Running two power cables in same conduit

[yaserhassan]

Hi
Is it advisable to run 110VAC cable from a generator (clean) with 110VAC from the sub station; one of them for lighting and the other for CCTV; the concern is if the one for lighting is not clean (not consisting of a pure sine wave or carrying interference) would that effect the power line of the CCTV even though both are 110VAC.
the installation is over seas where the power from the station is not consistance.
