These three-ought copper wires have ancient copper tube splices in them making me think they are original conductors dating from 1906. All of the references I know of mention aluminum conductors so I'm curious if these are original conductors. The conductors are sagging extensively between the poles... as a lineman I have never seen three-ought copper wire in use on what I guess is 110k phase to phase transmission. Copper is very heavy so this might be the correct sag for this huge cable.

This line is a very high amperage circuit. All the other lines are probably being pushed to their limit; a reason why these towers have not been taken out of service and replaced. The power company simply can't reroute the power for this circuit.
