Trumpy:
This hopefully is a better view for you. The top cable is a messenger that supports the insulators.

I saw that RODALCO made a video on YouTube about these power lines is it really safe on HV mains like that?

Hey thanks John (Hotline).
That explains everything, for some strange reason I'd imagined these being used in some other way.

I have seen those close bundled lines in Louisville, Kentucky, as Annemarie has seen on a YouTube video I posted.
Some parts of Kansas have those lines too. I think they are 14.4 kV and have outside insulation except the Neutral which is bare.

Rodalco:
Either 13.2 KV, or 4160 v primaries, two circuits shown in pic.

POCO recently ran new monopoles with twin (2) new 500KV from a power plant to the switchyard in the Twp I work in. They removed a run of old lattice towers for a right of way for the monopoles.
