Claim:
Strand cable comprising three strands twisted together in helix with pitch p 2 , each consisting of two metallic wires twisted together in helix with pitch p 1 , the wires of each strand and the strands being twisted together in the same twist direction S/S or Z/Z and the two wires of each of the three strands having diameters (d 1 , d 2 ), (d 1 ′, d 2 ′), (d 1 ″, d 2 ″), respectively, such that the cable as a whole satisfies the following conditions: (i) 0.25 < d1 < 0.45 (ii) 0.25 < d2 < 0.45 (iii) 0.25 < d1′ < 0.45 (iv) 0.25 < d2′ < 0.45 (v) 0.25 < d1″ < 0.45 (vi) 0.25 < d2″ < 0.45 (vii) 2 < p1 < p2 < 10.
