Abstract

A cable includes a conductive core, an insulating layer, a shielding layer, and a sheath. The sheath coats the shielding layer. The shielding layer coats the insulating layer. The insulating layer coats the conductive wire. The conductive core includes a conductive wire and a carbon nanotube film comprising a plurality of carbon nanotubes. The carbon nanotubes coat the conductive core.

Claims
