Grapheme-nanomaterial-based conductive wire

Abstract

The invention provides a grapheme-nanomaterial-based conductive wire, belongs to the technical field of conductive wires for overhead transmission lines, and solves the problems that improvement on the conductivity of aluminum and copper and other conventional metal materials is limited and the transmission capacity of an overhead transmission line is limited. The grapheme-nanomaterial-based conductive wire comprises two structures as follows: 1, the grapheme-nanomaterial-based conductive wire comprises an inner layer and an outer layer, wherein the inner layer is formed by twisting monofilaments of steel or carbon fiber, nanotube monofilaments of a grapheme nanomaterial or composite monofilaments, and the outer layer is formed by twisting arc grapheme nanomaterial sheets; 2, the grapheme-nanomaterial-based conductive wire is formed by twisting circular linear nanotube monofilaments of the grapheme nanomaterial or the composite monofilaments, wherein the monofilament are tightly adhered to one another to form a regular tubular structure, circular cross sections of the composite monofilaments are made of a carbon fiber composite material, and the grapheme nanomaterial is filled into the circular cross sections. The grapheme-nanomaterial-based conductive wire can effectively reduce the line loss and improve the transmission power of the overhead transmission line, and has an allowable current-carrying capacity which is 10 times as that of an ordinary wire under the same external conditions.

Description

technical field [0001] The invention belongs to the technical field of wires for overhead transmission lines, and in particular relates to a wire based on graphene nanomaterials. Background technique [0002] The loss of transmission lines mainly depends on the resistance of the wires. The application of high-conductivity wires can not only significantly reduce the loss of transmission lines, but also increase transmission capacity, reduce life cycle costs, and achieve energy saving and emission reduction. [0003] In recent years, the high-conductivity wires developed successively in China mainly improve the conductivity of the wires from the aspect of metal material composition. These wires still use traditional metal materials, and the improvement of conductivity is limited. [0004] For example, the application number is CN200810194862.7, the invention name is an invention patent of a high-conductivity annealed aluminum wire and its manufacturing method, which discloses ...
