I have a relative with a house in Quillan, (another small French town). His house was rewired completely when he bought it about four years ago and has a fairly substantial, perhaps 60amp, single phase supply from a pole like those. The house next door however appears to have a three phase supply from the same pole and on very thin wires. I honestly thought they were telephone wires at first sight!
There is also a programme of work in hand to bury the cabling underground, in several towns in the area.
