[Amps] SHV connectors...

[Steve Thompson]

I think the 1900V rating applies under circumstances which are 
very different from using the cable with SHV connectors.

The breakdown voltage for polyethylene is something around 
20kV/mm. I have tested different brands of RG58 for breakdown - if 
the centre dielectric is long enough so that the open end does not 
arc, I have never seen breakdown at the 16kV limit of my tester.

SHV connectors assembled with RG58 are rated for 5kV+, for 
example, MDC Vacuum in the UK have a version rated for 10kV with 
RG58 specified as the cable to use.
