Here in the civilised world we bury the wires ;-) Even the long-haul 765kv and up connections across the power grid?
In the US, they're out on towers for a reason - you can fly along them in a helicopter and easily spot parts of cable that are degrading and need repair because they glow brighter on an infrared scope...
(Plus, as Hurricane Sandy taught Manhattan, buried wires have their own rather nasty failure modes....)
Right and here in California, it was precisely those lines that incinerated Paradise. The problem with PG&E is that they couldn't be bothered to maintain anything since it got in the way of cushy estaff salaries and investor dividends. The tower that caused Paradise was a century old. Mike
