Heavy duty ethernet cable?

[integerspin]

I was just wondering if there is a heavy duty ethernet cable.
I have cables to run though an artciulating conduit from a
computer to the boards in a milling machine, I will have to
run them in something but something a bit heavier to start
with would be good.

How heavy duty do you want? You could use cat 6 or an external grade cable that has a more robust (but less flexible) outer sheath, or if you want really heavy duty you could get SWA (Steel Wire Armoured) cable.

The original wiring was all rubber sheathed with all pairs individualy shielded.
I have some boxes of the orignal wiring but most of it went in the bin.

Outdood type is probably fine. I was just looking at the belden site, lot's of wire there.
I guess I need to look at somewhere that will sell by the metre.

Not sure where you can get it by the metre (Maybe eBay, but no quality guarantee.

Solid core cables will fatigue and fracture with repeated bending. Stranded core is best in this case.

Depends how much bending is involved - I agree that solid is a poorer choice for patch cables, but in this use case, if it's a fit and forget cable to a bit of kit that is rarely moved, solid would be fine - and external grade cable is only available as a solid core variant (as far as I can tell). The stiffer outer core tends to mitigate against extreme bending anyway.

He seemed to emphasise heavy duty cabling for an articulating conduit, so I imagine that's going to be an issue. But you're right, mechanical durability and external grade is a non-starter. He'll have to go with one or the other, depending on the priority.

Hmm, I just came across this bad-boy, it's stranded, shielded, and armoured:

Probably quite pricey and hard to get a hold of, and corrosion might still be more of an issue, but it could get the job done once-and-for-all™.

Really heavy duty - designed to Dug-in-Ground use or in permanent conduit - great for taking it to an outbuilding where a catenary is ruled out, but for domestic use, I would probably use external grade run in some hosepipe to give a bit of additional protection and buried about 3 feet down (if it was in a garden - with markers showing start and end points)
