From the few handfuls of times that i have made the calculation, it seems to be about 370 ohms. That can't be a coincidence can it?

You should read up before you post, see:
Sure it can. The serious high-power ones around here are certainly higher than 370 ohms, which would have a spacing/wire-diameter ratio of only 11:1 -- that's for a two-wire line in free-space but should be quite close for differential mode of two wires of a three-wire line, well above ground. What I see around here is a spacing/diameter ratio more like 100:1.
If I'm not mistaken, another advantage of a high-voltage DC line is much less corona loss than an AC line. -- Yes, since I was unsure about this, I did a little search and uncovered a paper from ABB at
