SWA Jointing

londonlec · Feb 18, 2014

Hi All,

I have an SWA resin joint to do, although the two cables are different sizes (35 and 50mm), the cables are existing and buried under tarmac.

Is there a torpedo kit which will let me terminate two different size cores?

I know the DNO near me tighten a bolt down onto the core using a socket, something like that would be ideal.

Many thanks.

Didn’t say I don’t trust mechanical connections, I’ve just never used them, I’ve seen DNO jointers using them.
OK I’m a dinosaur.
With compound joints crimps are a No No. Compound is constantly on the move and will creep in to a crimped connection, degrading it.
I did my jointing training with EMEB, they were adamant crimps shouldn’t be used. The last 11KV termination I did the manager insisted I used crimped lugs. OK I did, while his back was turned I ran solder in to them. Now with resin joints that problem is a thing of the past, once set it doesn’t move.

Out of interest, anyone tried to break a resin joint? I put one on the anvil and gave it a tap with a sledge hammer. The hammer bounced off. Pity they didn’t comply with M&Q.

No way you could get away with doing any hot joints on a site these days!, crimped or mechanical only, it's grief enough sneaking a grinder on site! ( I cut all me containment with one!) crimped joints are spot on but if I had to joint two different sizes it would always be mechanical with snap off bolts. They are also standard issue to the DNO so I trust em!

and you did rite Aiden...
