They are earth wires so that lightning hits these before the main AC wires: -

Oh, awesome. But isn't the tower a natural grounder, wouldn't a lighting hit the tower anyways?
Or is it to protect the lines between tower-to-towers

It's not to protect the tower - what would protect the lines between towers if lightning hit? – Andy aka Apr 24 '18 at 13:29

Cool, so it's to protect lines between towers – mateos Apr 24 '18 at 13:44
Yes it is - it acts like a poor man's "faraday cage". – Andy aka Apr 24 '18 at 13:46

@copper.hat, You wouldn't see very many of them if they didn't save somebody some money in the long run. – Solomon Slow Apr 24 '18 at 14:43
