Abstract

A structure of a conducting wire based on a graphene nanomaterial is as follows: form I, the conducting wire comprises an inner layer and an outer layer, the inner layer is formed by twisting the monofilaments of steel or carbon fibre and nanotube monofilaments or composite monofilaments of graphene nanomaterial; and the outer layer is formed by twisting graphene nanomaterial sheets; form II, the conducting wire is formed by twisting nanotube monofilaments or composite monofilaments of circular wire type graphene nanomaterials; the monofilaments are attached to each other tightly to form a regular tubular structure; wherein a circular cross-section of a composite monofilament is a carbon fibre composite material; and the interior of the circular cross-section is graphene nanomaterial. The conducting wire based on graphene nanomaterial can effectively reduce line loss, improve the transmission power of an overhead power transmission line; and the allowable current-carrying capacity of the graphene conducting wire is ten times that of an ordinary conducting wire.

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 ...
