US distribution transformers are around 50 kVA, in the EU they are more like 300-1000 kVA, so they can power 10-20x more homes per transformer.
Instead of those little pole-mounted transformers that are common in the US, we have one of these buildings with a large transformer for each neighborhood https://dms-cf-08.dimu.org/image/032ykUus1ixX?dimension=1200x1200 https://dms-cf-08.dimu.org/image/032ykUus1ixX?dimension=1200...

- Kirby64 3y agoVery interesting. Seems like that works much better as the power demand per house in the EU is lower, and the higher voltage gives you a bit more leeway. Frankly, I would be concerned about voltage drop for the far houses... even 400V is going to have some pretty beefy voltage drop under load unless the conductors are enormous.
