摘要:
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.

A wire includes a plurality of carbon nanotube infused fibers in which the infused carbon nanotubes are aligned parallel to the fiber axes. An electromagnetic shield for a wire includes a plurality of carbon nanotube infused fibers, in which the infused carbon nanotubes are aligned radially about the fiber axes. The plurality of carbon nanotube infused fibers are arranged circumferentially about the wire with the fiber axes parallel to the wire. A self-shielded wire includes 1) a wire that includes a plurality of carbon nanotube infused fibers in which the infused carbon nanotubes are aligned parallel to the fiber axes; and 2) an electromagnetic shield that includes a plurality of carbon nanotube infused fibers in which the carbon nanotubes are aligned radially about the fiber axes. The axes of the carbon nanotube infused fibers of the wire and the carbon nanotube infused fibers of the electromagnetic shield share are parallel.
