They've certainly been the norm here for a very long time. Here is another single-phase xfmr, this time feeding 3-wire 240/480V local distribution lines in a rural area where there are a few dozen homes scattered along a backlane (primary is 11kV again):

The typical 3-phase xfmr looks very similar, although obviously with 3 HV bushings and 4 LV terminals.

We've started seeing one or two new types in the last few years though, like this cylindrical unit which is much more North-American-looking:

Or this one, which at first sight seems odd for having the HV bushings vertical instead of at an angle like almost all of our older xfmrs:

Do aerial transformers in the UK typically have primary fusing or cutouts?


There's not usually any fusing on overhead xfmr connections here. Cut-outs and sectionalizers can be found in some places.
