> I'd have thought you'd make the cable have the same net density as water, so it is effectively weightless.

It still has momentum. So it could be broken just by trying to pull it - even without the weight.

And you are right - "pressure conditions" is not correct. It's simply the weight of the cable.

I'd guess even changing its density wouldn't be trivial. Whatever material you choose it'll have to stand the pressure without compacting.
