Do you have any data comparing same cross-section stranded and solid-core impedances vs. freq?
I have to my disposal stranded 16mm2 or solid-core 6mm2 run to the ground. |

At one time I experimented quite a bit with different wire configurations: solid core, stranded, etc. ... even very thin sheets of copper foils for AC wiring. My best results were with 5 mm2 solid core copper hand wound into a triple helix configuration so that the individual wires were always at 90 degrees to each other at all points. This being said, the effects were very subtle and easily overshadowed by variations in construction, insulation, shielding, etc. In my opinion, it is far better to use the easiest wires to work with to minimize any issues with the physical and mechanical construction and installation of the wires. Installation is never ideal, and it is more important to ensure that it can be accomplished in such a way that there is no compromise that may more significantly impact the system.
