Electric energy distribution system for low voltage electric boards and cabinets

摘要

A system for the distribution of electric energy for low voltage boards, in particular for amperages higher than 630A, comprises parallel conductive bars (1) connected to a supporting structure (2) with connecting and locking means (5) and interposed insulating supports (6), wherein said conductive bars (1) are placed on vertical parallel planes spaced and at different height levels according to a stepped arrangement. The different height levels may have an increasing or a decreasing trend. Alternatively, the two arrangements by different height levels having and increasing respectively a decreasing trend may be arranged especially with respect to a horizontal plane or facing one another. Such arrangements of the conductive bars (1) allow not only an easy maintenance and an easy control of the locking elements, but also a reduction in the bending stress and therefore the deformation to which bars are submitted in case of short circuit.
