You can be sure that if the supply says NEGATIVE polarity that the torid is the output hot (negative) and that ground or chassis is positive.

There is NO cabling for these! You are to arrange for your own takeoff as these levels! They figure if you buy at this level, you have the skills needed to connect to your app. without their help.

Some multiplier type power supplies, DO have a bipolar output, that ie + and - HV, they will have a high voltage termination like the one on the Gamma supply, for EACH polarity.

I know of at least one xray HV supply which has a bipolar drive...which minimizes the insulation issues since an xray tube can have a cathode at negative hv and the target at positive hv.

But as have already been said, each hv output must have appropriate terminals for the rated voltage.

Taking another look at this simple system one sees no place for a 200kv plug of any sort. It is obvious the toriod is the output, plus or minus, you will have to touch it to get your juice. Any plug type connector terminal block to a cable that will handle 200kv will be sunk in a lot of oil. The toroid allows for simple air connection via smooth often chromed piping. A huge percentage of such systems are AIR connects as they are cheap and small.
