1. Water heads from 2m to 20m and large discharge.
2.It has the high efficiency .

Tubular turbine and Bulb turbine is suitable for heads from 2m to 20m and large discharge. lts feature is that the water flow is axial throughout the passage from the inlet to the outlet, so that the passage is a straight conduit essentially. The tubular turbine is characterized by good characteristic of water flow and high efficiency etc.
