Is that a low wattage 220Vac => 1.5Vac transformer?

You can get HV out, no prob, up to the point where the insulation
fails. You'll see when that happens ;-)

Theoretically, moving from 1.5V input at 50Hz to your 18V input the freq
should be 50*(18/1.5) = 600Hz. Otherwise you run the risk of burning it up.

You estimated micro-amps (=short circuit current?) as the xfmr output,
which is a relatively safe level already. Less than that is even safer.

If you want to charge a typical TC tank capacitor: it works, but it will
take ages to get it charged if the xfmr can supply only a few microamps.
That's just a thing to remember...
