String in SWA cables

[Stroppy]

Here's a question: What is the purpose of the length of string found in the middle of larger CSA SWA cables? Strain relief when pulling the cable, or something else?

Did any one use this type of SWA gland? For interior use only, i loved them - our local wholesaler salesman gave us a couple to try a few years ago and they were so easy to use.

I've just got that picture from google now, so obviouslly some dodgey websites are still selling them - however our wholesaler had said they have become defunct.

No, never seen them before. But i have come across plastic SWA glands recently, that would be very handy for isolating the armouring, in say supplying a TT system from a TNC-S supply. Virtually exactly the same idea as the standard brass gland, in that they lock the armour to the gland body. Only seen them in 20 and 25mm sizes though!! Made in China!! lol!!

I do hope your joking here?? lol!!

No? It works. It doubles up as an earth.

I’ve heard of “string theory”, you’re string earthing theory is a new one on me.

Having had a quick look at one of you’re previous posts, Using generator for Ze reading. I’m of the opinion you’re somewhat tenuous grasp of the principals of earthing and continuity has decidedly slipped.

Superconducting cables!

No more need for any cable calcs!!!!

I've yet to see a conductive or semi conductive filler material used in any multicore LV cable i've ever seen or worked with.

I think it would be a ''new one'' to know, for the cable manufacturers too!! lol!!

You can't honestly expect anyone to take them comments seriouslly can you hoover? Lets just say you're actually telling the truth, what / who told you to do that in the first place? There is noway a piece of filler string is doubling-up as an earth in any cable, in any installation on any planet!

Definitley a wind-up merchant lol! Well played though hoover, you did mak me laugh.

I can literally imagine the assessor's face when he'd be doing the workshop sessions at college haha.

String is a conductor...how do you think it transmits the data when you put 2 empty cans on the end to make a phone line...

Come on guys, simple...

Haha, we wish!

If string was a conductor i'd be straight down the local £1 shop buying a massive ball of it and using it as singles haha

You'd have to buy some felt tips while you where there to colour it in though...identify conductors, dont want to fall foul of the regs...

Easier dyeing it, Brown, Blue & Stripey Green/Yellow, readily available from your local haberdashery shop.

Lol some guys on here need to lighten up. I was flat out on the whiskey over Christmas.

Could you run it in conduit? Wouldn't all those electric thingies leak out?

 

[Sintra]

Oh I will it sure beats a long weight and tartan paint etc. I really can't wait to put this one into practice.

 

[Knobhead]

Hang on, tie little bells to the strings. Run it in conduit to a little tassled thing at the end.

 

[Brightspark2]

Could you run it in conduit?

You could...you just have to pull it through with some cable first...

I will say one thing about the string conductor, I have never had a low IR reading, although R1 can be a bit interesting!:rolleyes2:

With the old wax impregnated jute worming you wouldn't have a problem. Modern stuff it would act like a wick.
