Ah yes, I stand corrected thought it was from the USthat video is from New Zealand
I think the correct winding of the oil impregnated paper, how its wound to prevent unravelling
after it has been jointed, will need more attention than how the lead sheath is removed
I don't think hot fill compund will affect the paper either
When you watch a skilled jointer at work, it all looks very easy, it's not!! But many ''Think'', i can do that, but rarely if ever Can!! lol!!
It was part and parcel of an apprenticship for many sparks in the state run heavy industries.ie to make off these type of joints and couplers
You were also tested and graded on your performance
A cable jointer will make it look very easy,yes,however,trainee sparks in these industries got the degree of difficulty made very well aware to them by having to do practice these joints techniques
I for one would admit that cable jointing is one fascinating skill to watch and admire,their skill will surely never get completed diluted like our own has unfortunately
Only ever seen the older covered PILC/SWA cables then, i can't say i've ever seen them with a PVC outer sheath, only that impregnated/tarred hessian. lol!! I know removing the lead sheath can be a real hassle if you don't know what you're doing. Only ever help make off a couple of PILC/SWA joints and one or two terminations. They were all wiped joints and terminations, that i took no part in, so i'm no expert with PILC cables. In fact i've never used them since, removed plenty of them though!! lol!!
I bet they don't let them practice too much on modern day joints etc, the typical cost of a 3 core 11KV cable heat shrink joint, is or was the last time i looked, around the 300 to 400 quid mark!! lol!!
Out of interest what is the correct way to strip it?
I've watched the man from the dno do it a couple of times and he used an insulated tool with a tiny blade at the end which he jest tapped along the length to split it.
Just have a look for the price of a cast iron, lead sleave (BICC) 11KV joint. It will make you're eyes water!
I was taught both at work as an apprentice and later by the EMEB the easiest, quickest method.
With a (Stanley) knife score around where you want the lead to terminate. From that circular score make two parallel “tram tracks” about ½“ apart to the cut end of the cable. At the cut end open up the two score lines with a heavy hack knife and a hammer. This will give you a tag that you can get you’re pliers on. Peal it back just like opening a can of corned beef. Once the strip is removed the lead sheath is just pealed off. Doing it this way the lead termination is slightly belled out thereby preventing a sharp edge against the cores.
The belting papers just after the lead should be bound for ½“ from the termination. The belting papers are then unwound to the binding and torn off. I’ve always use waxed string whipping to terminate the belting. (I’m old fashioned)
