I need suggestions for a small wiring job. I'm running 50kV from a VanDeGraff generator to a resistor and a spark gap. I don't want to take too much of a hit from corona losses, but I don't want to get too exotic. The spark gap end needs to be removable, and I'll probably blue tape the other end to the VDG sphere. I don't know what sort of commonly available wire might be suitable. Spark plug wire? 50 is a bit hot really for spark plug systems, the plug gap is much smaller than that at least in cars. 50 will jump over an inch between small spheres. The total length is less than three feet.
