High Quality Tinned Copper Wire: the purpose of tinning is to protect the corrosion resistance and abrasion resistance of metal substrate. Tinned Copper Terminal: this wire is a power extension wire, not a module wire, so it supports any ATX power supply to connect the colored extension wire to the original power line interface with stable conductivity. Double Light Source Design: the product has a utility model patent design patent. Super Flexible Wire of Arrayed Optical Fiber: bottom power extension wire structure: the innermost layer consists of 41 tinned copper wires; Wrapped with intermediate PVC insulator; Bottom, nylon woven. Process: Nylon Braiding Process+Arrayed Optical Fiber; Material: 18AWG 41 * 0.16 Tinned Copper Wire; Length: 245mm; Product Structure: Nylon Braided Extension Cord at the bottom, Surface Arrayed Optical Fiber, Dual Light Source Design; Home Decoration Project: BVR (Multi Strand Flexible Wire)
