<p>An overhead electrification line cantilever assembly, for a rail line or other transport roadway, e.g. tram way, includes a catenary wire support arm 30 having a catenary wire fixing point 32. A registration arm 36, having a contact wire fixing point, and registration bracket 34 are coupled to the catenary wire support arm. At least one of the catenary wire support arm and the registration bracket is formed from an electrically insulating material, for example fibre reinforced plastic (e.g. glass reinforced plastic). The catenary wire fixing point may be formed of the electrically insulating material. The support arm may be provided with a further electrically insulating coating, such as PTFE or silicon rubber. A tie bar (28, fig. 2) or support prop 38 may be provided and may be formed of the electrically insulating material. The registration bracket may be coupled to the catenary wire support arm in one of both a push-off (dashed lines) and a pull-off (solid lines) configuration.</p> |
