Better belts, poles and pipes.
You can modify this mod as much as you like.

small electric pole:maximum wire distance = 10,supply area distance = 4
medium electric pole:maximum wire distance = 20,supply area distance = 6
big electric pole:.maximum wire distance = 40,supply area distance = 9
substation:maximum wire distance = 25,supply area distance = 10
pipe to ground:.max underground distance = 200
underground belt:max distance = max distance + 5
