Abstract
The present invention provides an improved catenary wire system for an overhead line equipment (OLE) installation. Known OLE installations are prone to sagging and hence require a large number of support structures, which are expensive to install and maintain. These structures also appear “cluttered” and ungainly. The catenary wire system of the present invention comprises a fibre reinforced composite catenary wire configured to suspend a contact wire; and at least one elongate electrically conductive element arranged generally parallel with the catenary wire. It has been found that the catenary wire system of the present invention is able to withstand increased tensions when compared to known OLE installations, which reduces the amount of catenary wire sag, and can thereby reduce the number of support structures required by an OLE installation.
