Correct termination of SWA cable

[Midwest]

Having been reading a thread recently about private lamp post installations, I've been look at my place of work's lamp posts.

We are considering making some alterations to the existing installation, so I went looking for some manufacturers product details. I took off a post cover, and discovered the detail plate, but also noted the swa cables in & out, haven't been terminated with the proper swa glands, but jubilee clips, no shrouds either.

Just to make sure it wasn't a one off, I randomly inspected other posts and found the same. The posts cut outs are these.

I'm not sure how you would terminate swa cables into such a cut out, but I don't think a jubilee clip is a British or Harmonised Standard for use with swa cable. I've only just web searched the cut out, and will make contact with the manufacturer, but what do you guys think?

Needs to be terminated using glands and terminated into the appropriate enclosure

No that is it, shove in cable and use jubbly clip on the armour.

Manufacturers instructions, the brass gland and jubilee clip are provided specifically for SWA terminations. I came across the same thing in the last place I worked and that was the answer in the end.

you jest of course?

 

[Rockingit]

Sure it's not SWA and actually split / con?

 

[westward10]

No that is the purpose of the bottom plate.

 

[Lucien Nunes]

Because it's only designed to be used within the confines of a lighting column, it doesn't need to provide environmental sealing or full mechanical support like a CW gland. The worm drive clips are only to make a termination to the armour which they do better in a tight space with limited access than making a half-cocked job with a gland and pipe grips.

Ok, seems I better go tell my boss the good news. Never thought jubilee clips are deemed a suitable means of termination.

However, I’d of thought a shroud would of been added?

Seen hundreds of those with Jubilee clips in Supermarket car park columns and beacons and bollards.

No, nor me Mate.

If you think about it, it's no different from the spring coils that you get inside a torpedo

 

[westward10]

Don't really see what the benefit of a shroud would be.

Perhaps not. Just always used shrouds everywhere before, guess inside a lamppost with tool access wouldn’t matter.

Learn something every day. Having seen earth clamps used in similar circumstances, surprised to learn jubilee clips as a suitable manufactured method.

Obviously jubilee clips are inappropriate for terminating SWA in most situations, as the cable will be compressed as you tighten up the jubilee clip. However in this case, the armour is placed between the solid gland body and the jubilee clip, and so tightening up the jubilee clip does not compress the cable.

Agree but they CPS that cannot be overtightened, unlike the screw type jubilee clip.

 

[sarky spark]

Ive never seen anything other that this type in any lighting column or street furniture. Ive fitted loads of them myself.

 

[DPG]

I'm waiting for someone to point out that Jubilee clips are actually a specific manufacturer's product, much like Hoover,etc.

Obviously I'm not that pedantic, so it won't be me

 

[wheeto]

The difference, presumably, compared with the torpedo is that they're held in place by spring tension, rather than a screw (or worm drive)
