Damping spacer for bundle conductors of high voltage overhead electric lines with optic fibres cable inside the bundle

摘要

The present invention concerns a damping spacer for bundle con­ductors of high voltage overhead electric lines, particularly for a bundle of electric sub-conductors inside which there is positioned an optic fibres cable. The spacer comprises a stiff body, onto which there are hinged a plurality of support arms, each through a springing hinge, to the end of each arm there being associated a clamp for connection and anchorage to each sub-conductor of the bundle. The stiff body has a nonsymmetrical configuration, eccentric in respect of the central axis of the bundle of conductors, which leaves free the central zone of the bundle. The stiff body also carries at the centre a hinge for a supplementary rocking arm, the end of which projects towards said central zone of the bundle and carries a connection clamp for an optic fibres cable.
