▎ 摘　　要

NOVELTY - The electrical conductor comprises an electrically conducting fiber (1) comprising carbon nanotubes and/or graphene nanoribbon, and a layer of an insulating material (5) coated around the electrically conducting fiber. The insulating material does not penetrate the electrically conducting fiber or penetrates the electrically conducting fiber only to a depth that leaves a continuous conductive path along a remaining part of the electrically conducting fiber. The electrically conducting fiber comprises 75 wt.% of carbon nanotubes. USE - The electrical conductor is useful in an electrical or electronic device (claimed), a power transmission cable, a lightning protection system, current-carrying windings of an electromagnet such as solenoid, electric motor and electric generator, and data transmission wiring. ADVANTAGE - The infiltration of the fiber by the insulating material can cause significant reduction in conductivity when applying insulating coatings to conducting fibers comprising carbon nanostructures such as carbon nanotubes thus achieving very high electrical performance at room temperature. DETAILED DESCRIPTION - The electrical conductor comprises an electrically conducting fiber (1) comprising carbon nanotubes and/or graphene nanoribbon, and a layer of an insulating material (5) coated around the electrically conducting fiber. The insulating material does not penetrate the electrically conducting fiber or penetrates the electrically conducting fiber only to a depth that leaves a continuous conductive path along a remaining part of the electrically conducting fiber. The electrically conducting fiber comprises 75 wt.% of carbon nanotubes. The insulating material does not penetrate the electrically conducting fiber or penetrates the electrically conducting fiber only to a depth of not more than 10% of the radius of the fiber. The electrically conducting fiber has a diameter of less than 1 mm. The insulating material does not penetrate the electrically conducting fiber or penetrates the electrically conducting fiber only to a depth of not more than 5 mu m from the surface of the fiber. The electrical conductor has a conductivity of 0.7x 106 Sm-1.
