That's a good idea to put it in conduit, if there's any worry.
It's certainly a very safe way to do it.

The thing about noise is that the twisting is 95% of the noise rejection,
at RF frequencies- any shielding or 'screening' is good for 5-9 dB, whereas
the twisting is in the 20-25 dB range. Which is REALLY counterintuitive,
but that's what the maths say, and our field experience really agrees with-
balanced twisted pairs very seldom have real RF noise issues, whereas unbalanced
signals are just antennas waiting to happen....
