The features of the Tubular Hydro Turbines (Bulb Turbines):

They operate in a head range of 2 meters to 30 meters and are primarily used for electrical power production. The power output ranges from 35KW to 8700KW, Runner diameters are between 0.8 and 3.3 meters. The max efficiency is up 89%.

* It has large overflowing, good flow characteristic and high efficiency etc. merits. 
* The runners are fixed or can adjust manual the efficient turbine of this kind can produce a large quantity of water flow which passes unimpeded. 
* All are horizontal type, the water enter into the turbine along the axial direction. 
* Compared with vertical axle flowing type units, the factory building is little in excavating amount, and hydropower station water conservancy project investment can save 10%- 20%, equipment investment saves 5%- 10%.

ADDNEW's Tubular Hydro Turbines (Bulb Turbines) is widely used in low water head but high water flow hydro power station.
