High Voltage Connectors -SHV, MHV, HN, 10kV and 20kV
SHV Connectors.
SHV Connectors are available for a variety of coaxial cable types including RG58, and RG59. However, you do need to be aware that these cable types themselves are typically rated at 2kV peak voltage, or less, ( it can vary according to source) and that any cable assembly is only as good as its weakest component.

Recommended Cable.
Tests have concluded that RG11 is a good choice for its high dielectric breakdown characteristics and isn’t too heavy for the connector itself. RG11 is a 75 ohm cable but that isn’t significant for HV purposes, except that there tends to be a higher ratio of dielectric insulator to metal, than for 50 ohm cables, which means that their voltage breakdown should be higher. This combination should mean that the total assembly can be specified at the same voltage as the connectors themselves.
