TECHNICAL SPECIFICATION AND BASIC INFORMATION
- This is for information only -
MAVEL TECHNICAL SPECIFICATION: KAPLAN BULB TURBINE
1.1. Turbine Description
The Mavel Kaplan Bulb turbine is a double regulated turbine, connected to a vertical generator by a
bevel gearbox. The bevel gearbox is installed inside the turbine casing and transmits the turbine power
to the generator.
The Mavel Kaplan Bulb is a compact design solution, which has the following advantages:
e Reduced powerhouse size requirements
e Optimal hydraulic parameters
e Easy operation and maintenance
The main turbine parts, gearbox, and generator are located on top of the turbine casing and shown in
the 3D model below:
