Those are cables for underground power transmission. They need an awful 
lot of insulation I bet. So overhead lines are likely to be a good deal 
thinner. The German Wikipedia mentions a typical cross-section of 60 
mm^2 of steel surrounded by 257 mm^2 of aluminum, so the diameter should 
be close to 20 mm.
