ABSTRACT:
A duct for electrical cables comprises a plurality of filiform elements arranged substantially parallel to one another according to the longitudinal development of the duct. The duct of the invention includes, for at least a portion of its length, a plurality of structural modules, which are arranged in a transverse direction with respect to said filiform elements and are set at a distance from one another in succession according to the longitudinal development of the duct. The supporting modules have a basically U-shaped body that includes a central wall from which there project, on opposites sides with respect to one another, two side walls that are set substantially parallel to one another. On said shaped body coupling means, designed to enable connection with said filiform elements, are arranged.
