[Amps] RG-213 Hi pot ?

[Steve Thompson]

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.
