MV OHL
(OP)
hi every one
if I have a 13.8 kv MV OHL
the total length of it is 110 km
and after 60 km the voltage droped from 13.8kv to 11kv
is it possible to install transformers that its primary voltage is 11kv after 65km?

You could add shunt capacitors as suggested by davidbeach or use voltage regulators on the line at the point where the voltage drop is too high at heavy load.
110 km is very long for a MV line. Besides unacceptable voltage drop, your line losses will be very high.

Place caps as/where needed to maintain an approximately flat voltage profile at no load. Then install voltage regulators as/where needed to maintain an acceptable voltage profile at full load. If you have no tapped loads you can get away with a less flat voltage profile; if you have tapped loads all along the line you will need more control points.
