A possibility for their use is suggested by the small "globes" at the free ends of the conductors in the 2nd photo. If this array of conductors was intended for lightning protection, they better would have very sharp tips in order to reduce the flashover voltage appearing at the ends of the conductors. Also, ~vertical conductors would be better ...
