Safe Harbor Kaplan turbines

ONE of the numerous features of more than usual interest at the Safe Harbor hydroelectric development is the application of the Kaplan type of automatically adjustable blade propeller turbine. This type of turbine is used in all 6 units of the initial installation, each unit rated at 42,500 hp under a rated head of 55 ft. Safe Harbor is the first installation in America of Kaplan type turbines of large capacity, although they have been used for low head developments in Europe since 1919
