That's typically Italian. All other countries I know of have either proper US style OH services with a riser or underground service with a meter inside the house. Only the Italian run Quadruplex OH on their facades.
It's 230/400V 3ph, you can see the 3 phases and the neutral bundled together. This is an extraordinarily bad one though, the ones I saw in ROme and some small villages were muchg neater, though still just plain Quadruplex clipped to the facades. Same with street lighting and phone lines.
Austrian underground services usually have a concrete housing, about 5' high with the PoCo fuses and the N/Ground bond at the road if the house is set back or the disconnect enclosure is sunk into the facade, sometimes also in the hallway, directly next to the front door (only apartment buildings).
