They also work for large birds. We have a river crossing where
Pelicans seem to make a habit of flying into the mains, they cause a
short and kill themselves and the power in the area. A few of these
balls seems to have fixed the problem.

I have looked everywhere,

What are the large red speres you see on high tension wires?

One set specifically where I-95 crosses the Connecticut river.




I've also heard that they (the balls) help dampen the swayof the wires in
high winds.
