Abstract:
Stranded composite cables include a single wire defining a center longitudinal axis, a first multiplicity of composite wires helically stranded around the single wire in a first lay direction at a first lay angle defined relative to the center longitudinal axis and having a first lay length, and a second multiplicity of composite wires helically stranded around the first multiplicity of composite wires in the first lay direction at a second lay angle defined relative to the center longitudinal axis and having a second lay length, the relative difference between the first lay angle and the second lay angle being no greater than about 4°. The stranded composite cables may be used as intermediate articles that are later incorporated into final articles, such as overhead electrical power transmission cables including a multiplicity of ductile wires stranded around the composite wires. Methods of making and using the stranded composite cables are also described.
