi-strands of the inner layer (M1) and the outer layer (M2) being wound helically around a main axis (A). The cable (50) has a structural elongation As such that As ≥ 1.0% and with a saturation ratio π x (2 x ReM1 + DM1+DM2)/(Y x DM2) greater than or equal to 1.11. Figure for abstract: Fig 4
