FIELD: bus wiring. SUBSTANCE: switchgear installation has several cubicles assembled together and collecting buses passed through these cubicles. Supporting members of switchgear installation have shaped grooves bent out or in to form space throughout entire length to receive buses. Supports of collecting buses are comb-shaped and have grooved to fit entire contour of buses. Such mechanical design makes it possible to place collecting buses in their respective space without drawing them, as it was in existing switchgear installations, starting from end of switchgear. New design is suited both for low-voltage switchgear provided with space for collecting buses located on top or on rear side. EFFECT: facilitated wiring procedure. 5 cl, 6 dwg
