If you are really installing a 320 mile long 110kV AC three phase cable system then you need to enlist specialist help. You are not going to get an answer on a tips forum. In my experience the normal thing to do would be to specify the voltage and rating you require (amongst other things), and the cable manufacturer/installer would design an installation to meet your specification. They would determine the number and location of phase transposition points and sheath cross bonding points. The BICC Cables Handbook ISBN-13: 978-0632040759 is an excellent general reference for all things to do with cables and explains cross bonding.

Thanks burnt2x and Marmite.
I made a mistake. The system is 32 miles long.
I´ll look in the BICC Cable handbokk.

Thanks again
