Cable jointing at a cannabis farm - Part 2
VloĆŸit
- Äas pĆidĂĄn 19. 03. 2021
- In this one we've been tasked with cable jointing a existing 240mm SWA onto a new 185mm SWA following some diversions made that fed a cannabis farm. Hopefully this video can give an insight into a day in the life of an industrial electrician.

When the boss asks if you're busy and you can answer, "Yes. Just finishing a joint at the cannabis farm".
You say it may look junky to use the insulation as an extra shield... bah... it's a great use of an otherwise waste product that makes the connection safer! I love your constant attention to safety and detail! Bloody brilliant! Thanks for sharing!
Also the application of vibration to the joint when applying the epoxy will help all air pockets escape making the joint more solid.
We do it so much that we don't throw them away and keep with us.
Kudos guys, a hard days work in the mud. I did many of these 240mm joints about 40 years ago, nothing much seems to have changed, it's still a gym workout. We had a foot pump operated hydraulic cutter and crimper which made life a bit easier, I would imagine battery operated equivalents are available now. Something we learned quickly when pulling in the cables was to be mindful of how the cores rotated, if a cable was layed back to front, the core rotation would be opposite, making it extremely difficult to fit the jointed cable inside the plastic casing, because the last of the four cores would not align neatly, making it a larger joint.
good tip, thanks
Yes sir, i will keep it in mind next time.
The education you provide in your work cannot be thanked enough thank you
Great video mate Ian seems like a right character would be good to see him in future videos
I always wonder if wrapping it with too much tape prevents the resin getting in fully? Definitely use a fair bit but wonder if it would actually seep in better between the cores?
One of my fondest work memories is jointing a telemetry cable between 2 reservoirs summer of '91 (very hot). They put a new water main down the side of an existing mains and hit the cable multiple times.
Apart from the fact I was working with multi- core 1.5mm in blazing hot sunshine this did bring back happy memories.
Brings back memories to a couple of years ago when I had to T joint 185mm armoured cable nice job
I cable splice(joint) in Washington d.c. I work with lead, heat shrinks, and cold shrinks. Much love from across the pawn. How you guys do it is a bit alien to me. Still great work.
This is the content I'm here for đ»
mixed so many of those resin bags over the years jointing multicore traffic signal swa cables ,brings back (bad) memories. Great vid
Who for? Same industry as me :)
@@NoobCannon1234 Dynniq
Hell of a job guys. Mad props from the USA!
Brilliant video. Never seen this done before. I've done similar repairs on catenary cables but they were only 25 mm. Never seen the big stuff
Get a plastic faced hammer for tapping the ally connectors onto the conductors, too much with a metal hammer burrs the ally edges and you canât slide the shear off bit in after..... donât ask me how I know this đ
Also have a word with who orders the gear in, go at least one size up on the resin joint. Better to be plugging the ends of the case up to hold the resin in than fighting the cores together to make it all fit. JME from the few Iâve done.
isnt the purpose of that resin to sweep between the cores what the electrical tape prevents in your case? another is a watertight seal but its insulating in the same time
Mate how many times I walked past those joint boxes in the ground and wanted to see the process. Thank you.
That looked like it went alright tbf đ This takes me back, i did a huge joint for a motorway services yearâs ago. I canât remember the cable size but 25 years on i still have the nightmares đ
Would like to have seen that 'non legitimate' joint cut open to see the standard of work on that .
Probably the same grassy substance but mixed with invisible other chemicals. Oh, you meant the other kind of non-legitimate joint
Home made insulator for the splice. Love it!
Another top quality video mate
GREAT BIT OF ENTERTAINMENT... Not the cannabis farm or Resin I was looking forward to watching.
Thank you regardless! đ
Amazing job guys!!!
I did wonder when you were pulling the cable in whether you had checked the cable rotation so the cores lined up at the joint . The panel end can be crossed over to suit
Is there a way to check the amount of current going through the cable above ground? (while itâs still buried) can I check current using cat v scan or will that only tell me if itâs live or not? do you need to come into contact with the cable insulation to get a current reading ? Or do I need to expose the cores and do high voltage multimeter test lol to get a reading ?
Yes Mikey đ
Great video buddy you rapidly became my favourite channel, I bloody hate domestic with a passion. Keep up the good work mateđ.
Really good info. Thanks
Joints! Cannabis farm! Got my like before I watched the video.
I love jointing at cannabis farms as well...
More or less the same over here in the States. Not very much direct burial cable where we are though. You guys need a dewalt porta-band!
I never realised how much work was involved in installing and jointing those big cores. The last joint I saw in 5he ground had a sort of light brown filling compound this was in my street there is a section of cable thats more joint than cable!
