Picture of the week!™

Well folks, it's that time again!

I was installing some 2 core 1.0mm² flex this week, and noticed a bumpy bit on it.

Here is what I found:

Not more import cable from china or eastern europe is it RF?

 

[RF Lighting]

It is stamped "TO BS 6500"

The brand would lead you to beleive it is manufactured in South Yorkshire.

common practice, and not the first splice we've had posted on here..

it's the way they make the cable..so that there is a continuous feed through the extruder / dip / however they apply the outer sheath..

they generally mark and cut out the jointed bit but sometimes it escapes....

oit pays to be vigilant as well because the other cores will be spliced somewhere nearby also..

A freind who does a lot of PAT testing saw one in a peice of factory fitted flex!

Makes you wonder how often they slip through the net, surely a couple of lasers scanning the cable as it get spooled onto the final reels would pick that up?

Anyone ever seen it in T&E?

Not good at all when stuff like that slips through!! Fire waiting to happen.

Yes, I've seen it on Twin & Earth. The cores that time were not 'insulated' by tape. The problem would have been found by Inspection & Test if it was not for the beagle eye of an apprentice at the time!

 

[ColJack]

there's probably better conduction through that joint than in the straight length of cable itself..

anyone care to do the experiment?

South Yorkshire?

Not a company owned by a large wholesaler unliked by many here?

Nice to see that it's not just phone cables that get that sort of quality control !! I've come across quite a few of the underground 50pr and 100pr types where I've cut into a solid cable, only to be confronted by that sort of joint.

At least with phone cable you're only looking at a maximum of about 120v across the pair.

isn't a dacs line 140V?

No Plugwash, it's 120v. At least that's what it says on the DACS unit on the pole/in the Joint Box & that's the voltage we get when testing lines.
Sorry for not replying earlier but I didn't subscribe to this thread and I've only just noticed your reply.
