A commercial HF amplifier manufacturer uses silicone insulated cable which
is used in neon lighting applications.
Check this link: http://www.bambachcables.com.au/other.htm and search in
this page for: neon sign lighting discharge high tension cable
The cable is rated for 7.5-15 kV
Besides the HT voltage ratings I guess the current rating is important too.
Silicone insulation might have an advantage in high temperature conditions.
The SHV plugs are rated 10 amps, the plug dielectric 5 kV and working
voltage 3.5 kV rms so you I guess one could use the SHV plugs on a 20 kW
output class AB1 amplifier
