Discuss Pulling 16mm SWA through 150 M of conduit? in the UK Electrical Forum area at ElectriciansForums.net
Since the cable will be down there in 100% humidity anyhow, maybe not a practical problem...
OK, since water's been mentioned, if the ducting is lying at low level or the ends are upturned and not capped, there's a fair chance of some water in the duct. This leads me to ask whether anyone's tried deliberately filing a duct with water before pulling a cable through. It would provide some lubrication (although not as good as a proper lubricant) and, maybe more importantly, it would reduce the effective weight of the cable. Any thoughts?
If a couple of labours can get enough purchase on a bit of rope to stretch that piece of armoured I will eat my hat !!! I am not talking about yanking the hell out of it , and assume a modicum of sense is being applied to the pull and the cable is correctly secured , having said that .
I'm in Surrey too, on the basis that you try and pull the SWA through can I come and watch?
Unroll 150m of 16mm 3 core on a carpark, get hold of one end and pull like hell, feel the give and back lash in the cable, that's with only one person try then a couple. It's easily possible to destroy the cable in this situation.
Me too
Looks like we might have a (cable) pulling party? :smile5:
that sounds like p0rnography...Looks like we might have a (cable) pulling party? :smile5:

I can imagine you having friction trouble dragging it round that bend.

I still think filling the ducting with water was the best idea :rolleyes4::confused5:.
Hopefully the sheath isn't damaged mind
Now come on, are you actually being serious?? lol!!
hahahahaha....................read the last line again:frown2:
You're laughing but i'm pretty sure some daft bugger will remember your post and fill a duct with water!! lol!!
Let's hope the water isn't on a meter, and has devised some sort of method of draining it all out. ...lol!!

Me and my old boss tried something similar years ago. Same ducting and cable size. Duct about 80metres long with a slight dogleg at one end. We had to tie the rope to the back of my van as pulling it by hand was impossible. Managed to get it 80% of the way but the rope snapped when the SWA reached the dogleg. we dug a hole found the break and managed to finish the job but to be honest I'd never wanna do it again.
Just let the customer be aware that it might not be possible.
E54 ain't gonna be pleased with your van antics :lol: Daz

I expect not! Fortunately for me, I care very little for his archaic opinions.
"Never again". - That's a recurring theme! I was just talking to the hire company about their winch, and they don't really know how to use it. For instance 10mm polypropylene (~ 1 tonne break, but very stretchy, maybe need to go bigger) or spend an arm and a leg on dyneema rope (winch manufacturers say use non-stretch rope).
While I don't know much about pulling very long cables (and I'm going to be very wary if anyone ever asks me to now), why does it matter if the rope is stretchy? Could it be good to have some stretch in it, to reduce the mechanical shocks to the cable? Perhaps E54 or someone can advise.
