I-S-Type Tubular Turbine, eyaziwa nangokuthi i-shaft-extension turbine, yamukela ukuhlelwa kwe-axial evundlile. Isici esisobala sesakhiwo ukuthi ama-vanes omhlahlandlela ahlelwe ku-65 ° kuya kumugqa omaphakathi weyunithi, futhi kusetshenziswa indlela yokuqondisa amanzi eyi-axial conical. Isiteshi sokugeleza se-S-Type Tubular Tubrine sakhiwe ngepayipi elingenayo, indandatho yesihlalo, indlela yokuqondisa amanzi eyisiyingi, igumbi lomgijimi, ikhoni ye-tailrace, indololwane yohlobo lwe-S kanye ne-tailrace. Ishaneli yokugeleza ye-S-Type Tubular Tubrine iyi-axial, futhi amanzi ageleza ngokuhambisana ne-axis ye-turbine kumgijimi.
