Hi
I bought this cable here https://www.audiophonics.fr/en/cabl...lded-power-cable-occ-553mm-o165mm-p-6456.html
Now I need to remove the Teflon insulation surrounding each conductor, it's really thing as you can see on the pictures. I would really like to avoid damaging the copper stands, I already had to cut away 3cm of cable because the only way I managed to remove the Teflon was with a knife and peeling it a way like potatoes. I tried 3 different cable removal tools (see picture= and couldn't get any to work, maybe they are not suitable for this situation I am not sure.
It's really elastic, almost like chewing gum and it's a very thin layer.
Suggestions are welcome, I have never done this before.
Best regards and ty vm

Oh those will not work. You would need to use a cable stripper pliers similar to the ones below. These pliers will cut the insulation around the copper core (notches prevents you from cutting the copper).

The "japanese" wire strippers also can strip these cables. Almost any wire stripping tool with 2 sharp halfround knives (not touching the copper!) will do. All 3 pictured wire strippers only touch the insulation at opposite sides. That is not enough for teflon.
These are quite good for most wires: https://www.knipex.de/produkte/abis...essern/abisolierzangenmit-formmessern/1221180
Please note a version exists for smaller diameter wires. I have one and it is one of the best I have.

Hot wire strippers are available for Teflon.
They will NOT damage copper below,since no sharp edges are involved, at all.

I was considering this one, it's 20 euros
Seems to cut clean, only issue I see is that considering you have to insert the wire strand into the tool all the other strands would get in the way.

2nd one is easier to use as the holes are made for different diameter. But don't get them from the website, it's too expensive. You should be able to find cheaper ones from china for less than usd10.
Another solution if you do not have any tools is to use a paper cutter. You can use the paper cutter to cut into the insulation and then use existing wire stripper to rip the insulation out. It will be much easier.
I use the Klein brand wire cutters strippers with the curved handles. They work from gauge 6 to 28 and bolts too. I test and see which cutter goes all the way through the jacket without damaging the wire. I them use my fingernail to slide off the jacket giving it a very slight twist both ways. Many times the labeled gauge is not exact so test it first. You can also grab the jacket very gently with the cutter part of the tool to tug off the jacket. The reason I don’t use the tool to pull it off is it often digs in to the copper. It isn’t that hard once you get a hang of it.
The quality of the famous Kaiweets tools seems questionable. Maybe good old EU brands make better stuff. There is no substitute for working with good quality tools.
Are you in the EU? I may have one of the original Japanese wire strippers new in box.

A sidecutter as used for mains wiring; put some pressure on the isolation without cutting through it, and then rip it of using an axial movent.
or
A sharpe knife, cut the isolation with an axial movement while holding the side of the blade parralel to the core.

Maybe you can DIY one, using a battery, a piece of Nichrome wire and some kludged support for it.
Probably made out of wood; metal will short the filament and plastic will melt ... unless you use Bakelite or similar.
Today as rare as Hen´s teeth.

Off the net, no ties to seller.
This works, I set it slightly proud of the wire, and rotate the tool around after pressing it in, so the cut is full round, then a gentle pull breaks off the remaining insulation.
With practice, the conductor is not damaged.
Bakelite is still used in electrical power, controls distribution equipment, transformers, so still readily available here. There was another type we used also, but can't remember and couldn't Google anything similar, just lists PVC, which couldn't come close to passing UL/CSA testing in '94 when the plant closed.
In India, we get:
Sheets from 1 to 25 mm thick.
Fibre glass filled, jute filled, plain
Up to 8 x 4 feet sheets.

The only issue with these is the cutting edge is not rounded and as a result the jacket is not completely cut and it make it a hassle to pull off. If you really want to save money just use a single edge razor blade and gently roll the wire with the blade lightly cutting the Teflon jacket. Give the jacket a slight twist both ways(clockwise and counterclockwise) pull it off. If you practice this you’ll get good at it and cut no strands of wire.
