True, although the superconducting effect is lost under high electric fields.
A superconducor rejects magnetic fields (a bit like a Faraday cage). What if you cranck it up high enough and force the superconductor in place? You lose superconductivity.
For that reason, there is actually a limit to thew current that can be transmitted, though it is much higher than with conventional cables (you still can't power a city with a hair-thin cable, IIRC).
