COMPOSITE ELECTRICAL CONDUCTOR

摘要

A pair of aluminum bars are bolted to the web of a steel rail having a generally I-shaped cross-section. The bars are contoured to fit within the recesses formed on each side of the rail to provide good electrical contact between the aluminum and the steel and a layer of conductive grease is positioned between the bar and the rail. The bars can be provided with deformable means for sealing the interface between the bar and the aluminum as the bars are drawn into engagement with the rail.