Nice one thanks for the content
Is wrapping with insulation tapes permitted by the manufacturers instructions, and if it is how can you be sure not to create voids in the resin?
Always cool to watch your stuff. Be careful of cutting pvc with a grinder or any hot source, the smoke is incredibly toxic.
What do you do with your leftover cable pieces , do throw them or keep them to sell them in mass? I mean copper isn't cheap here, you can get around $ 8 to 10 per kilo here.
Had to have one of these done on a job i was working on didn't get to see it being done just saw the finished job, so nice to see how its done :)
Enjoy your joint!
Connections are everything in life I feel .
Definitely need to get bigger shells mate. As a DNO jointer myself I do this sort of stuff on a daily basis, usually live. Our shells for that size cable are about 3 times the size, much easier and allows space around the cores and connectors for the resin to run. Good video otherwise đđ»
Canât help with where to get the kit from sorry, all my stuff comes from our own stores. We use kit from TE connectivity, raychem, and lovink. The low voltage connectors we use are basically the same as the ones you used but come with an insulating shroud that clips around it.
Do it live hey??so have you picked out a nice coffin?I think ya talking shit just quietly
Would agree as a DNO joint who does these joints live a bigger shell would definitely be better as you could have more room between cores for resin to get in. Also if you abraded the outer of the cable where it enters the shell the resin would bond better to stop water tracking in. I would always clean and degrease the joint before resin goes in again so it bonds properly. These are the main causes of most of are faults on new joints. You can also work out rotation of the cable so that when you install your new piece you don't get a cross. The more you do the easier it gets
@@danielelise7348 DNOâs have to do majority of LV mains and service live so you donât lose supply to all the other customers on the feeder. Trained to do it live using correct PPE.
@@residualelectricalitâs worth giving UKPowerNetworks a shout mate as the joint packs they use are always best industry standard
Hi is it not better to have NO insulation tape on inside so the resin can get into all the gaps and crevices. Genuine question not having a go. Great vid tho had to do that a couple of times but only on column lighting cable never that size cores. đđ
Nice job .. it's really a pain fighting with 240-185 mmÂČ copper .. surely is a 2 man job . 300mmÂČ alumimium is less weight but still a tough 2 man job connecting them .. they don't stay bended ..
doing a joint at a cannabis farm, wasn't what I was expecting at all, lol
Spent a good chunk of my apprenticeship doing UG joints on 240 mm XLPE armoured netural screen aluminium cable. Can't say I miss being knee deep in water & trying to get a good joint. Great job lads. We occasionally did live taps as well, that was fun. Still have the HV tools in the shed somewhere :-)
My dad was a cable Jointer. Id love to do this at cannabis farms
Great content !
that is one neat job! hard work in the mud and cold... brrrrr Wondering why you need the tape; wouldn't is be enough or better just to have the resin? thanks for your video's, good rendering of the real life of an industrial spark!
Where did you get the orange lay flat tool bag. Thanks for the video.
Love watching all your videos đđ They should make a big wago connector and box for this đđđ
Is the orange bag on loadout shop mate , think it will be quality when working in a garden etc
I was thinking, "so how do you ensure those joins don't touch one another? surely that should be filled with something insulating" turns out I need to wait until I finish the video before thinking lol.
How comes you tested it after, what if there was a fault would you have had to cut through the joining ?
you eating the forbidden corner shop sandwichesđđ
What is the joint called where I branch off of the existing armoured cable? to connect it to a new build off of the existing armoured cable like a T joint or 3 way joint is it the same straight joint but using different (3 way) terminal connectors for another cable?
Great video mate, really interesting. Considering i only do house bashing haha
Ah good old cable jointing, I remember all the early mornings blood, sweat and tears from installing site temporaries Iâm sitting in my company car with my latte thinking thank fuck I donât have to do that anymore.
Must be a an absolute unit of an operation if they need a 4x240mm2. We had 5x240/76mm2 at the machine shop i used to work at, with 16 machines at no less than 16kVA we didn't even utilise 30 percent of the rated capacity with all machines at full blast.
Another Great video. It would be interesting to see all of the equipment you use to create this sort of content, from GoPro body mounts to editing software etc. There doesn't seem to be any commercial catering engineers on CZcams yet, perhaps I should be the first haha
Whats the instructions for these shear offs? Everyone I have used always point out clearly to never use rattlegun to torque them always hand tighten. Apparently it has something to do with the rattlegun shearing it off too early and leeding to a loose connection.
Nice video palđ makes me miss being on the tools.
Easy to criticise somebody elses work, but id always do a quick dead test before the resin pour
Nice little insulation resistantance test :)
Love your work Mike, from aus :)
I enjoyed that
So how was this illegal connection discovered? Did the paint shop owner notice the increased electric bill or was it after the farm got busted by the Po-Po?
