Turbine ya S-Type Tubular, yomwe imadziwikanso kuti shaft-extension turbine, imagwiritsa ntchito makonzedwe ozungulira a axial. Chinthu chodziwikiratu cha kapangidwe kake ndichakuti ma guide vanes amakonzedwa pa 65° kufika pakati pa unit, ndipo njira yowongolera madzi yozungulira a axial imagwiritsidwa ntchito. Njira yoyendetsera madzi yozungulira ya S-Type Tubular Tubrine imapangidwa ndi chitoliro cholowera, mphete ya mpando, njira yowongolera madzi yozungulira, chipinda chothamanga, cone ya tailrace, chigongono cha S-type draft ndi tailrace. Njira yoyendetsera madzi ya S-Type Tubular Tubrine ndi axial, ndipo madzi amayenda motsatira mzere wa turbine kupita ku runner.
