Hey D.C.,
    If I understand you correctly you will be
using 160kW at 800V.   That is essentially 200
amps continuous current equivalent.   At
800V,  you should not really need a large radius
of curvature to prevent corona losses.  I'm
looking at copper bus bars and it would appear
you could use something like 1/8 in, by 3 1/2
inch buss bars, which would work for 800 amps rms
for a 30º rise in temp, but for 200 amps, would
probably stay pretty cool.  At the low frequency
you plan to use,  I don't think skin depth would
be a serious issue.  The sections could be bolted
together with enough overlap to minimize
resistance.  Just a thought.  Here's the link I was looking at.
