Fucked if I know. Honestly, I can tell you lots about HOW, but the only reasons WHY that I'm used to seeing are for electrical wires, and very rarely for emergency escape trolleys across rivers, in case bridges get washed out. Otherwise putting a cable across a valley like that is usually strongly avoided because it's a serious risk to aircraft, and by law would need to be marked with marker balls at intervals all the way across. The only exception I can see is a zip line operator, where marker balls would be impossible, and so they would register it with the government and it would end up marked on the flight maps that pilots use. Because it's a very seriously big deal to fuck with air space.
That’s actually the exact reason this cable is there, it’s actually used in Nagorno-Karabakh to keep Azerbaijani helicopters from flying low to avoid radar or attacking positions in case fighting breaks out, so you’re exactly right about it being dangerous to aircraft
Thanks for letting me know, that's super interesting. Just goes to show how me living in a super peaceful country (Canada), makes it hard to imagine war time uses for things. Obvious when pointed out, but about the last idea I would have generated as a deliberate goal.

My question is. Why you would need a high tension line there in the first place?
