Structural arrangement for use in a conducting busbar

A constructive arrangement, applied to high-current primary or secondary busbars, used in low and medium voltage electric cabinets, wherein a busbar is obtained by extrusion, profiling or bending process, in a continuous manner, wherein the busbar presents a triple wall in its lower portion, which has central holes equidistant to each other along its entire length;

• above the triple wall is a central structure, in tubular format, substantially cubic, containing a real wall in V-format, where the vertex extends inwardly of the busbar;
• just above the central structure is a double wall, which has central holes equidistant to each other along its entire length, as well as an upper flange in its uppermost portion, where the double walls are spaced apart.
