Overhead cable has to be resistant to sunlight, as well as unpalatable 
to cockatoos. It is also vulnerable to brushfires.

On a visit to Samoa, I saw ordinary blue "Ethernet" cable stung from 
power poles in the capital city. This was deteriorating after a few 
years in the tropical sun: http://www.tomw.net.au/2005/emuseums/

I also have seen cockatoos systematically destroying electrical 
equipment on power poles and cables melted in brushfires.

Transact procured special UV protected (and presumably unpalatable) gray 
cable for their overhead system in Canberra. But there was not much they 
could do about the brushfire problem.
