SWA/SY cable in a fibre duct

[steve2023]

OK. I can already feel the eyes rolling

I am working in a yard where we are having trouble with vandalism.
There is absolutely no way of getting a cable (easily) down the to front gate, as the perimeter is hedging and the car park is concreted entirely.

The ONLY duct to the gate from the building houses a pair of Fibre optic broadband cables. I think it's a flexible 50mm duct and it has a draw rope.

This is a no no I realise. but kinda out of ideas. Cutting up the car park isn't going to happen.

I could in theory, just run an external cat6e down there and put up a POE camera. But ideally we want to put up a couple LED floods.

The mains I don't believe will interfere with the fibre, but I am sure this will be massively frowned upon.

Shall I get my coat?

edit...

The other option is to go the long way around, but that would mean some kind of trunking mounted to a fence like the one below.
Not an easy install, and the fence 'could' be damaged by reversing cars, so I imagine it will need mechanical protection from that possible event.
Can you install Galv trunking outside successfully?

Reason for trunking is there is talk of future car chargers, so the ability to run multiple cables out would be helpful.

I wouldn’t use the duct you may damage the fibre

Can you not dig in a duct along the fence . I wouldn't want to run trunking outside. You can run tray outside but if they are having problems with vandalism. This could be damaged

No. The concrete has been run almost right up to a pretty well established hedge. Digging it would be a nightmare.
Trunking outside seems a bit rubbish. Yes, tray would look far better, but like you say.... vandals etc

I think at this point, I may run tray.
It's only about 60m. I reckon if I throw in a 3 core 6mm SWA to the bottom of an existing lamppost (that is entirely dead - cut off years ago), then I am covered. Only planning to run a couple of 300w LED floods.
6mm should give me leeway for any later additions.

If you run tray I would fit another run of tray over the top to help prevent vandals cutting the cables. Also make sure the tray ratted to be used outside

Is tray available that isn't suitable for outdoor use?

If you run tray I would fit another run of tray over the top to help prevent vandals cutting the cables.

Or you could just fit cable tray lids.

Also make sure the tray ratted to be used outside

Is there any tray that can't be used outside?

Had to google this. Something new learnt today.

yes you want to use hot diped if used out side .

Or you could just fit cable tray lids.


Is there any tray that can't be used

Thanks dave did not realise you could get tray lid

Yes. Hot dipped tray is what you want. It doesn’t look as neat as the other tray but its got a proper protective coating on it. Spray any cuts with plenty of galvanised spray too. Personally i would to to an iron mungers for the paint as the stuff from cites etc can be pretty naff.
