70mm SWA

[zeroberto]

Just connected a 70mm 3 core SWA sub main. I'm in the sticks, no Industrial work here at all so out of the ordinary for us (few farm buildings etc) & our usual swa size is 16 or 25mm. Sheltered life I know!

Anyway just want to tip my hat to you guys who work with this size of cable on a regular basis - what a beast to work with. Nice bit of job satisfaction when we finally got the glands on though.

Again, industrial guys I salute you!, hopefully never see this again for a few years.

cheers

Here's one for you all, if you pull in 4 single SWAs and terminate them. How do you stop eddy currents?

I don't actually know but this thread got me thinking about it.

Yeah, I use these for domestic lighting circuits to account for loft insulation etc.

Seriously, never used anything above the usual boring domestic sizes.

youre soo missing out lol.
anything above 95mm is like bending iron bars :-D
i gland using my teeth
im that hardcore !

You're making me tired just thinking about it! I find 10mm T&E a real chore to route around. Maybe I'm getting lazy in my old age

use a non ferous gland plate or tuffnol or just throw the gland plate away crimp a lug on job done (seen it done)

1000mm aluminium singles, are the biggest I've had to deal with.

240mm 4c swa is the biggest I've glanded , but as others have stated I find it easier to ring and gland than the smaller stuff .

240 4c is the biggest i have done so far as well , but to say it was easier than 1.5 /2.5 stuff is a bit wishful if you ask me ?
It did not seem that way to me !
Having said that , if the small stuff is from CEF i could see what you mean !:devil:

Did a 300mm 4c swa parallel supply last week.

Normally domestic sizes followed by arguments about using the armour for earth. Have farted around with 70mm but today have been ripping out the potato measurement equivalent of 4 core 70mm lead sheathed, old school SWA. God damn it that stuff is heavy, would of loved to see back in the day sparks pulling a few hundred meters of it down a narrow cable tunnel!

Also 90mm ish singles, which had all stuck together where they've got hot and the (bitumen?) had melted

Biggest I have done is 2x 400mm 4 core in parallel. Was good fun. Last July I done 2x 300mm 4 cores in parallel and on the same job 2x 150mm 4 cores in separate runs. Last week it was a 70mm 4 core. I love doing the bigger SWA cable and glands.

Pulled in - 300mm2 4 core armoured

Terminated - 240mm2 4 core

Ripped out - 1000mm2 copper singles

Hardest pull was 16 ton of 240mm2 single core awa through service ducts up 7 floors onto roof, 3 on top floor, 1 on ground floor, 1 on every other floor.

Anyone else waiting on Tonys input on this one? I reckon he's done a few 1000mm's!

Ringing and glanding is the easy bit! It's getting the beast into whatever your connecting it too! Lol!

Any single core cables, will have Aluminium so-called armouring, not steel...

i believe the key phrase may be "non-ferrous" metals.
which have no electromagn. properties.
