Since I moved to Lynden, Washington a while back I have spotted these triangle thingies at significant angle points of pole wire runs- I've never seen these anywhere else before. What purpose do they serve? My guesses:

1) Devices for minimizing corona effects;
2) "Slow-Moving Electron" signs;
3) Metric electron discharge devices to rid the lines of those metric electrons that somehow got through the Metric/English convertors at the US/Canadian border ;
4) Something else.

As a wild guess, something to keep birds/critters off of the crossarms/lines?

Are they only on angle structures?

That is where I've spotted them- it seems to me that I may have seen some of these on one pole which was on a straight portion. But that was a definite exception.

They're in about the right location to be lightning rods. I don't see any indication that they go to ground, though.
