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.

Abstract

An electrical train messenger wire and a catenary system for an electrical train including the electrical train messenger wire. The messenger wire includes a fiber-reinforced composite strength member and a conductive layer surrounding the fiber-reinforced composite strength member, where the conductive layer is fabricated from copper or a copper alloy. The fiber-reinforced strength member advantageously has a high tensile strength, thereby reducing the sag of a contact wire supported by the messenger wire. The catenary system employing the messenger wire may facilitate faster train speeds and may obviate the need for cantilever systems such as balanced weight anchors to maintain tension in the contact wire.

Abstract

A conductor for overhead power transmission is described which comprises an elongated core built up from a core material and an elongated conductive sheath constructed from a conductive material, the conductive sheath typically being located around the core, but separate from the core. The thermal expansion coefficient of the core material is lower than the thermal expansion coefficient of the sheath. Between the core and the conductive sheath there is a resilient, elastic material, adapted to, by means of dimensional changes, compensate for dimensional effects due to tension differences between the core and the conductive sheath in the finished conductor.
