I want to run a three core power cable in a tight duct with a tv coaxial cable.
Opinions??

Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

SY control cable to help with the interference?

If you are not worried by breaking the rules then I think there is little chance of interference from the mains cable to the coax (presumably bearing digital modulation) I would suggest a continuous foil screened coax cable such as CT100.Lurker":7vzft4ka said:
If you are going to be running high power inverters (to run 3phase motors from single phase power) from the mains cable then I would fit a filter at the inverter end as a precaution.

@Trevanion. I did wonder about that but depends on the power rating of the cable, SWA is also a possiblity but horrible to install in a closed tight duct.

Thanks
The co axial is continuous foil.
The power cable will be just a spur direct from the consumer unit to a wall socket for the tv.
The duct is a slight exaggeration . I plan to run these cables down the corner of a room inside that plastic duct stuff, but wanted to use the smallest I could get away with.
The tv is wall mounted so the run will be about a meter.

Wiring regulations require at least 50mm separation between low voltage (i.e. 230v mains) and extra low voltage (i.e. less than that). This isn't because of interference, but rather that people don't generally turn off the power to the house or use insulated tools when working on telecoms cables.
If this is a minor alteration to existing circuits and doesn't need a building regs certificate, then you get to do your own risk assessment. Of course, per Part P, even that should be tested and certified as complying with BS7671, but only has to be done by a skilled person rather than a paid-up professional.
Practically speaking, there shouldn't be any interference issues; the point of coax cable is that the outer conductor shields the inner one. The regulations issue is up to you.
