Looks can be deceiving, ask my wife! ;-)
They are specified for 10kV iirc. The construction is very smart, sort of vertical build.
Each pin is individually sheated in a sort of tower.
The internal creeping distances are at least 12mm.
Because of the construction, you should not power them up unless they are plugged into each other.
Redel is a division of Lemo. They cost about 50 euri each. I'll see if I can find the spec sheet.
Found it, attached.

There is no 5 kV there, but a maximum of 3 kV, this is a high-frequency driver where a step-up transformer with a coefficient of 1-100 is installed.
But just in case, I measured the distance between the pins of this connector with a caliper, it is 5 mm, so there has never been and will not be a breakdown at the highest volume.
But in the low-frequency driver there is, yes, the distance between the contacts is 30 mm, there is a 1-200 transformer there.
But this is not the main thing, it is important how all the electrical parts are distributed inside the driver, breakdowns can also unexpectedly occur there. For example, I connected the voltage multiplier itself by surface mounting, twisting and soldering wires from diodes, capacitors and resistors, not trusting the tracks of the PCBs. By the way, it is in these places that dust is attracted, forming dust tracks that partially pass high voltage depending on the humidity of the surrounding air. Therefore, I carefully wrapped the multipliers themselves in cellophane bags and put them in boxes, as my grandmother once did with money (a good habit).

I meant havun's connectors of post #39. The photograph is vague, but it looks like alligator clips on the bottom left. Connecting a 3 kV or more direct-drive amplifier with alligator clips seems rather dangerous.

I see. Because of the context of this thread, I assumed you were connecting a direct-drive amplifier with kilovolts of output voltage and enough current to cause cardiac arrest using thin wires and alligator clips
