Hi All,

I bought a 6mm SWA cable from CEF and realised the external diameter is 15.1mm however on the website it says the external diameter is 16.6mm? Have I been given an incorrect cable size? They are no markings on the armoured cable to state the size.

I also purchased a 2.5mm SWA cable and the external diameter is 12.9mm and the product spec on the website states 14.1mm.

I wanted to post this just to get some feedback as I will be getting a trench dug up and wouldn't want to rip the cables apart once installed.

Any advice will be appreciated.

Thanks
Kibz.
 
SWA cables with the same size and number of conductors can vary considerably in size, depending on the shape of the individual insulated conductors (not all are round), and how they are packaged, sometimes with filler cords.
Probably a different make from the one on the website.
I've often found that the correct gland for a particular SWA is not any of the ones listed on the packet.
 
It's probably just a different brand or different plastic used. Although staff at my local cef are generally idiots and rarely stay more than a few weeks but I'd like to hope they can read a label with cable size correctly.

I may pop in store to check tomorrow with them as my veneer gauge confirms the sizes as being different
 
Don't forget that it's 6mm square for each conductor (the total cross sectional area of all the strands in each conductor added together), not the diameter of the conductor.

Thanks yes I understand that I actually curbside of the cable and it doesn't look like 6mm in diameter for the line and neutral condictors
 
Swa I use has size and number of cores stamped on external insulation, along with bs number and voltage rating.
3x6, in your case.

What make is the cable?
 
All XLPE.
3 x 6mm Doncaster is 14.9mm o.d
3 x 6mm Eland and Batt are 16.6mm o.d
3x 6mm Cleveland is 15.14 o.d

3 x 10mm is around 19mm

There's nothing close enough in 3 core for it to not be 6mm

Hi ipf,
I have checked this morning and have gone through the cable indents.

I can confirm that the cable is badged as follows:

Basec Electrical Cable 600/1000V, BS 5467 ATOM 3 x 6mm

The writing is so small that you can barely read it.
The best way is to run you r finger tips and feel the indents of the label and you will need a light to flash onto the cable where I saw the number/sizing.

Thanks for the help - The cable size is correct - saves me a trip to CEF.

Cheers
Kibz

Hi K,
Thanks for the tip - I checked this morning to find the cable is a 3 x 6mm2 cable labelled as Basec Electrical Cable 600/1000V BS5467 / Atom 3 X 6mm2
cheers
