Abstract
An overhead wire has a wire core having a main core and a plurality of auxiliary cores spirally and tightly stranded on the main core, and a conducting layer coating the wire core and having at least one aluminum wire layer. The main core and the auxiliary cores has fiber resin strands formed by fiber filament bundles permeated with resin through molding, and fiber filaments wound on and completely covering the fiber resin strands such that the fiber resin strand is isolated from the outside, and the at least one aluminum wire layer has a plurality of aluminum wires spirally and tightly stranded on the wire core.
Claims7
