Stripping the copper wires from abandoned cables can bring certain economic benefits, but attention needs to be paid to safety, environmental protection and legality. The following are efficient and safe wire stripping methods and important precautions： --- ###**1. Efficient wire stripping method** 1. **Manual wire stripper method** (suitable for thin cables) -Use special wire strippers (with blades of different diameters) to clamp one end of the cable, rotate the pliers to cut off the outer insulating skin, and then pull out the copper wire. -Advantages: Cheap tools and simple operation. -Disadvantages: Low efficiency, only suitable for small or thin cables. 2. **Utility knife/wire stripping knife stripping method** -Fix the cable, cut the insulating skin lengthways with a knife (pay attention to avoid hurting the copper wire), and then tear the outer skin. -Skill: You can soak the cable in hot water to soften the insulation layer (especially effective for rubber skin). 3. **Electric wire stripping machine** (suitable for large-scale processing) -The small handheld electric wire stripping machine can automatically peel off the outer skin, which is extremely efficient. -Suitable for professional recyclers, but the equipment cost is higher (about one thousand yuan or more). 4. **Fire burning method** (use with caution) - Burn the insulating skin in a ventilated place, leaving copper wire (the combustion of materials such as polyvinyl chloride will produce toxic gases). -**Not recommended**: Pollutes the environment and has a high risk of breaking the law. --- ###**2. Key precautions** 1. **Legality** -Confirm that the source of the cable is legal, the abandoned cable may be the property of others or the remnants of public facilities, and private disposal may involve theft or destruction of power facilities (Articles 118 and 264 of the Criminal Law). -It is recommended to contact a regular recycling company to provide proof of source. 2. **Security risk** -Wear gloves and goggles to prevent cuts or insulation materials from irritating the skin. -Check whether the cable is charged (even if it is discarded, there may be residual current). -Incineration will release carcinogens such as dioxin. It is strictly prohibited to burn in residential areas or in the open air. 3. **Environmental requirements** -The peeled insulating skin needs to be classified and disposed of according to garbage (usually hazardous garbage) and cannot be discarded at will. 4. **Economic considerations** -The price of copper fluctuates with the market (about 60-70 yuan/kg), and it is necessary to evaluate whether the labor and time costs are cost-effective. --- ###**3. Suggestion process** 1. Confirm that the cable has no owner and can be processed legally. 2. Choose the right tool (manual for a small amount, electric for a large amount). 3. Operate in a ventilated environment and properly dispose of waste materials. 4. Sell copper wire to a licensed recycler (registration of identity information is required). --- If the amount of cable is large or the source is uncertain, it is recommended to contact a professional recycling company directly to avoid legal risks. Safety and compliance should be the first priority!