I really donât get why manufacturers make the shells for these joints so small. For the sake of a bit extra plastic and resin it would make the job so much easier. Also if youâre doing a lot of work on this size cable Iâd definitely recommend getting a set of ratchet cable cutters. Theyâll change your life! Just donât use them on steel wire. Thatâs an expensive mistake I made...
Best ones are Birkett resin joints cases are bigger
Cheers from Maine, usa. very cool, haven't seen something like this before.
I had a question, what is the red bar you have with the roller bearing type things on either end?
Bulldog bending bar. Apparently.
I work on the railway doing HV Cabling and instead of a hacksaw Iâve started using a large pipe cutter works a treat just have to be careful! Good stuff anyways mate đđŒ
@@residualelectrical exhaust cutter we use, the ones that look like bike chains đ
Me too...just make sure the wheel is sharp so you don't turn in a burr.
Who makes that orange drop tool bag? I work in dust on grain sites and that would be elite.
You need to get a bandsaw mate perfect for cutting those big cables, safer than a grinder too. đđ»
Yeah the Milwaukee portable band saws come in different sizes and they are pukka. However I bought the Hilti version which is just that bit better.
Awesome
What size Swa is the cable in the video looks like a 240 or a 185 Iâm curious
You should pick up a dewalt portable bandsaw I love to use it to chop cables down instead of using a grinder the blades last a while.
The connectors we use at spen are shrouded saves firing insulation and tape over them
are them jointers insulated, or is it just the resin that stops them arcing together with how close theyre jointed
Thanks for the reply, really good video something Iâve never seen done before
I probably would have seperated the conductors with stand offs and then let the resin cover it all, my only worry with the insulation tape would be the air pockets filling with water.
i know old video, thought the waste material as extra insulation was a good idea. was the insulation tape needed? i would have thought it may stop the resin getting between all the cores?
@@residualelectrical not to worry, thats why they make the resin black, no one will ever know!!!!
The that join the armour are called Costa by force springs.
now try it again..... live đ not knocking you, you made a tidy job of it đ
Where did you get the oval tool carrying bag/mat thing from?
What tool bag are you using as a work surface?
What is that orange tool carry you used in this video? I need one of those
A day to do the joint, a week to get the mud off all of the tools! :-)
great video boys, "a bit like icing a cake" think your sister would disagree with that lol x
Short between phases: Well we're not even livening it up anyway đ
470 is going to come down pretty fast as the insulation between them is boiled off.
Take it the old armour slice wouldn't work on it đ€Łđ€Ł
You good job! đâ
Great vid đđ» what jacket are you wearing? It looks a good'n
That was intenso reminded me of the Blair witch project
I thought you would put some heat shrink around each connection before resin it.
i'm probably wrong, but wouldnt a clear resin make it easier for the next person who has to work on that/ do maintenance in the future? or is the idea that this will never have to be repaired
don't think you'd attempt a repair after potting it with resin.đ
Is there a problem with contamination at joints because of different metals coming together the aluminum to copper connection
@@residualelectrical gotcha thank you for the explanation
good vids keep it up
What adapter do you use on the impact mine always snaps ?
Thankyou đđ»
Great video. And to think my mate does that live!
@@residualelectrical I know. Like you He does a lot of cannibis disconnects. But I never seen a video of it. Thank you for sharing.
Love the part at 0.19 where he says âweâre going to start the joint nowâ how ironic!
Just started following your channel., what do the metal blocks do at 8:30? Is there any effect from staggering them vs doing them inline besides giving you additional space? Awesome content, thanks!
Space and so you don't touch leads. This is electric after all...
Think you have done this before đđ
Lots of joints at a cannabis farm I imagine.
I don't know if it's a good idea using impact to those ripe of screws, I mean maybe they break from the stress, not the torque. In the UK you don't use crimping connectors?
Here in Hungary we mainly crimp those type of cables, and also use really thick heat shrink for every wire, because you have to have double insulation.
@@residualelectrical yeah, I know. Aren't the shear off bolts purpose is to make sure you tightend it to a certain torque, so you don't have to use a torque wrench? My concern is that if its tightened with an impact gun, the way the tool tightens it maybe break it prior to achieving the desired torque setting.
You are right Gra, Iâm a jointer live LV-33kV in UK we shear off instead of crimp now and the impact gun can damage the threads. But for some reason we donât crimp. Probably for speed thatâs all mate
Yup, shear bolts should be tightened with a steady hand and wrench not any kind of impact device to ensure the torque is properly reached.
are those aluminum concentric neutrals?
american sparky here what is the separation from commercial to industrial electricians for you guys? this seems like more of a commercial task to me. just curious, great explanations on everything!
I have really enjoyed this, always wondered how this was done :)
