This is a very high quality and sharp looking wire. This is a twisted pair with 2 inside conductors that are 16 AWG silver plated copper wires. The inside wires are stranded each with 19 strands. They have polyamide film (Kapton) insulation with PTFE covering. The colors of the inside wires are red and blue. This is then shielded with a silver plated copper shield. This cable then has a polyimide film outside insulation. This is a very high temp. wire.  This would be good for audio and other applications. This wire is rated at 600 volts 200 C. This is lighter and has a much smaller outside diameter than the same size with just PTFE  insulation. The OD of this wire is aprox. 0.1480 inch (3.76mm).  I Will ship Worldwide.  Please check my eBay store for much silver plated wire. This is a 25 foot length of wire if you buy more than one I will ship as a continuous length.
