Abstract
An electrical transmission line for transmitting electricity is made of a composite material in which aluminum and a plurality of carbon nanotubes are combined, and a weight ratio of the carbon nanotubes to the aluminum is 0.5 to 3 wt %. The carbon nanotubes are oriented at an angle within 30° along a length direction of the electrical transmission line.
Claims6
An electrical transmission line for transmitting electricity,
- wherein the electrical transmission line is made of a composite material in which aluminum and a plurality of carbon nanotubes are combined, and a weight ratio of the carbon nanotubes to the aluminum is 0.5 to 3 wt %,
- wherein 80% or more of the plurality of carbon nanotubes are oriented at an angle within 30° along a length direction of the electrical transmission line.
An electrical transmission line in which a plurality of conductor units playing both roles of transmitting electricity and supporting a wire extend in a twisted pattern,
- wherein the conductor units are made of a composite material in which aluminum and a plurality of carbon nanotubes are combined, and a weight ratio of the carbon nanotubes to the aluminum is 0.5 to 3 wt %,
- wherein 80% or more of the plurality of carbon nanotubes are oriented at an angle within 30° along a length direction of the conductor units.
An electrical transmission line, which includes a central tension wire and a plurality of conductor units extending on an outer periphery of the central tension wire in a twisted pattern,
- wherein at least one of the central tension wire and the conductor units is made of a composite material in which aluminum and a plurality of carbon nanotubes are combined, and a weight ratio of the carbon nanotubes to the aluminum is 0.5 to 3 wt %,
- wherein 80% or more of the plurality of carbon nanotubes are oriented at an angle within 30° along a length direction of the central tension wire or the conductor units.
