▎ 摘　　要

NOVELTY - The wire has an inner layer and an outer layer, where the inner layer is formed by twisting monofilaments of steel or carbon fiber and the nanotube monofilaments or composite monofilaments of a circular wire type graphene nanomaterial. The outer layer is formed by twisting graphene nanomaterial sheets. The monofilaments are attached to each other tightly to form a regular tubular structure. A circular cross-section of each monofilaments is provided with a carbon fiber composite material. USE - Conducting wire for an overhead power transmission line. ADVANTAGE - The wire can effectively reduce line loss and improve transmission power of the overhead power transmission line and allowable current-carrying capacity compare to an ordinary conducting wire under the same external conditions. DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of a conducting wire.
