Places that buy scrap metal will not buy wire if the insulation is still attached.
This is because they want to melt it down right away so it can be quickly sold.

The insulation gets in the way of this process and cannot be melted down along with the wire.
An automatic scrap wire stripper can help you strip the insulation from the wire very quickly and easily.
