This is 20 AWG shielded wire with Cross-Linked ETFE outside insulation. The inside wire is silver plated copper stranded with 19 strands. The color of the inside wire is white.  This is shielded with a silver plated copper braided shield. The shield wire is flat for greater coverage and smaller outside diameter.  The outside is a Cross-Linked ETFE insulation jacket. This is very high quality mil. spec. wire. The mil. spec number is M27500A20SR1G23. This has a much smaller outside diameter than the same size with just PTFE insulation that has round braid wires instead of flat. The overall OD of this wire is aprox. 0.0740 inch (1.87mm). I will ship Worldwide. This is a 10 foot length of wire. If you buy more than one I will ship as a continunus length.
