ABSTRACT:
An electric current conducting bar of generally X-shaped configuration in transverse cross-section for use in an electric transmission system wherein a plurality of said bars of modular lengths, jointed in longitudinally alined end-to-end relation by various coupling assemblies, are fitted with insulating sheaths of generally inverted U-shape, also of modular lengths, which protectively cover not only the conductor rail per se and their coupling assemblies but also the current collector shoe which moves in electrical contact with the bar without any utilization of the insulating sheath primarily as a guide for the collector shoe. In a modified form of the X-shaped bar, the upper branches thereof are extended horizontally outward from opposite sides of the mid-section of the bar to provide the latter with a flat top having opposed longitudinally extending edges which are respectively accommodated in opposed longitudinally extending inner grooves formed in the insulated sheath. Although these inner grooves of the insulating sheath have no function in respect to the bar of the full X-shaped cross-section, the sheaths are formed to include said inner grooves so that the sheaths are of a universal form adapted to be applied to either form of the conductor bar.
