Worth Buying KYNAR Cable for Small Electronics up to 20V? - Advantages & Uses

Hello.
As in the subject.
Does such a cable pay off in small electronics up to 20V?
I know that he has the wire inside because I have it.


Gives the cable off.

Yes. Very good at saving damaged paths on PCBs, as jumpers, for test assembly (so-called "spider"), etc. For other applications rather not necessarily.

AVE ...

I use such kynar all the time when performing layouts on universal plates. When I need larger currents, I take a piece of twisted pair or telephone cord, but it works great in small signal systems. I used it several times in Joule Thief circuits as an auxiliary winding. The only drawback is that it can crack when it is bent too often, so except for rigid tiles it is rather unsuitable for anything ...

OK, so it works perfectly?

In the repair of delicate joints, yes. Provided you mean real kynar, not Chinese fakes.

I mean the kynar like the picture.
Which one is original and which is a fake?

Maybe a little off topic - Caring for the correct spelling is (in my opinion) the same as the neatly drawn diagram. In electronics (as well as in spelling) there are certain rules and rules and they should be followed - whether you like it or not. This makes it easier to convey the content of your speech, or facilitate deciphering connections in the diagram.
And we are in the technical forum ... so I think (?) You should make sure that others do not have trouble guessing "what the poet meant"?

This photo, commonly known as kynar, is externally very similar to it but differs from the original kynar in terms of insulation material.
The kynar cable (actually the name kynar is the name of the material, not the cable) is much more resistant to temperature (Tefzel is even better) and mechanical exposure.
The downside is the difficulty of stripping and a good price.

This wire, which you have in the picture (usually called incorrectly kynar), is less resistant mechanically (on sharp edges it can easily break through) and thermally (melts at soldering temperature). Although in a lot of applications it is not bad at all, especially at this price. I also use it, where you don't necessarily need the original kynar or tefzel.
Isolation is removed even with nails. And as careful when soldering and do not heat up much and avoiding stretching at some edges, it is suitable e.g. for mounting on universal boards or for permanent connections inside devices, better than other solutions, e.g. so-called telecommunication wires, etc.

If you need it, yes.

It wasn't even with kynar. It's a patch in PE insulation.

Thank you. I'm closing the topic.
