Default Braiding electrical wiring

Does this affect the electrical properties?

My opinion:
Look up the power transmission characteristics of your proposed wire.
Wire has a certain ohms per unit length per cross sectional area and
per metal composition of the wire. Increasing the length means
power loss. Thinning the wire means power loss.
If I were to thin the wire then I would double the number of strands.
i.e.: run a pair of 20 gauge stranded vs. a single 16 gauge stranded
for the same power requirements. Or you could use thin pure silver wire.

DC can safely be run parallel. No need to X cross the wire.
But if the power is pulsed or has an AC component then braiding
in an X (90 degree) fashion would lower the cross talk but it will
lengthen the wire. (Right-Hand Rule.)
Short runs of parallel are usually ok.
