Oops,
Sorry guys, I missed the 2 from the end of the end of the 16mm part.
This is the csa of the wire, not the diameter.
The reason for the work on this pole was to correct a problem that you can see in the centre-bottom of the first pic, where the Service Line Cable (16mm2 3 Core + Neutral Screen) runs up the pole, but some idiot had installed an anti- rodent band over the cable, which had started to eat into the cable, but don't ask me how.
So it's now sporting a pretty orange 50mm conduit run up the side of the pole.
I had intended to get a couple of close up shots of the transformer and an "after" shot, but I ran out of time and besides, the people were looking at me taking pictures of the pole when I first got there, through their kitchen window.
At least it was a nice day!.
