Plastic copper-core wires can be used for connections between power installations, lighting, electrical equipment, instruments, meters, and telecommunications equipment with AC nominal voltages not exceeding 450/750 V. The dataset includes major raw and auxiliary materials, energy inputs, and wastes from the production process; infrastructure such as production equipment and factory construction are excluded from the system boundary of the dataset. The life cycle inventory is compiled from data sourced from multiple references. The manufacturing process of plastic copper-core wires includes wire drawing and annealing, insulation extrusion, inspection and packaging.
