on this photo on bottom "conductor" or cable what the person is working on that is commuation cable .
let start from the top lines the top line is primary hot line useally 13.8 KV or 24.4 Kv [depending on local spur]
next line below the hot conductors is the primary netural line
third and fourth line i belive it is televison cable line
the bottom most line is telephone or telecomuattion line [ this is very typical for commuation line to be below of power system but offhand i am not too crazy with televison cables i heard some horror story about it ]
Merci , Marc
