Bracket systems for control equipment, command enclosures and similar equipment are formed from units that basically include a support section for bending and torsion stability and a channel profile section for receiving cables. Th e support section is in the shape of an double T integrally comprising a central vertical bridge, an upper horizontal bridge and a lower horizontal bridge, with the vertical bridge being enlarged at its junction with the upper horizontal bridge into a longitudinal, cylindric torsion rod. Vertical thin walls extend integrally and partially upwardly from the lower horizontal bridge and are spaced apart from the central vertical bridge thereby forming empty spaces that act as channels for receiving of cables access openings that exist above said vertical thin walls, and there are cappings engagable with the vertical thin walls to close the access openings. Longitudinal bore s in the double T structure receive fasteners to fix together a multiplicity of the system units. |
