Hi, I'm the user who has many doubts . I know it can be crazy what I'm going to consult then, you can laugh freely.
I am in a situation where I can not get some rope dacron or any type of coated rope for the terminals lines covers, because I do not live near a metropolis and do not want to ask for a shipment of a few meters of rope. (this would be for traction lines)

So I think these two alternative options:
1: cover of cable electric
2: heat shrink sleeve of the electronic
(the loop I would with a knot)

It is plausible or crazy

I am from argentina, sorry for the traduction.

Thanks for your time

I've used this method. No sleeving material required. You do need a guitar string.

most of us have many doubts but live to tell another tale

I'll have to try ssayre's method - good video!. I found that wrapping the loose end with red or black polyester thread works great and colour codes the end for connection to the bridle. Use a hangman's knot to secure the thread.

The method in the video produces a very neat loop, however it is pretty difficult or impossible to do with a thin line like I sometime use for brakes or the 5-th. So I prefer a conventional sleeve+knot which can also be undone if needed.

but what I want to do is sheathed loops, equal to those seen in photos of CANUCK, to reduce friction on the line and prevent breakage. It is for traction lines.

I have sleeved like Canuck. I simply wrapped the tail with a bit of hockey tape. ( I am Canadian so that is what was in the drawer )
It wasn't the tail that was a problem with this method. It was the knots themselves. They are line grabbers.
I agree with your opinion and approach considering your limited resources. The SLEEVE is the important thing. Without it your lines will fail when you least want them to. The tangles can be sorted out on the ground when it is safe.

I stumbled across a bunch of Q-line. Great stuff since it doesn't need sleeved but I still live with the knots grabbing my lines.

I may be off base here, but Steffen Born has some simple elegant nylon little "wind socks" sewn on at the ends of his line sets. Here is a thread where there is a photo of them (you will need to scroll down the thread to the picture, the one with the bar and lines on a table):

These little guys do a wonderful job of covering up the knots and loops and are specifically designed to stop making the knots and loops points to get snagged or tangled. Just a thought - good luck!

On a side note, my son spent this past summer in Rosario in Argentina. He LOVED your country.

With power lines of 220 kg or so I no longer bother to sleeve them. I do sleeve thin lines. Needless to say I haven't broken a line that has not been previously traumatized in over 20 years of kiting - with one exception when I tried to use a stunt kite for propulsion in a gale force wind. And - of course - if using the "neat" method of making loops, they will be unsleeved. BTW the loops above seem to be way oversized for what is needed. I am not picky enough to suggest this would cause additional drag (as some would do) but I don't like to loose 1/2 m of line and sleeving which can be put to better use. So I make my loops very small, barely enough to squeeze the knot through after making the connection - you don't need double loop line to lark over the line you are connecting to. And I don't leave loose ends extending beyond the loop knot - never had a problem with slipping out. The resulting connection is quite compact with all knots being close together.
