Reply to comment by BackItUpWithLinks in How is storm response and two year tree trimming cheaper than burying electric lines?? by schillerstone

Not only for the labor to do it, but it's my understanding that you need to push more electricity through buried cables as they don't carry as far.

I’m not an expert but that just doesn’t sound right. Assuming the cables they use above ground would be the same as the ones for buried lines, and why wouldn’t they be, the cables will “carry” just as far

They are very much different. the cables on poles wouldn't last a year in the ground, cold, moisture, corrosion (like 8 types of it)

Those pipes will never bee leak proof so conduits with water in them is common and expected.

​

SO i see a dieefernt current/voltage/amperage would be needed and the runs can't be overly long.

I'm not an expert either, but this Wikipedia article touches on the point of how underground cable length is affected by... stuff.

My background is in software development and sales. Electricity is pretty much magic to me.

I looked into it a little more and it appears you’re right. I’m a physics major graduating in May and I would say despite taking 2 semesters of electricity and magnetism, electricity is also magic to me.
