Non-standard wire twisting. Excellent contact and strength

Back in the spring I posted a post on the channel about a very reliable twist wires from the point of view of mechanics (i.e. break), however, there the wire is ultimately wound on itself, which is not very good in terms of the magnitude of the contact resistance. In this version, this disadvantage is minimized. See for yourself!

I use homemade insulation stripper - stripper. For demonstration, I strip the wires with a margin, their cross section is 2.5 squares.

At the first stage of making the connection, the wires simply hook onto each other without twisting - with a hook. One of them was conditionally on top, the other on the bottom. Now I prepare the edges for the subsequent overlap and loop formation. The top wire still remains on top.

The most difficult thing is to make a neat overlap, winding the wire loops into each other, after which it remains to properly pull the ends. In this matter, it is possible, and even desirable, to help with pliers.

The main thing is that as a result of tightening, the ends of the wires are turned towards the neighboring wire, and not themselves. Accordingly, they will wind up in the same direction.

From above, after a full tightening, a small "bulb" is obtained, which in this form will stick out from under the insulation. I'm not touching it yet, but I'm starting to wind the edges. This gives us a connection that retains high mechanical strength and provides excellent contact between the two wires.

The transition resistance with such a bundle of wires drops significantly and the twist will not heat up, which means it is safe.

In the end, it remains to bring the twist to its best form. For this purpose, I crimp the "bulb" with pliers and everything changes at once. I also tried to break this connection, but nothing came of it. So, I think, both in terms of mechanical strength and safety, the connection is very reliable.

It remains to insulate with electrical tape or heat shrinkage and you're done. Now I am waiting for your thoughts and assessments of this method of twisting.
