Abstract
In lightweight fabricated equipment of an overhead electric traction system, (e.g., section insulators and neutral sections), comprising at least one tension insulator mechanically connected between and electrically insulating from one another two elongate metal members, in at least one mechanical connection between the tension insulator and elongate metal member, an insulating end part of the tension insulator and an end part of the elongate metal member butt or are spaced apart and have a supplementary connecting member connected to them by separate securing bolts. The undersurfaces of the end parts of the tension insulator and elongate metal member and the undersurface of the supplementary connecting member constitute a smooth running surface.
