hydraulic unit
A hydraulic unit (from a hydraulic ... and an aggregate) is an aggregate combining a hydroturbine and a hydroturbine generator as separate complete devices, together with their auxiliary systems.
Distinguish horizontal axial and vertical hydraulic units.
Horizontal axial hydraulic units are divided into direct-flow units and submerged.
The latter include capsular hydrogenerators and mine ones with a top and bottom location of the generator .
