Yep it exceed the max line distance.
You can edit the file "data-final-fixes.lua" lines 115 and 116
from:
mult(pole, "maximum_wire_distance", "powerpole_reach", nil, 1)
mult(pole, "supply_area_distance", "powerpole_area", nil, pole.supply_area_distance % 1)
to:
mult(pole, "maximum_wire_distance", "powerpole_reach", nil, 1, 64)
mult(pole, "supply_area_distance", "powerpole_area", nil, pole.supply_area_distance % 1, 64)
It will use the last parameter of that function and enforce a max value of 64 for electric poles.
