O.K., what I was getting at about this being an unusual sight is not that it's a single-phase line.

It's the point allured to in Scott's first post: The cylindrical-cased xfmr and method of mounting on the pole which look very much more American than anything else you'd be likely to see here. This is certainly the only xfmr of this type I've seen in the area, and in fact I don't recall ever seeing this type in England before. The xfmr in question looks fairly new and not badly weathered as yet, so it probably hasn't been there too long. I'm wondering if the PoCo is going to start using more of these when replacements become necessary.

Here's the more usual style of single-phase xfmr that you would see on poles to feed one or two houses:

The 3-phase pole-types feeding a 4-wire 240/415V wye system for distribution to a number of houses usually look something like this:
