Pelton turbine is one kind of impulse turbines,used for high-head (50m~1300m) power plants.our company has streamlined the contraction of the nozzle; the energy can flow efficiently into kinetic energy of high-speed jet. While the turbine changes in the load, the water inlet speed and direction keep the same. Pelton turbine changes in a relatively small head, speed, efficiency and therefore the efficiency changes less while the load changes , the maximum efficiency can excess 91%.
