High Quality 12 Gauge Silicone Wire -- 25 ft Red and 25 ft Black, total 50 feet. Super low impedance & highly efficient! Rating Voltage 600V - 12 gauge wire is also suitable for all 12V ~ 600V projects. Ultra Flexible 12 AWG Wire -- Combine with high count thin strands copper conductor & soft silicone rubber insulator, the construction makes 12 AWG copper wire with amazing flexibility. 100% Tinned Copper Conductor -- 680 Strands 0.08mm Stranded Copper Wire ( 3.42mm2 ) Rating 36A. Every strands copper is tinned, the outer tin layer can protect copper from been oxidized. ( Note: 0.08mm Tinned Copper is too thin to check inner pure copper, So people always doubt it is aluminum wire. We can use fire burn the conductor around 5 seconds, The inner copper will be appeared. ) High Temperature Resistance: 392/200 -- Silicone rubber as a thermoset material, it will not melt in high temperature. However, PVC or PE insulator will start melt over 176/80, it will cause Electrical sh
