The regeneration process after cable recycling is quite simple. Initially, the collected scrap copper is sorted. Uncontaminated scrap copper or copper alloys with identical compositions can be melted and reused directly. Heavily contaminated scrap copper requires further refining to remove impurities. For mixed copper alloy scrap, melting and composition adjustment are necessary. After such regeneration treatment, the recovered cables are completely updated, with no damage to the physical and chemical properties of the copper.
What are the requirements for wire and cable recycling?
1. Look at the packaging, the standard national standards for wire and cable recycling usually have good quality, neat, and feel substantial in hand.
2. Be sure to open the packaging and inspect the wires inside. National standard wires with a cross-sectional area of 1.5-6 square millimeters require an insulation thickness of 0.7mm, which is quite thick. Anything thicker is non-standard and would likely have an insufficient core. You can give the wire jacket a good pull; if it's not easy to tear, it's generally in compliance with national standards.
3. A flame test shows that it extinguishes within 5 seconds after being removed, indicating it has the required flame-retardant function in accordance with the national standard.
4. Inspect the core: The higher the brightness of the core material (copper), the better the quality of the copper, with even brightness and a lack of layered texture. National standards require the core to be made of oxygen-free copper. Non-standard wire and cable recycling, such as black rod copper, may pose safety hazards.
5. The core thickness has certain national requirements, but they are not very strict. However, it won't be off by much; just a very small, usually imperceptible error to the naked eye.
6. Length is not mandatory to be marked in meters by the country, but many manufacturers do so. Those marked in meters are not necessarily in accordance with national standards, and generally, national standards do not include marking in meters. The marking in meters for non-standard wire and cable recycling is just a method.
7. National regulations stipulate that electrical wires must be marked appropriately. A consecutive marking will be applied every 500mm or less, typically featuring the product's brand, the name of the wire cable recycling manufacturer, and the execution standards.
Recycled Cable Recycling
Cables that cannot be used normally are all categorized as scrap. Some cables are returned to the manufacturer for repair and replacement, while others that are not replaceable are typically disposed of as scrap copper. The processing is entrusted to local scrap material recyclers who purchase and process the cables, stripping them for copper. The recovered copper is then sent to copper factories for cable production or other copper products, or it is directly refined into copper ingots.
As the usage of wires and cables continues to rise, so does the frequency of upgrades and replacements, leading to an increasing amount of waste for disposal. The recycling and reuse of old wires and cables has become of significant importance.
