I take it you've rejected the 1800s aprpoach of bare iron wire on
ceramic standoffs, surface mounted to allow the heat to dissipate.


Thinking about it a lot of 1800s installations would have been private
ones with accumulators for when the steam/gas engine driven dynamo
was shut down. The voltages of some would be not be too different from
ELV systems now and in some respects we have gone full circle with
those wire and cable systems with bare conductors suspended across
counters,window displays etc not being that dissimilar to the 1800s
approach.
