I've been tasked with putting together a rough estimate for a medium voltage overhead line. All my design experience is from the utility source down, so this foray into the medium voltage world is new to me, and I'm hoping someone here can provide me a little guidance on determining what this installation will look like. Below are my parameters:
I need to span about 800'-1000' total from the source to my building, where we'll be feeding a pad mount transformer.
Overhead line will be 6.9 KV, 3 conductor.
This will be installed on a large industrial site, so the span is pretty much clear (no buildings or homes in the vicinity of the line).
Is there a rule of thumb that can help me roughly determine pole span, pole heights, type of pole, etc.? What about conductor size/type?
