SWA Diameters

[New2Game]

What is the cable diameter of 16mm^2 3core SWA and diameter of 10mm^2 3core SWA?

I've seen the dimensions on a spec sheet years ago.Look on cable manufacturers websites they may have them on there

Nominal O.D for 10mm^2 3 core SWA - 18.9mm
Nominal O.D for 16mm^2 3 core SWA - 23.1mm

Has SWA got thinner over the last 10 years or so? I'm sure 16.0mm² SWA used to be thicker when I first started, or have I just got used to working with big SWA?

XLPE is generally thinner in diameter than pvc/pvc isn't it?

Whats the diff between normal SWA and XLPE SWA? Apart from higher current ratings. Can XLPE be used instead of SWA just for higher current capacity for size? Are diff glands etc?

You have to ensure that what you are terminating the XLPE to can withstand the higher operating temp (90c) otherwise you must use pvc/pvc ratings.

So if XLPE was drawing its max rated current it would operate at 90 degrees?

In theory yes
