Suspension for an overhead electrification plant for railway lines or similar

摘要

An overhead electrification plant for railway lines, or similar, comprises at least one electric wire (9), the so-called contact wire, to power an engine, extending in a predetermined position along the railway line, and being held up by a plurality of suspension elements (3) arranged at predetermined intervals. The suspension elements (3) are at least partially composed of complex metal structures (4, 6, 7, 8) in the form of a polygon, and supported by fixed lateral standards (1) so as to project therefrom. In at least some sections of the track (B), the suspensions have equal and constant geometries, i.e. the suspension elements (3) are similar in the geometrical sense, whereas the only variable is the different overall transverse extension of the suspension elements (3) in the different points of the railway track (B).
