Apparatus for elevated suspension of an overhead electrical conductor and overhead conductor suspension structure

摘要

Apparatus for increasing electrical clearances of overhead electrical conductors to ground by means of insulator strings and jumpers. Electrical conductors (1) are attached to the support structure (13, 14, 15, 48) by a device ensuring their displacement along the direction of the line (4, 11) and insulator strings (2) arranged in a configuration resembling tension insulator strings and bridged by a jumper (7). Overhead conductor suspension structure with conductor suspension above described. The suspension is attached to the trunk (15) of the pole or inside the trunk (15), with a jumper (7) bypassing the suspension structure by means of the cross arm (13) of the pole or an auxiliary and/or insulator arm (50), or a jumper (7) passed through a suitably formed opening in the trunk. Suspension structure characterised in that supplementary arms (14) are mounted to the trunk (15) in the space freed up by the elevation of electrical conductors and supplementary electrical conductors (12) are suspended to the supplementary arms (14).
