Rectangular tubular conductor busbar with solid core and internal heat dissipation

Abstract

The invention relates to a “rectangular tubular busbar with a solid core and internal heat dissipation” having a rectangular tubular shape, used in electrical cabinets for low- and high-voltage power control and regulation assemblies and prefabricated power lines, the main structure of said busbar comprising a tubular rectangular busbar (P) having a substantially parallelepiped shape, said busbar having a body (1) bounded by outer walls, a solid core (2) formed by the superposition of elements, this triplet, in terms of the thickness of the walls forming the body (1), being located between the upper and lower walls of said body (1), said rectangular tubular bar (P) having two distinct regions, a hollow zone (A1) and the solid web (2), the region of the hollow zone (A1) being bounded between a rear face of the rectangular tubular bar (P) and the upper and lower faces of said tubular bar (P), and the solid web (2) being located in the region bounded by the front face of the rectangular tubular bar (P) and the upper and lower walls of said rectangular tubular bar (P), as well as the hollow zone (A1).
