    There's nothing on page 6 that is germane. Typo?

    Not sure what you mean by "the existing lines are not appropriate for high voltage transmission". If you look at the chart on page 4 of your document, you will see that 230 kV, 345 kV, and 765 kV all use the exact same cable: ACSR 954 mcm. They just use a different number per phase.

    The point of the article linked to in the diary is that existing towers could be retrofitted to carry more power at a higher voltage. Using traditional technology, you would have to tear out the tower and build new to step up to a higher voltage.

      but on page 4 the table shows that the 765 kV line (I must be higly dyslexic today - since that's where the 4 went I needed for the page number - into the 745 kV I stated earlier, ugh!) requires a "4 conductor bundle"  (and the newer, more efficient designs use a "6 conductor bundle) whereas lower voltages use a "2 conductor bundle"

      So, maybe the cable is the same in all cases, but it seems to have to be configured differently to move the super high voltages . . .
