Actually: SOME are. The highest voltage ones are
AC.
(Hint:
Some of the power i use to send this comes from Hydro-Quebec in in
Canada, via
+/-500KVDC link.
I got a tour with the local IEEE group, some years
back...

Bundling is for corona reduction/avoidance. The
'bundle' of smaller wires 'looks like', for
e-field, a conductor with a radius of the bundle.
ferinstance, the HVDC link i mentioned above uses
_bundled_ conductors AT DC...
At Tesla coil primary currents and voltages, skin
effect is starting to become noticable, expecially
for the RF component...
