kmt. You will have the same power of transformers per consumed x000kw in Germany as the US, UK or France. The distribution of power from the Generating Plant at perhaps 132,000 volts, for economy of transmission, stepping down to 66,000v - 6600v in the suberbs, and finally to 230v per phase at a local level. The ecomomic transmission distance of 230v is only a few kilometers, so there will be a lot of them near you in Hamburg. Perhaps they are hidden in 'buildings' (or behind them), like here in France where traditionally they built a masonary/concrete enclosure to house the transformers? You must also note that many US pics are in big cities with high power consumptions and that the US seems to have opted for pole-mounted [aka 'Pole Pigs' ] transformers serving a few homes/businesses, rather than ground level [pad mounted] units of larger capacity. Pole mounting, and hence visibility, is now the norm here, so perhaps they are cheaper to install?
