I-S-Type Tubular Turbine, ekwaziwa ngokuba yi-shaft-extension turbine, yamkela ulungiselelo lwe-axial oluthe tye. Isici esicacileyo sesakhiwo kukuba i-vanes yesikhokelo ilungiselelwe kwi-65 ° ukuya kumgca ophakathi weyunithi, kwaye i-axial conical water guide mechanism isetyenziswa. I-S-Type Tubular Tubrine flow flow channel yenziwe ngombhobho wokungena, isihlalo sokuhlala, i-conical water guide mechanism, i-runner room, i-tailrace cone, i-S-type draft elbow kunye ne-tailrace. Umjelo wokuhamba we-S-Type Tubular Tubrine yi-axial, kwaye amanzi ahamba ngokuhambelana ne-axis ye-turbine kwimbaleki.
