FIELD: electrical engineering; conducting bus systems for switchgear cubicles.
SUBSTANCE: proposed multiple-line bus system has one or more spatially and electrically parallel current conductors per line (per pole or phase). Current conductors are installed in bus holders made of parallel bearing parts in the form of insulating strips and their fastening means. Current conductors are partially disposed between bearing parts and partially outside the latter. Such arrangement provides for stepped disposition and easy access to switchgear cubicle from its front end. Bus holders made in the form of strips of different sizes are suited to different configurations of current conductors.
EFFECT: facilitated manufacture, reduced cost, and enhanced strength of bus holder.
