[graham123]

when I was an apprentice I had to help someone do some swa cable joints, it rained.

The last time I done a cable joint it snowed, its sods law, like Tony said!!

Worst one i ever did was a 150mm that was chopped in half with a digger absoltute friggin pig up to my knees in mud cold , wet hydrolic crimpers , nice thing was the apprentice mixed what looked like a gallon of resin

I’d have given him a clip around the ear. Gallon of tea first, then the compound.

That was one beauty of the old hot fill compound joints, first thing to get packed in my old tool chest was the frying pan and kettle. If you were doing a couple of 11KV through joints it was like going camping for a couple of days and getting paid for it. I never worked out how the foreman worked it. Just as the bacon’s going in the pan he’d appear on the horizon. Doing one joint the local farmer showed up with a tray of eggs for up. Happy days

The one I just did the resin went off pretty quick, couldn't get it all to spread in the joint.

3M


Have alook at this 11

QUIZ Question what does "3M" stand for ???

 

[mogga]

As tony says make sure its Level also SEALED well its worth a roll of tape (if its a big joint) Keep it DRY make sure your tested before filling leave to set for a good while ( go n have a roll n cuppa) Iv also seen this new "raychem" gel stuff but not used it yet seems more for joint boxes like 4x4s n makes completly watertight

You’re not the only one. I spent to long mixing the resin it was going off as I pored it. So now I’ve got a half full joint. What the hell do I do now. Quick trip to the workshop and I found an old kit, got back to site to find the foreman in the trench looking at the joint so I had to come clean and tell him what had gone on. I mixed the second lot and pored that in, by this time the foreman is howling with laughter, the first batch was black, this lot was cream. The joint looked like a demented Everton mint! Get it bloody buried, quick!

Minnesota Mining and Manufacturing Company They don't seem to put it on any of their literature now

I remember when i was an apprentice and we had to join an SWA with a resin kit. When we opened the box of the kit there was connector blocks in, im sure, according to instructions to join the cable!! Needless to say these werent used but who the hell puts these kits together???

A lot of kits come with connector blocks.

 

[johnboy6083]

I always ditch the chocks and use crimps. That said, if you use the connector blocks properly, IR both conductors cut to the full length of the connector block, and secured under both screws, then there shouldn't be a problem. It ain't gona work loose, surrounded by resin!

Lots of good advice here, I've done lots of these (our ground works team can be pretty gung ho ... 'Well us saw the warning tape, but us thought we'd carry on digging boy...')

I always try & get my hands on the joint kit before buying it, various manufacturers some are beter than others.

Take your time with the prep work, make sure you've got a big enough hole/working area to get your joint flat & level & do all your checks/tests before you even mix your resin.

You ought to leave the joint 12/24 hours to go off before backfilling but most manufacturers say you can energise them straight away.

Hope this helps
