I wonder if some one out there knows what the round ball looking attachments
are that they put on the power lines in an area here in Austin Texas. These
are on the power line wires along the freeway near a military installation
were I see aircrafts (planes and possibly helicopters). Would these round
objects have been placed on the power lines to mark their locations so the
aircrafts don't hit them or possibly direction markers for the aircrafts?

Most likely warning markers for aircraft. Power lines can be darn near
invisible against other ground objects when seen from above.

But I've also seen such balls put on lines temporarily near construction
sites that use cranes a lot. Provide some extra visibility for the crane
operator to avoid them.

You are right. They mark the lines for aircraft. Very common in
mountain areas, such as Colorado, where the lines span canyons.
