Instruction Manual
- After confirming the CVT is in vertical
position and supported in the ground,
change the lift system by four slings
placed at the four lifting holes of the
basetank. Use a 1.5m sling to connect
the other slings at the height of the
insulator neck to guarantee the CVT will
not move horizontally when lifting.
CVT handled with its package:
To lift the packaged transformer with
crane or munck follow the marks on the
wood crate, once it indicates the right
position for the slings (nylon belts
reinforced) and
vibrations. Handle with care!

Example of lifting the CVT on its packing
 Placing the CVT on the pedestal:
The use of lifting slings or steel cables
with a chocker type hitch arranged to
support the upper metal flange is an
effective way to lift the upper modules
of the CD.
Avoid sudden CVT movements when
lifting. To avoid CVT tipping, it is
recommended to use a sling passed
around the upper flange of the insulator
and attached to other slings (one on
each side - see figure below).
If the CD of the CVT has more than one
section, the top and bottom modules
must be joined using the supplied
material:
 Eight or twelve sets of bolts, nuts
and washers for each CD.
For OTCF having manometer in the
CD:
The display box of the manometer used
in the sections of the CD are partially
filled with liquid glycerin in order to
avoid any damage due to impact during
transportation. The glycerin is not
necessary after transportation.
On the top of manometer, there is
rubber cover with a small protrusion. For
