wind farm collection system
(OP)
What would be the advantage to installing a 34.5kv collection system where the cables are kept seperated by a minimum of seven inches horizontally vs. zip tied together every 4 feet, or does it matter? This is at a wind farm. I have seen them done both ways. Of course the engineers who designed them aren't available for questioning. It seems that there shouldn't be a need for cross cancellation due to the generator producing a balanced load. I have heard that you can follow the buried circuit over snowy areas where they are zip tied as they heat the ground, I haven't been back to see it though.

Consitering the installers point of view, it's just easer to zip tie the cables and not worry about transpositions.
