High Conductivity: 41 strands of 0.16mm Pure Oxygen-free copper are inside each cable. High precision Oxygen-free copper conducts electricity well. Compared with aluminum materials, it has lower resistance and higher conductivity. Durable Material: The jacket/insulation materials are PVC(RoHs), which protects the wire against abrasion, resistant to sunlight and chemicals. The rated operating temperature up to 80/176. Easy to Use: The Red & Black Pure coppe Hookup Wire is flexible, easy to solder, that is for low voltage(5V-12V-24V-120V-240V) installations. Wide range of uses: low-voltage cable extension cords are very suitable for LED monochromatic light strips, electronic appliances and equipment, transformers, led lights, led splitter connections,Automotive,Ship,outdoor spot lights etc. High Quality: We commit to provide high quality products and customer satisfaction, The electricity wire we provided passed UL harsh testing that guaranteed long lifespan usage.
