I-S-Type Tubular Turbine, eyaziwa ngokuba yi-shaft-extension turbine, isebenzisa ulungelelwaniso lwe-axial oluthe tye. Uphawu olucacileyo lolwakhiwo kukuba ii-guide vanes zibekwe kuma-65° ukuya embindini weyunithi, kwaye kusetyenziswa indlela yesikhokelo samanzi e-axial conical. Itshaneli yokuhamba kwe-S-Type Tubular Tubrine yenziwe ngepayipi yokungena, iringi yesihlalo, indlela yokuqondisa amanzi e-conical, igumbi lokubaleka, ikhowuni yomsila, i-S-type draft elbow kunye ne-tailrace. Itshaneli yokuhamba kwe-S-Type Tubular Tubrine yi-axial, kwaye amanzi ahamba ngokuhambelana ne-turbine axis ukuya kwi-runner.
