Abstract
A multi-core electric power metal conductive wire is manufactured according to the steps as follow: first, providing a plurality of solid conductive cores; next, providing a first conductive metal material with a first DC resistance to encase each conductive core to form a conductive strand; collecting and binding a plurality of conductive strands in one bundle; providing at least one sheet type second conductive metal material to encase the bundle of the conductive strands to form a conductive bus and form a connection seam between two side walls of the second conductive metal material not yet connected; forming an electric connection spot at the connection seam through a welding process; and finally providing an insulation encasing material to encase the conductive bus to finish the multi-core electric power metal conductive wire. The invention provides a simpler fabrication process and can reduce skin effect of the metal conductive wire.
