Document Type and Number:
WIPO Patent Application WO/2011/090133
Kind Code:
A1
Abstract:
Provided is a low-sag increased-capacity composite electric cable obtained by twisting wires comprising a composite material which is an aluminum material containing carbon nanotubes dispersed therein and which has high mechanical strength and excellent conductivity. The composite electric cable comprises a plurality of wire materials twisted together, and is characterized in that the wire materials comprise wires which comprise a composite material comprising an aluminum material and carbon nanotubes dispersed in the aluminum material and which have a cell structure comprising a partition part containing carbon nanotubes and a partition interior part surrounded by the partition part and comprising an aluminum material and incidental impurities, the ratio of the amount of the carbon nanotubes to the amount of the aluminum material in the wires being in the range of 0.2-5 wt.%. The composite electric cable is further characterized in that all the wire materials constituting the composite electric cable are the wires or that the composite electric cable has one or more steel wires in the center.
