Re the comment that cities do not have lots of Pylons.. do any of you recall that lots so were re-routed in London because of the construction and aesthetic requirements of the Olympics stadium .
Cities have loads and loads of pylons it's just that you can't see them for the buildings most of the time.

 If you get a big OS map of London or any big city and out lying areas you will see massive spider webs of pylons branching out from the power stations & ending at local  substations  .
 The cables from the main sub-station to Queensgate shopping centre sub -station in Peterborough ran about 450 mtrs underground . They were a good 10 inches in diameter and had to be winched and pulled into position . I'm not sure if each cable was a single phase or the 12 or so cables that came into the centres substation were three phase jobbies .
