I think 213 will take that easily. It was a while ago, but I'm sure that I couldn't detect any leakage on 213 with my tester maxed out at 16kV. A local 'maker' group used it to repair a 35kV lead on a laser cutter. As far as I know it's working ok.

Good quality RG58 should take 8kV without any problems - again, I've had it at the limit of my tester. I suspect the cable working voltage specs are often derived from connector limitations.


Does anybody know how much max V is on RG-213 ? Like what are the results if a hi-pot tester used.. and say cranked up to the point where just a few microamps occurs . I have an application where I need a HV cable, less than 10 ft, that will easily handle 5700 / 7700 vdc. It will be hardwired at both ends, no HV connectors. And with braid peeled way back from the center conductor, like 2-4 inches . The plan was to also wrap some red electrical tape every few inches along its entire length, to readily identify it as a HV cable.
