Power conductor rail

摘要: In accordance with the present invention, a power conductor rail structure is provided using multi-metallic construction. The composite of invention includes an asymmetrical steel portion having top flange thickness greater than that bottom in generally I-shaped configuration spaced apertures along length web. Aluminum cladding cast onto both sides web cold rolled high conductivity layer, such as copper disposed between aluminum and on either side holes corresponding size shape to extends through producing sandwich layers provide mechanical bond reduces transfer resistance increasing overall conductivity. alternative embodiment formed openings filling so forms part electrical contact surface, one by additionally forming continuous, longitudinally extending, filled groove surface rail.
