Size Guide for imperial aluminium SWA

[michaelg5]

Evening everyone. Been a long time lurker on the forums but I need some help & guidance.

I am about to do some work on a large industrial premises which the client wants to re-use the existing sub mains. After many discussions about replacing them they have decided to retain them. My issue is that some need to be pulled back and re-terminated but I have been unable to confirm the size of them. Is there a way (like with metric cables) to determine this (Roughly) from the overall diameter of the cable?

The cables in question are all 4 core Aluminium SWA cables (The only markings on them are Pirelli/General Electric 600/1100v.)

I have 2 diameters, one is 72mm the other is 60mm (In hindsight maybe I should of measured them in inches!!)

It wasn't until after using a manufacturers data for the current metric equivalent that I thought they will probably be imperial and without the correct size will cause me a problem when it comes to the glanding.

Any help or advice would be much appreciated.

Michael

Hi Pete. Unfortunatley not although might have a route around on site, you never know the last tenants might have left them lying about somewhere (Just not it in the switch room!!!!)

It's a pain when you don't have any past references to go by, good luck in your hunt, sorry I can't help you any, not worked with much SWA Ally

What year was the original installation done?

Hi Snowhead. Not sure tbh. I am guessing late 60s early 70s.
