23 AWG Shielded Multi Strand Wire - 7/0.193mm (Orange) 90 meter Avago technologis These are Metal Film ResistorThis is a shielded multi strand wire which is 90 Meter in length and orange in colour. It has a wire gauge of 23 AWG. A sheathed or shielded wire means that the main conductor cable is insulated, and has a common conductive layer (braided copper) around it for electromagnetic shielding. A multi strand wire has multiple strands of uninsulated wires bunched together into a single core. The single core is PVC insulated. This makes it a perfect solution
