Gentlemen, it is "moyenne tension" and voltage can differ localy, from city to city or region to region, this comes for history where theyre where more small distribution companies. You still can find many different voltage ranges over the country up to 20kv Like Felixc correctly indicated.
I believe 1kV is valid trough whole Europe now for LV/MV seperation. Depending countries the MV/HV seperation is not so clear, some switch at 50kV, 70kV some at 36kV .... and so one...
