To improve the feasibility of small power plants standardized units were developed. The bulb turbine technology as well as the pit-type conception improve the feasibility of larger plants. Especially the pit-type turbine technology is attractive for very low head power stations. In this paper, the application of axial type turbines in low head power plants is discussed, f.e. bulb, pittype and tubular turbines. The conceptual layout and some important design features of the above turbine types are described. Typical applications in hydro power stations in the United States are demonstrated.
