In modern electrical installations and power transmission, Twin and Earth Cable-also known as TPS Cable-is one of the most common and indispensable cables. Not only does it ensure safe and stable power delivery, but it also contains high-purity copper conductors that hold significant economic value. While many people know Twin and Earth Cable as a standard wiring product, fewer understand why it is worth stripping for scrap or how to properly and safely strip it. This article explores the value of Twin and Earth Cable, why it is stripped for scrap, how to do it effectively, and what precautions must be taken. Finally, we will explain how choosing a trusted cable manufacturer can maximize both usage efficiency and recycling value.
The Value of Twin and Earth Cable
Twin and Earth Cable consists of two insulated copper conductors and one bare earth conductor. The insulation is typically made of PVC or low-smoke, halogen-free materials to improve fire resistance and durability, while the outer sheath provides mechanical protection. This simple yet efficient design makes it one of the most widely used cables in residential, commercial, and even industrial wiring.
The true value of Twin and Earth Cable lies in its copper content. Copper is an excellent conductor with high conductivity, ensuring stable electrical performance. Beyond its use in installations, copper retains significant market value after a cable has reached the end of its service life. For example, a 100-meter roll of 2.5mm² TPS Cable can yield several kilograms of pure copper when stripped, providing a considerable return for electricians, contractors, or scrap metal businesses.
Why Strip Twin and Earth Cable for Scrap?
A common question is: if you can sell used cables as a whole, why bother stripping them? The answer is profitability.
Selling unstripped cable means it will be valued as "mixed cable," which fetches a much lower price. Stripped copper, on the other hand, can bring in 30%–50% more on the scrap market. This price difference can translate into a significant profit margin, especially when dealing with large quantities of cable.
Another key reason is environmental responsibility. Cable sheathing is often made of PVC or PE plastics, which can cause environmental harm if discarded improperly. By stripping Twin and Earth Cable, you separate copper from plastic so each material can enter its respective recycling stream, maximizing resource efficiency while reducing waste.
How to Strip Twin and Earth Cable for Scrap?
The method of stripping depends on how much cable you have and the tools available.
For small amounts, a utility knife or electrician's knife is often used to manually cut open the outer sheath and peel off the insulation to expose the copper conductors. While inexpensive, this method is labor-intensive and requires skill to avoid damaging the copper or injuring yourself.
For medium-scale work, mechanical wire strippers are a much better choice. These machines allow users to feed the cable through while automatically separating the copper from the insulation, improving efficiency and reducing risk.
On an industrial scale, large automated stripping machines are used. These machines can process hundreds of kilograms of Twin and Earth Cable per hour, separating copper and plastic almost flawlessly and producing a high-purity copper output ready for resale.
Safety Considerations When Stripping Cables
While stripping cables can be highly profitable, safety must always come first.
Always ensure the cable is completely disconnected from any power source. Attempting to strip a live cable is extremely dangerous and may result in electrocution. Operators should wear insulated gloves and safety glasses to protect against sharp tools or flying debris.
When cutting manually, apply just enough pressure to slice the sheath without nicking the copper conductors. If using a stripping machine, follow the manufacturer's instructions carefully to avoid malfunctions such as jams or dangerous recoil.
Whether stripping manually or mechanically, safety equipment and proper training are essential.
