Abstract
A transmission line cable with conductors includes a metal-matrix composite (MMC) conductor of carbon nanotubes (CNT) dispersed in aluminum (Al) metal matrix. The concentration of CNT is uniform throughout an entirety of the MMC conductor.
Claims22
A transmission or distribution line cable comprising:
- a plurality of conductors comprising:
- a metal-matrix composite (MMC) conductor comprising:
- a plurality of carbon nanotubes (CNT) that are evenly dispersed in an aluminum (Al) metal matrix,
- wherein the concentration of CNT is uniform throughout an entirety of the MMC conductor.
1 more element
A transmission or distribution line cable comprising:
- a plurality of wires forming a stranded core;
- and
- a plurality of conductors stranded around the stranded core,
- wherein the plurality of conductors comprises a metal-matrix composite (MMC) of aluminum (Al) and carbon nanotubes (CNT) having a non-porous structure with CNT dispersed uniformly throughout the MMC.
1 more element
A method of manufacturing an aluminum carbon nanotube (Al-CNT) composite wire for a transmission or distribution line cable, the method comprising:
- extruding a non-porous rod of Al-CNT with an initial diameter;
- and
- reducing the cross-sectional area of the rod successively by a working process to form a non-porous Al-CNT composite conductor of a final diameter less than the initial diameter.
