Rectangular tubular conductor busbar with solid core and internal heat dissipation

A RECTANGULAR TUBULAR CONDUCTOR BUSBAR constructed of an electrical conductor material or a combination of two electrical conductor materials, featuring a rectangular tubular shape, applied in electrical cabinets for low, medium, and high voltage power switchgears, and prefabricated electrical lines, wherein, in its main construction, it comprises a rectangular tubular busbar (P), substantially parallelepiped in shape, having a body (1) delimited by external walls, a solid core (2) formed by the overlapped elements, this core being triple in relation to the thickness of the walls forming the body (1), located between the upper and lower walls of said body (1);

• the rectangular tubular busbar (P) having two distinct regions, a hollow area (A1), and the solid core (2), wherein the hollow area region (A1) is delimited between the rear face of the tubular busbar (P) and the upper and lower faces of said rectangular tubular busbar (P), and the solid core (2) is located in the region delimited by the front face of the rectangular tubular busbar (P) and the upper and lower walls of said rectangular tubular busbar (P), as well as the hollow area (A1).
