ESB Ireland uses LOADS of those. They're all over the place once you get outside built up areas.
They use them to serve 1/2/3 homes max from 10KV distribution lines over here. They're a little squarer than that though.
Most farm houses are supplied like that here.
Pole top transformer supplying either single phase 220V or 3 phase 380 V for farm buildings etc.
Not used in the UK system normally?
I've never seen single phase distribution like that though. Even local low voltage final stage distribution is 380V each property just picks off 1 phase and neutral (domestic @ 220V) or all 3 phases & N commercial.
Sometimes there are very small ground mounted xFormers used for distribution in built up areas, kerb side box style. Rural areas are absolutely full of big/small green pole top xformers though, just like in the USA (Except green, it is ireland afterall!)
You occasionally also see larger pole top xformers mounted on a kinda wooden frame between two large wooden poles. Think they may feed a village / large farm complex.
