Hydro Power Products

Hydropower Turbines and Generators
For hydropower, the selection of turbine type, generator and balance of plant technology are quite different in every case. There are no off-the-shelf solutions. Every equipment shall be tailor-made based on the conditions of each site such as the water head, water flow and plant configuration.

TELLHOW has developed high efficiency hydropower turbines. The turbine diameter of the product we can offer is 40-600cm, which is suitable for the water head of 2.3-1000m. The highest electricity generated is up to 50MW per unit.

Hydroelectric Generators

Features
A hydroelectric generator is an electric rotating machine that transforms mechanical power from a hydraulic turbine or water turbine into electric power. The product we offer may have a horizontal or vertical shaft. The horizontal units are usually small with speed from of 300–1200 revolutions per minute (rpm). The vertical unit is usually larger and is more easily adapted to small hydraulic heads.
