05.2 Strand construction of wire ropes pt. 2
The make of a strand is the law of formation according to which the wires are arranged relative to each other. For example, all strands of the Seale type have the structure 1 – n – n (with n = 3, 4, 5, 6, 7, 8, 9 …). Wire layers which are stranded together in parallel in the same operation are connected by a minus sign ” – ” in the designation according to EN 12385-3. The designation of a Seale 17 strand is thus 1 – 8 – 8, the designation of a Seale 19 strand is 1 – 9 – 9.
