David,I'm not entirely sure, but they could be small weighted dampers, designed to stop the cable from resonating when there is a wind across the wires.They are usually placed at intervals over the entire length of the cable and are only usually installed where there is a regular cross wind.I can't find a product picture to match those in you photo though... Cheers Derek
Vibration dampers to kill aeolian oscillation are usually a lot bigger and heavier, too.
Are they solid? or do they have a hole in the bottom. Are they some sort of "monitoring" or "jumper connection" point? Maybe for connecting to a portable transformer or genset that would be parked under the line?
Do you only see them in connection with a disconnect switch?

To keep the moderators happy, you may want to send your response to me directly and off-list. ;^)
