High-purity CopperMade with 99.9 percent pure copper wire with anti-corrosion plated Tin, 34 strands 2 conductors, 0.14mm diameter per strand, a high strand count in each conductor which makes it optimal properties of high conductivity, maximum heat dissipation and easy bend without breaking. Low EccentricityUniform-thickness wire skin produced by high-tech, prevents current breaking through and ensures the safety of electricity. None changeable position of stands within the color-coded inner PVC jacket, ensuring that the electrical properties (capacitance, impediance) stay constant and do not influence the signal negatively. Eco-friendly PVC22AWG insulated with eco-friendly and odor-free white PVC material, is very tough, and also offers some resistance to damage from UV. The inner insulation on the conductors is color coded (red and black) to help insure your connection with proper polarity. With good insulation of inner and outer PVC jacket, wire wouldnt burn after
