Stripping the copper wires from cables requires careful handling to ensure safety and efficiency. Here are some common and effective wire stripping methods: 1. **Manual stripping tools**: Use a dedicated wire stripper or cable stripper. These tools are designed to remove cable insulation, are relatively simple to use, and are not likely to damage the internal copper wires. 2. **Knife stripping**: Carefully cut the outer sheath of the cable with a utility knife or multi-purpose knife. For thicker cables, you can draw a straight line along the length of the cable and then strip the insulation. Be careful not to hurt the copper wire inside or yourself. 3. **Heat treatment**: Use a heat gun to heat the cable to soften the plastic insulation and then strip it. This method requires caution to prevent overheating and damaging the copper wire or producing harmful gases. 4. **Mechanical wire stripping machine**: For large quantities of cables, using an electric wire stripper can greatly improve efficiency. Adjust the appropriate settings according to the size of the cable, and the machine will automatically strip the insulation. Precautions: - Make sure to use personal protective equipment such as gloves and goggles. - During the stripping process, make sure the cable is not energized to avoid the risk of electric shock. - If you are unsure of the source of the cable or its purpose, it is best to consult relevant professionals or institutions before handling it to ensure there are no legal issues. No matter which method you use, please ensure safety first and comply with local regulations.
