摘要

The casing has a frame that is composed of a set of sections (11) on which panels are fixed for defining an upper wall, a lower wall (14) and lateral walls (15). The sections (11) are provided in the form of hollow sections (16) between which a common longitudinal stop (17) is provided. The longitudinal stop (17) allows to connect the hollow sections (16) with each other. The sections (16) are formed of square transversal sections (18) that are formed by inner and outer square sections (18a, 18b), where the section (18a) is arranged inside the casing.
