Recycled cable materials typically exhibit varying degrees of aging, with additives suffering different levels of loss. Although the properties of recycled cable differ from those of new materials, recent research data indicate that by adjusting the formula and adding necessary functional additives, the processing, mechanical, and electrical properties of recycled cables can be improved. Different product requirements call for different process formulas and techniques. Specifically, the recycled cable material is melted and reprocessed, then crushed and mixed with an appropriate amount of functional additives for re-granulation, resulting in lining material, which is used for the inner sheath of power cables.
Due to varying requirements for characteristics, installation environments, and working conditions, the structural composition of wire and cable products also takes various forms. The basic structure of wire and cable typically consists of three parts: the conductor core, insulation, and sheath. The main manufacturing process involves three techniques: drawing, twisting, and covering. The more complex the models and specifications, the higher the repeatability.
1. Drawing. The technique of forcing metal through a mold (press roller) under external force, compressing the metal's cross-sectional area, and obtaining the required shape and size of the cross-section is known as metal drawing.
2. Twisting. To enhance the flexibility and overall integrity of wires and cables, two or more single strands are interwoven together in a specified direction, which is known as twisting. The twisting process is further categorized into conductor twisting, cable making, braiding, and wrapping.
3. Coating. Depending on the different performance requirements for wire and cable, different materials are used for coating the conductors. The coating process is categorized into: extruded coating: rubber, plastic, lead, aluminum, etc.; longitudinal coating: rubber, aluminum strips, etc.; wrapped coating: strip-shaped paper tape, mica tape, alkali-free glass fiber tape, non-woven fabric, plastic strips, linear cotton yarn, silk, and other fibrous materials.

Overall, China's technology for recycling and utilizing waste cables is not advanced, and the level of pollution prevention is low, posing serious environmental pollution risks. The recycling of waste cables is of great significance; it not only reduces costs and meets the needs of other applications, but also serves as an excellent environmental protection measure.
