Patent number: 11745624Abstract: 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.Type: GrantFiled: December 12, 2016Date of Patent: September 5, 2023Assignees: CTC Global Corporation, Lamifil NVInventors: Eric Bosze, Peter Hermans
