In addition to effectively preventing elongation, that is, cutting, of the signal line or electric wire 2, excellent reinforcement performance is exhibited, and each side strand 12 is configured to have a moderately small diameter D 2 with respect to the core strand 11, and A suitable gap α is formed between the strands in a configuration in which the strands 12 are appropriately molded and twisted to the core strands 11, so that friction between the core strands and the side strands and between the side strands is effectively reduced. , Wire rope 1
The curve deformation performance of No. 0 is remarkably enhanced. Also, at least the diameter ratio r of the core strand 11 and the side strand 12
= D1 / D2 in the range of 1.08 to 1.10, or alternatively, the preform degree of the side strand η = h / RD is 80

Deformed rope reinforced composites (communication cables and belt cables)
Embedded in the direction of curvature deformation
In the reinforcing wire rope, a plurality of side strands formed in a small diameter with respect to the core strand are molded, and the side strands are twisted to the core strand to form a gap between the strands, thereby forming a highly flexible wire rope. When the diameter of the core strand is D1 and the diameter of each side strand is D2, the diameter ratio of the core strand to the side strand is D1. r = D1 / D2 is 1.08 to 1.10
Alternatively, assuming that the preform height of the side strand is h and the diameter of the wire rope is RD, the preform degree η = h / RD of the side strand is 80.
To 85, a moderately low rope elongation is secured by increasing the diameter of the core strand relative to the side strand, and a highly flexible structure is formed by forming a gap. In addition, the bending deformation performance as well as the reinforcement performance and reliability are remarkably improved, for example, damage due to the twisting phenomenon is prevented.
