The four „bűibe" type tubular turbines have been manifac- tured in Neypric—Ganz-MAVAG, French—Hungarian co-operation. This type of tubular turbines works well in the French low- head hydroelectric power-stations because of their need for narrow concrete block and their good flow and efficiency characters. The four generators manifactured by Altstrohm—Ganz Electric Works in French—Hungarian co-operation, are built on joint shaft with the turbines. Their type is Altstrohm RV—389—72. The shafts of the turbine rotors are placed at a distance of 11,5 m from each other at El. 75,55 m A. O. D. The wheel discharge capacity is 4X140 = 560 cu. m/s under the rated head of 6,27 m and the generators produce 4X700 = 28 000 kWh output. The horizontal-shaft generators work on 2,5 kV voltage level and the 103 million kWh power generated as a yearly average by the four turbines, is fed through two transformers characterized by 2,5/20/120 kV and 14/14/14 MVA outputs, to a 120 kV, and to eight 20 kV grids connected to the switchyard for the consumers. The transportation of the mechanical equipments into and out of the power house is made possible through the top ceiling openings of the power house, which are closed by removable elements. The turbines start working at 2 m head, the maximum head being 10,7 m. In flood operation the water can flow through the turbines without power generation at a head less than 1 m. The dewatering needed to the repairs and the control of the turbines is made possible by up and downstream panels.
