Abrégé
(EN)
The extracted cable (60') has a 1xN structure comprising a single layer (61) of N strands (62) wound in a helix. Each strand (62) has two layers of metal wires (F1, F2) with diameters D1 and D2. The extracted cable (60') has a structural elongation As' ≥1.00 % and a modulus of elasticity MC' ≤ 80 GPa. The mechanical resistance of at least 50% of the metal wires (F1, F2) with diameters D1 and D2, measured in accordance with standard ASTM D2969-04, is greater than or equal to 3,500-2,000 x D1 for a metal wire with diameter D1 and greater than or equal to 3,500-2,000 x D2 for a metal wire with diameter D2.

Le câble extrait (60') présente une structure 1xN comprenant une unique couche (61) de N torons (62) enroulés en hélice. Chaque toron (62) est à deux couches de fils métalliques (F1, F2) de diamètres D1 et D2. Le câble extrait (60') présente un allongement structural As' ≥1,00 % et un module élastique MC' ≤ 80 GPa. La résistance mécanique d'au moins 50% des fils métalliques (F1, F2) de diamètre D1 et D2, mesurée selon la norme ASTM D2969-04, est supérieure ou égale à 3500-2000 x D1 pour un fil métallique de diamètre D1 et supérieure ou égale à 3500-2000 x D2 pour un fil métallique de diamètre D2.
