Stripping copper wires from abandoned cables is a task that requires careful operation, because cables may contain harmful substances, and improper operation may cause harm to health and the environment. The following are some effective wire stripping methods, but please be sure to pay attention to safety and environmental protection： ### 1. **Manual wire stripping method** -**Tool preparation**: Prepare a sharp wire stripper or utility knife, gloves and protective glasses. -**Operation steps**： 1. Wear gloves and protective glasses to ensure safety. 2. Fix the cable on a stable workbench. 3. Use wire strippers or utility knives to gently cut the outer skin along the length of the cable, be careful not to cut too deeply to avoid damaging the copper wire. 4. After peeling off the outer skin, pull the copper wire out of the outer skin by hand. ### 2. **Mechanical stripping method** -**Tool preparation**: You can use an electric wire stripping machine or a manual wire stripping machine. These devices can quickly peel off the outer skin of the cable. -**Operation steps**： 1. Put the cable into the wire inlet of the wire stripping machine. 2. Start the machine, and the wire stripping machine will automatically peel off the outer skin, exposing the copper wire. 3. Collect the peeled copper wire. ### 3. **Fire burning method** -**Tool preparation**: Fire source (such as blowtorch), gloves, protective glasses and a well-ventilated environment. -**Operation steps**： 1. Do it in a well-ventilated place, wearing gloves and protective glasses. 2. Use a fire source to soften the outer skin of the cable, be careful not to burn to the copper wire. 3. After the outer skin is softened, quickly peel off the outer skin with a tool to expose the copper wire. ### 4. **Chemical stripping method** -**Tool preparation**: Chemical stripper, gloves, protective glasses and a well-ventilated environment. -**Operation steps**： 1. Do it in a well-ventilated place, wearing gloves and protective glasses. 2. Soak the cable in a chemical stripper and wait for the skin to soften. 3.
