Short answer: Thin wire is stripped efficiently with a machine or by running a knife along a length and peeling it, which is quick for single conductors but slow for fine cords, while thick cable is best slit lengthways and peeled or put through a heavy-duty stripper, and for very fine multicore cord it is usually not worth the effort and is better sold insulated.

List Free →Thick cable
Slit the sheath along its length with a knife or tool and peel it back to release the conductors.
Single-core wire
A machine feeds the wire through and strips it quickly, which suits regular volumes.
Fine multicore cord
The effort per kilogram is high, so this is the best candidate to sell as it is.
