Abstract: A longitudinal, generally parallelepiped electrical conductor bar, having a generally rectangular cross-sectional area having two sides and two ends, a substantially arc-like portion extending from one corner to an adjacent corner of that area, the arc-like portion defining two complementary sections, a first whose perimeter includes the arc-like portion, the two ends and one of the two sides, and a second whose perimeter includes the arc-like section and the other side, with parallel, elongate bores extending through the length of the conductor bar.

Abstract: An improved bar has been developed for current conduction. In particular, its cross-section has been designed to limit the quantity of material necessary to transmit a given rated current. The material is mainly located on the same side as the surface containing the connecting groove and the contact tracks. The use of this type of profile enables losses by Joule effect to be reduced, for an equivalent cross-section, and aluminium to be used for example for strong amperages. The solution enables fast erection and electric connection and is suitable for high-amperage and/or three-phase currents.

Abstract: A busbar device with an insulating support block with two assemblable fixing parts bounding internal housings to receive multipole current conductors, each housing being formed by a semi-open recess. The bottoms of the recesses are located in distinct planes extending in a parallel manner along the longitudinal direction of the profiled sections, and separated from one another by a predetermined transverse pitch, and the profiled sections of the current conductors are staggered at regular intervals in the extension direction of the assembly interface of the fixing parts to form a stepped structure.
