The big insulators are power, the uninsulated bare wires are power lines. The big terminals on the transformer box are a give-away.
The insulated stuff is probably telephone cable, the larger multi pair, some of it appears to be single pair drop wire. In all probability, a lot of it is old and unused, not having been removed when a replacement length was inserted, probably because of the high probability of damaging working stuff by removing it. When there is enough, it will probably serve to keep the rain off the street.
