I just made pulling caculations for your installation using the following:
1 90 degree bend 4' radius
1 1300 ft straight run of 3" pvc
1 90 degree bend 4" radius
Caculations show no problems with the pull.
Rome Cable make a URD type cable #2 CU 15kv, .175 mils insulation, condentric neutral and PE jacket overall that will do the trick. If you do not know how to install the elbows, hire someone who does. It won't last if the installation is wrong.
Most Utilities use AL cable.
