That is VERY cramped for a 115kV transmission line, don't you think?

Wow. Those post insulators just look HUGE! Sure looks a bit odd on an old 41.6kV crossarm.

Seeing 115kV lines like this is very strange to me as I'm used to seeing 115kV on large H-frames or 150-foot towers, instead of on little poles like this!

I do like the look of these 115kV poles from Ottertail though. How many do you think are still on this line?

These cramped poles are only within the Alice city limits (3-4 blocks). Elsewhere it's the wider spec, but even those segments have poles that have been replaced with ones having horizontal posts - first with porcelain and more recently polymer.

I've got to wonder how those crossarms hold up with those massive posts on them. I guess the posts share bolts with the crossarm braces though, which should help a little bit.

That still looks so weird to me. Over here most 115kvs are mounted on H-Frames or steel and concrete monopoles with pole mounted insulators.

Most of the 115kV lines out this way are as you describe (H-frames or monopoles) - it is just a few specific lines where Otter Tail needed to run 115kV between certain points and where there already was a 41.6kV line along the same path, so they just converted the 41.6kV.
