HELP sizing SWA___________

[Judd]

For a Job I need to extend and relocate 3x SWA cables, after inspecting the cables I first concluded that they were 25mm 2core, after then comparing an off cut of 25mm 3 core to the existing cables the 3core appears the same size or even possibly smaller, I am now pondering if the existing cables are 35mm 2 core,
I only have the one picture at the moment but will be able to post a picture of inside the enclosures in a couple of days, all cables fit into a standard 60947-3, would 35mm fit into one?
Any help appreciated thanks

Correct me if I'm wrong but aren't cables >25 sector shaped?

It depends when they were made and who made them, Ive seem some old 10mm 2 core with shaped conductors before and some 35mm 4 core with round.

Get a 25mm and 35mm through crimp and see which one fits properly.

too sensible. 10 biscuits docked from pay. .

What F***wit cut the pvc outer sheath to install BS951 clamps. What the hell would have been wrong to crimp a lug onto the earth cable and bolt it on to the banjo with the gland

Because that would be too simple for some people, I would crimp it and use a banjo or locking nut.

I've seen loads of pipe clamps on armoured cables recently. Shoddy.

The only thing that throwing me is why a 2core and a 3core appear the same size, more bedding in older cables?
