The Tubular type turbines are usually the best choices for exploitation of tidal power and hydraulic power with extremely low heads and extremely large flow rates. They have the advantages such as large discharge, high flow speed, high efficiency and less excavation, etc. Their variations have Bulb, Pit, Siphon and S types according to their structural types.
The water diversion parts, runner and water drainage parts of Tubular turbine are on one axial line. The water flow directly and straightly through the runner without spiral casing. The water flow is axial from the pipe inlet to the draft tube outlet.
Tubular turbine generally has two categories: Fully tubular and half tubular. The half Tubular turbine is divided into bulb, pit and shaft extension types, etc.
The generator's rotor of the full tubular type unit is on the outer circle of turbine's runner, whose application is less because of its difficult sealing.
For half Tubular turbine, the generator is separate from the hydro turbine:
Tubular type: Generator set is installed inside the airtight bulb body, which has a compact structure, straight passage shape, high hydraulic efficiency and so it is widely used.
Shaft extension type tubular unit: The generator is installed outside, the main shaft of turbine extends to the outside of the draft tube.
Pit type tubular unit: The generator is installed inside a pit.
Application scope of heads: 2m~25m
Runner diameters: 1.0m ~ 7.2m
Installable capacity: 200KW ~ 200000KW

Found in 1958, our factory in hydropower products has continuously been one of the national strategic turbine manufacturers in China since year 1995. It has now 246, 000 square meters ground area and 68, 000 square meters office building area. With over 500 workers and over 200 technicians and engineers, ADDNEW's invested factory is certificated by ISO9000-2000 and CE.
From the start of 2005 to the end of 2012, ADDNEW and our factory in Hunan, China have designed, manufactured and installed successfully over 170 small Hydroelectric Power Stations in Albania, Chili, Congo, India, Lithuania, Kazakhstan, Vietnam, Zambia and other overseas markets. The equipments adopted for those hydropower stations are unit-capacity from 800KW to 100MW and the total power generating capacities of each station ranging from 1600KW-200MW. All the completed stations are now maintaining their peak performance after their installations.
