UPDATED METAL TRANSVERSE PROFILE FOR FEEDER SWITCHBOARD CASES Russian patent published in 2008 - IPC H02B1/30 

FIELD: electrical engineering, mechanics.

SUBSTANCE: metal transverse profile contains transverse profile (104) with its outer side accommodating the supports for partitions and fasteners and inner part furnished with vertical electrical and electronic components mounts. The transverse profile represents a certain-shape transverse section in the rectangular triangle geometry, its sides forming the inner section or central base in tubular geometry (105) and vertical element (106) facing the inside of cabinet (100). The opposite vertical element (107) faces the outward side of the said cabinet (100), while two other adjacent vertical elements (108) feature a geometry formed by walls (109) making direct angle (106). The walls making the aforesaid vertical element (107) are bent perpendicular towards vertical element (107) and, thereafter are bent inwards to form U-like (110). The length of walls (111) features a sequence of various-angle bends. The vertical element passes outwards to form mounting shoulder (112) whereon abut two continuous walls (111) outside cabinet (100). Walls (109) stay inside cabinet (100) and are furnished with rows of holes varying in shape and size (113). Mounting wall (112) is also furnished with the rows of various holes (114) to attach the outer elements to cabinet (100).

EFFECT: higher operating reliability.
