This is a great product, been using it for years. I can leave it in the back of my van though summer and winter temps and it still performs well every time i need it.
Used to use this stuff in my aprentaship for pulling hydraulic hoses and its a abosulte must I still use it today in various applications in maintenance engineering and at home doing my cv boots its verry good like you say it doesn't eat in to the plastics and rubbers
Ludi made by 3M is the stuff that we use. Of course here pulling cables is a very common thing for electricians, because we install all circuits with tubing (copex) and H07V-U or N05VV-U
Cable lubricant helped us to pull a cable through an underground 40m conduit which we could not get through unlubricated. Highly recommended you do this on difficult installations. And....the lubricant dried off the cable within a couple of hours
The only trouble I have had with Y 77 is when applied with your hands and have no means of wiping it off it's a bit of a faff to try gripping the draw wire ,but overall it's good stuff.
good stuff.. BUT... how much of the cable did you lube up? and, if its all, and you got to run 30 metres, how much time to lube up all the cable, this is a great "lab" test, but nothing beats a real world field test.
Time doesn't matter, this is low volt datacomm cable. You have to be veryyy careful with the amount of force your using, you can easily damage the cable!
@@brandonkick I specialise in structured and fibre, have done for many years so are very aware of nm forces (oh and time is important when some jobs are invoiced at qtr hourly rates)
In the US we have an insulation that actually pulls better without lube. The yellow 77 is last century. Literally. There are pulling compounds out that don't dry to a thick waxy paste like 77 does. That said we still use wirenuts :P
@Tommy Mack wagos cost way more, failure rates are similar and wagos take up more space. That being said, in large JBs I use wagos. In switch boxes or outlet boxes I use wirenuts
what do you recommend for trying to remove existing cables from conduit? 14-3+ground cable is really stuck. Already tried a dry pull of 400lbs and didn't budge. one end is a few feet higher than the other, i was thinking to pour soapy water until it came out the lower end. Assuming that will loosen it up and allow it to break free. Then after removing the cable, blow out the conduit with the shop vac. THoughts?
Hi, i have a big problem. My pool light needs to be replaced. It runs through a pvc 3/4 conduit. Wire wont budge. How do i lube a dry conduit that's already full of wire ?
Simple test well elaborated. It’s about friction and pulling tension, the other main reason you want lubrication more than even ease of pulling through conduit is to reduce friction burns that can damage cables. With data communication cables you have to be very careful on pulling tension it needs to be kept very low to avoid damaging its critical properties of conductance communication that enable it to operate effectively here it’s not even about friction burns just straining the cable is a big problem - always use lubrication for those unless it’s a very simple straight run with no bends and single cable in conduits. Can you try the comparison of the polymer based clear ideal lubricant gel against the yellow 77. Yellow 77 is wax based which can form lattice based structures when dried and make removing them in the future more challenging. Polymer based ones work better on all types of cable including data communication cables and optical fiber for which yellow 77 should not be used. I understand you are bringing this to electricians for information but it’s critical you highlight where and when it should be used and where it’s not the right product, it’s very important. The product has been around much longer as you said in the states. We have developed a much greater understanding of it. Many here have moved onto other lubricants. Especially in the time saved in clean-up and less staining with polymer based ones. There are silicon and Teflon based lubricants as well. In fact manufacturing today in the states are producing slicker cables that allow ease of pulling without use of gels and still maintain excellent insulation properties for the cable and conductors. Take a look at this article it goes into some depth on the topic: www.cablinginstall.com/design-install/cabling-installation/article/16465756/cablepulling-lubricants-lower-friction-and-pulling-tension
Hi. I like the info about the fact of how 77 is made up of. I am an old elect. Stopped now. But I just to use Talc to put on my wires as I changed from good old cutting grease yes good old days.
One mistake I see when using lube, is that they put the lube onto the beginning of the cable. Give yourself enough cable so that it comes out at the other end of the conduit not covered in lube
Not that this does not work but the demonstration could be fixed and is not representative of a real application. One would rather see a long pull of wire and see the application and set up in full view. Looking to get some lube for a wire pulling application myself but need to pull wire 75 feet or more. This demo does nothing for me.
going by Eland's spec for 6491X, total cross sectional area of the cables is 13 x 3.14159 x (2.9mm / 2)^2 = 85.9 mm^2 total CSA assuming that the internal diameter of the conduit is 19mm (estimated) then it's internal CSA is 3.14159 x (19mm / 2)^2 = 283.5mm^2 total CSA the conduit is therefore 30.3% full and compliant
@@dg2908 that's some nice calculations but it just doesn't seem to line up with reality, did you take account of the insulation? Infact referring to the onsite guide Appendix for cable capacities in conduit with bends. Let's say the conduit is 2m long and has two bends, that gives a total allowable cable factor of 256. Each 1.5mm cable has a cable factor of 22 256/22 = 11.6 So you would be allowed a maximum of 11 cables in reality.
If I'm honest I didn't even know that was in the OSG. In my predominantly domestic work I occasionally use conduit and rarely singles. I do that kind of calc for trunking near boards sometimes but derating for grouping is much more of a concern there
@@efixx love your channel & content but this particular post....Might as well made one called " do m.c.b's serve a purpose" or " is conduit good for protecting cable"
