▎ 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 graphene nanomaterial. The outer layer is formed by twisting circular arc type graphene nanomaterial sheets. The monofilaments are attached to each other tightly to form a regular tubular structure. A circular cross-section of the composite monofilaments is provided with a carbon fiber composite material. USE - Conducting wire for an overhead power transmission line. ADVANTAGE - The wire improves electric conductivity and transmission capacity of an overhead power transmission line. The wire can effectively reduce line loss and improve transmission power of the overhead power transmission line, 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.
