abstandhalte and dampfungseinrichtung for gebundelte head of electric overhead lines

摘要

A spacer for conductors of overhead electric lines has a rigid frame on which two or more arms are mounted equally spaced from each other. Corresponding to each arm, there is provided an elongated polygonal bar mounted on the frame. Each arm has a ring member having an inner surface arranged so as to substantially surround the bar - the inner surface having a polygonal cross-section with each corner of the inner surface being arranged opposite a different side of the bar. Rubber members are placed between the sides of the bar and the inner surface so as to resiliently support the arm on the bar and while the rubber members deform permit movement of the arm while being urged to a predetermined position by the restoring forces of the deformed rubber members.
