It is my understanding that the following terms apply. If not, please elaborate/correct.
Braid - bare small gauge wires woven into a general hollow tube shape, intended to be used as shielding Ribbon - flat shape, multiple conductors insulated from each other, solid or [7? wires bare fibre wires?] to make each conductor. Solid Ribbon - flat shape, multiple conductors insulated from each other, solid wire conductors. Is this right? Robert > Brian: > > I include braid in the category of ribbon without distinction.
