BOB V 2000 - VERTICAL WINDING MACHINE FOR POWER TRANSFORMERS
TARGET
The BOB V 2000 allows to wind disc-type coils on vertical axis, mainly suitable
then for HV windings of the largest power transformers ranging from 25 to 315
MVA.
MAIN FEATURES
The vertical winding method for disc windings, compared to horizontal winding
system allows to quickly perform the reversed disc winding with one only
operator, to have more compact coils and to have the coils ready in vertical
position for the assembly phase.
The machine does not require neither a pit nor special foundation works since it
is made up of a driving unit and a lifting platform which can be positioned on the
ground.
As option, an automatic bending device with software program will be installed
to pre-calculate the exact point of the bending, allowing a semi-automatic
winding process thus further reducing winding time.
