It's been a while...

...So here's a twofer.



I'm really not sure what is going on here, but I'll speculate. First of all, this represents another transfer point between above and below ground power transmission. Second, I would guess that the large tanks are filled with oil and are simply larger versions of the type you typically see on local distribution lines.



No matter what these insulators are impressive.

One note though... it looks like only half the lines are attached to those tanks, and though you can't see it particularly well, there's room on the elevated platform for 3 more tanks... perhaps this means that this section of lines isn't operating at full capacity?
