COMPACT
BELT DRIVE BULB TURBINE
VA TECH HYDRO, a world leader in bulb
turbine design and production, has devel-
oped the Compact Belt Drive Bulb Turbine.
This concept has been designed for low
head applications where this low budget
solution offers a cost-effective way of
exploiting especially small water power.
Based on the well-proven Bevel Gear Bulb
Turbine, the Belt Drive Bulb Turbine comple-
ments the Compact Hydro Program in the low
head segment.
Modern and compact, these machines offer
many advantages and attractive design
features. Thanks to double regulation, with
controllable runner blades and wicket gates.
Compact Belt Drive Bulb Turbines make
the most of available energy through optimal
efficiency and outstanding part-load charac-
teristics. All guarantees are backed up by model
tests in the VA TECH HYDRO laboratories.
Turbine, belt drive and generator form a
compact unit which is delivered fully assembled
and shop-tested. Installation into completed
powerhouse is achieved in only one embedding
phase thus drastically reducing erection time
and costs.
The design concept of these compact turbines
likewise reduces construction costs. Minimal
powerhouse dimensions with simple intake and
outflow contours substantially reduce overall
expenditures.
