electrical engineering; metal-clad switch-gear, stations, and substations. SUBSTANCE: axial force required to maintain desired pressure at collet-type contact joints is ensured due to weight of draw-out circuit-opening device. To this end, module is built up of three parts: stationary part, movable, and fixed assemblies of draw-out part. EFFECT: improved reliability of contact connection. 9 dwg
