FIELD: mechanical engineering. SUBSTANCE: device has bedplate with bath filled with electrolyte and anode inside it. Current lead cathode system is in the form of several flexible bus-bars positioned in parallel to each other. Each bus-bar is formed by weave of several filaments of electroconducting material. Bus-bars envelope neck of roll along the generant. One end of each bus-bar connected to power supply source is rigidly attached to bedplate via dielectric gasket. Another end of bus-bar is connected to tension jig. Adjustment of tension of bus-bars leads to increase of area of contact of conductor with neck of roll. EFFECT: enhanced operating capability. 3 dwg
