HELP sizing SWA___________

Judd · Oct 3, 2018

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

Would look better if everything was lined up neatly. Sorry, not the feedback you were wanting, but I had to say it!

The Ghost · Oct 3, 2018

It look like it could be either but the only way I know to be sure is to get the micrometer out and do the sums to be sure which is what I would do. The BS951 clamps are going I presume? and the swa properly glanded? Single insulated tails are not good either bit of a poor install all in all looks like you have your work cut out.

Judd · Oct 3, 2018

They are all double insulated they just have red and black sheaths. Yes everything is getting re-done, A new hut is being built about 15 metres away to house the 3 existing supplies and a new 4th supply,

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

buzzlightyear · Oct 3, 2018

why you are there, try and take a better picture of the snail on the rotatory switch.

Are they SWA, or split con?

Oh yes, a proper install that...

buzzlightyear · Oct 3, 2018

the only thing is missing is George Formby banjos on that SWA.

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

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.

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?

As I said, extend 3 cables, and supply a new cable to a new build.

for that .

simpson93 · Oct 3, 2018

As above if you asking about volt drop, how far etc.

Just out of interest, will there be another phase supplied or are you planning on splitting one of the existing?
