Electrical power system for traverses in exhibition and stage construction

摘要

The invention relates to an electrical line system for trusses in trade fair and stage construction, according to the preamble of claim 1. In order to simplify the cable laying considerably on the one hand in a truss construction and on the other hand to take into account the safety-related aspects of grounding, the invention proposes that the electrical lines within one from the crossbar separate or separable with a longitudinally enclosed housing busbar are arranged with plug contacts arranged at the ends, and that the busbars are provided with integrated mechanical, electrically conductive and grounded fastening elements, such that a positive earthing of the crossbar system by fastening the busbar to the crossbar given is.
