Abstract
A conductor for power transportation includes an elongated core constructed from a core material and an elongated conductive casing constructed from a conductive material. The elongated conductive casing is positioned around the elongated core and constructed from various layers of wires. Each layer of wires consists of a set of wires which are positioned next to each other, and at least a fraction of these wires being shaped in such a way that for the cross section of the wire, a circumscribed circle is filled only with between 50% and 90% of wire material. The cross section of the wire has a central portion filled with wire and a plurality of protrusions. The shape of these wires is such that the space taken up by these wires in the stack of wires in the layers is substantially cylindrical.

A conductor for power transportation, the conductor comprising:
- an elongated core constructed from a core material and
- an elongated conductive casing constructed from a conductive material,
- wherein the elongated conductive casing is positioned around the elongated core and is constructed from various layers of wires, each layer of wires consisting of a set of wires which are positioned side by side, and
- wherein at least a fraction of these wires are shaped in such a way that in the cross section of the wire there is a circumscribed circle only between 50% and 90% full of wire material and that the cross section of the wire has a central portion filled with wire material, and the cross section of the wire has a plurality of projections with one or more concavities spaced between each of the one or more projections or the cross section of the wire includes one or more hollow portions defined by an outer portion of the wire,
- wherein the shape of the one or more projections and the one or more concavities, or the shape of the one or more hollow portions and the outer portion of the wires is such that spaces are provided between the wires that are unoccupied by the wire material in at least a portion of the one or more projections of the one or more hollows, and
- wherein the shape of these wires is such that the space taken up by the wire in a stack of the wires in the layers is substantially cylindrical.
A conductive wire, wherein the wire is shaped in such a way that in the cross section of the wire there is a circumscribed circle only between 50% and 90% full of wire material,
- wherein a cross section of the wire has a central portion filled with wire material and the cross section of the wire has a plurality of projections with one or more concavities spaced between each of the one or more projections or the cross section of the wire includes one or more hollow portions defined by an outer portion of the wire,
- wherein the shape of the one or more projections and the one or more concavities, or the shape of the one or more hollow portions and the outer portion of the wire is such that spaces are provided between the wire and a same wire that are unoccupied by the wire material in at least a portion of the one or more projections of the one or more hollows, and
- wherein the shape of the wire is such that the space taken up by the wire in a stack of same wires is substantially cylindrical.
