Abstract

The invention discloses a conductor having a built-in stranded inner core and capable of reducing AC resistance. The conductor comprises an inner conductor, wherein the inner conductor enables itself to have positive charges after being electrified by positive DC electricity, the inner conductor comprises multiple inner cores and a filling material, the multiple inner cores are stranded into a bundle, an outer surface of the stranded multiple-core bundle is externally wrapped in an inner insulation layer, the filling material is filled between the stranded multiple-core bundle and the inner insulation layer, an outer surface of the inner insulation layer is wrapped in an outer conductor used for transmitting AC electricity, the inner conductor, the inner insulation layer and the outer conductor are coaxially arranged, the inner cores, the filling material and the outer conductor are prepared by an excellent conductor material, and the inner insulation layer is prepared by an insulation material. During AC transmission, free conductive electrons flowing in the outer conductor are uniformly distributed generally, so AC resistance of the outer surface of the outer conductor is reduced, electric energy loss is reduced, the outer conductor fully performs the conductor effect, and the conductive performance and the utilization rate of the conductor are greatly improved.

Description

technical field [0001] The invention relates to a conductor which can reduce its own AC resistance, improve its utilization rate in AC power transmission, and has multiple inner cores twisted into bundles, belonging to the field of AC power transmission. Background technique [0002] At present, in the field of AC power transmission, there is a "skin effect" in the process of AC power transmission. The skin effect refers to a phenomenon that when there is an alternating current in the conductor, the alternating current flowing inside the conductor is unevenly distributed, and it is concentrated on the outer layer of the conductor (considered "skin") to flow. It can be seen from actual use that the skin effect makes the actual current inside the conductor smaller, and the current is concentrated on the outer layer of the conductor. As a result, the AC resistance of the free conductive electron flow in the outer layer of the conductor is increased, and the electrical energy lo...
