MAIN BUS BAR AND BRANCHESMain bus bar in flat electrolytic copper bars have standardized sections for rated current 400-630.800-1250-1600-2000 A. Theymay be realized with air insulation or (on request) with a resin insulating coat.Usually bus bars are supported by all-bearing insulator above the bus bar switch disconnectors, resistant to thermal shockand electro-dynamic stress.METALLIC STRUCTUREThe main bus bar usually pass from onecompartment to the next without break in The cubicles ’ structure, self-supporting, is composed of standardizedorder to form a continuous conduit.elements in steel sheet medium moulding, minimum thickness 20/10The branches are realized as main bus bar mm. The main elements of the structure, fitted with modular drillings, areand sized according to the rated current of assembled together by corner joints welded and special screws that ensurestrength and electrical continuity. On the structure are applied steelthe related equipments to which they arelinked.panels with a thickness of 15/10 mm.The joint areas are properly treated or (on Internal accessories, supporting panels and rubbing parts, nuts andrequest) silvered.bots are all galvanized and passivated.30
