I’ve seen this phenomenon many times over the years, while walking the dog out behind our house. The cables wiggle between these two particular power poles, but NOT between the adjacent poles (or any others, along this pole line). There is no wind, no earthquakes, no herds of animals or large vehicles/machinery anywhere nearby when this is happening. I honestly have no idea why this happens sometimes. Thoughts? I mean, sure, it’s probably ghosts, right? But any other explanation would be appreciated…

    Look up the following: “aeolian vibration“.

    This is most likely due to a differing tension between that span and the spans on either side of it. It has more “sag” (even if only fractionally different) therefore it is more susceptible to what I referenced above.

    I assume that line is communication, and the tension on them is enormous. Did you happen to get a closer look at the spiralling on it? I can’t tell by this video if it’s armouring or a grip.
