For the section power, I suggest the following improvements:
- conductor count and voltages should be freely choseable, as sometimes non-standardized voltages are sometimes used and the conductor count can be at least each number between 1 and 18 ( yes, there are powerlines with only 1 conductor per pylon. HVDC Cahora Bassa is one of them)
- it should be setable the function of a pylon in the line: is it a suspension tower, a strainer, a transposing tower, a branch, etc.
- it should be setable the pylon type, I mean hereby crossbar count and type of conductor arrangement
- sometimes pylons carry circuits with different voltages ( and even frequencies), so it should be choseable the count of different systems and of what kind they are
