"Liquid" wire?

Question

Do it yourself

Greetings! Maybe there are people here who have come across such wires.
Interested in any information, to a greater extent, of course, the one that can be used: manufacturers, brands, types, markings, where to buy ... You can send it to Google, but it is desirable to be more specific. Anyone who held such a wire in their hands probably already understood what I mean, but I will add a few words.
The cross section of the wire is 1.5 square. The wire, by feeling, has a supernatural heaviness, the vein consists of 100,500 individual veins. It can be said that there is practically no filament - a very big step, and there is no division into groups either - the entire central vein is monolithic. It is quite possible that they are isolated from each other by the type of licensor. The insulation is quite thick, silicone or PVH, but very fluid. The wire itself has the flexibility of a rope, as it is laid, so it lies.

Answer 1

It's called a servo cable.

Answer 2

Under the description, acoustic cables partially fit, but most often the winding in them is still noticeable. Expensive speaker cables are often very flexible and contain many strands.
I dealt with Oehlbach, though with a section of 4 squares. The bay at 6 meters was really heavy and the cable itself is very flexible (almost like a rope).
They look something like this .

here I once took such a wire. But for some reason it seems to me that it is still in many places ... it is popular with modellers. On ebay www.ebay.com/sch/Radio-Control-Control-Line-/2562/i.html?_sop=15&_from=R40&_nkw=silicon+wire

Answer 4

In aircraft modeling stores, you can ask around for a wire in silicone insulation or look after it in China , the wire is very soft and the insulation does not melt when soldering.
