是一种适用于开发广大平原、丘陵、沿海等低水头、大流量水力资源，经济加值较高的机型。该机型过流能力大，高效区广，它与立式轴流式机组相比，效率高，厂房开挖量小，电站水工投资能节省10％－20％。
Tubularturbine is the type one of high economicvalues and is preferable to some plains,hills and coastal areas of low head and large discharge. This kind ofunits has the characteristics of high flow capacity, and broad section of high hydraulic efficiency, especially, it hasthe advantages of higher efficency and less excavation quantities and saving10%~20% cost of hydraulic structure compared with vertical Axial turbine.
贯流式水轮机适用于低水头、大流量电站，适用水头2~25m。按其结构型式分为灯泡式、轴伸式、竖井式和全贯流式等。
Tubular turbines are suitable for low head and largedischarge. Theusing head can be 2 to 25 meters.They can be classified into Bulb,S-type,.Pitand strafslo turbines according to The arrangement and structure of the units.
