This is a very high quality and sharp looking wire. This is a twisted pair with 2 inside conductors that are 22 AWG silver plated copper wires. The inside wires are stranded each with 19 strands. They have polyimide film (Kapton) insulation with PTFE covering. The colors of the inside wires are red and black. 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 (higher than just PTFE) 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. 0.0965 inch (2.45mm). I Will ship Worldwide. Please check my eBay store for much silver plated PTFE wire. This is a 10 foot length of wire. If you buy more than one I will ship it as a continuous length.
