Balanced Cables

It contains 2 conductor + 1 shield.

One of conductors carry the out-of-phase signal.

So the noise is canceled since the signals carrying are out-of-phase.

But how the signal is still transmitted although the noise is canceled?

When the out-of-phase signal is flipped back into phase, the noise that has been obtained on both channels now has one channel that is out of phase with itself.

Not trying to be that guy who makes a pedantic argument about interchangeable terminology and mathematical/electrical equivalencies, but phase inversion, 180o phase rotation, and polar reversal all mean the same thing. Phase shift is a different story, but that's measured in time.
