Low-grade insulated copper wire refers to copper wire that is covered or insulated with a low-quality or non-valuable insulation material. It is a type of scrap metal commonly found in electrical wiring, cables, or electronic devices.

Low-grade insulated copper wire typically contains a copper conductor covered with insulation made of materials like PVC (polyvinyl chloride) or other non-valuable polymers. The insulation on this wire is often of lower quality or has a lower copper content compared to higher-grade insulated copper wire.

Recycling low-grade insulated copper wire involves the process of separating the copper conductor from the insulation material. This can be done through mechanical or thermal methods, such as stripping or burning the insulation. Once separated, the copper can be recycled to produce new copper-based products, while the insulation material is typically discarded or used for alternative purposes.

While low-grade insulated copper wire may have a lower value compared to higher-grade copper wire, its recycling is still important as it helps conserve valuable copper resources, reduce waste, and minimize environmental impact.
