1. Classification of waste cables and wires.
Wire and cable products can be divided into five categories according to their use, namely bare wires, insulated wires, heat-resistant wires, shielded wires, and power cables. Among them, bare wires are mainly used for power or equipment connection; The insulated wire is used for the connection between electrical appliances or equipment and the power supply, which plays an insulating role; Heat-resistant wires are used for electrical connections in high-temperature places; The shielded wire is used in the environment with special electric field interference, which has the effect of isolation and anti-interference; Whereas, power cables are used to transmit electrical energy.
Second, the cause of waste cables and wires.
There are two main reasons for the generation of waste cables and wires: one is that the outer sheath and insulation of cable and wire products with expired service life are worn or aged, and new cables and wires need to be replaced; Second, due to technological progress, the newly developed cable and wire models have better performance, and the original cable and wire products have become waste. In addition, waste cables generated from some construction sites, road construction, etc., also fall into this category.
Third, the significance of waste cables and wires.
The use of waste cables and wires is of great significance for the recycling of resources and environmental protection. First of all, waste cables and wires still contain a large number of non-ferrous metals and other available resources, ** reuse can not only reduce waste, but also save natural resources. Secondly, waste cables and wires will produce a large amount of waste gas, waste residue and so on in the process of transportation, treatment, etc., if not treated, it will cause pollution to the environment, and scientific and reasonable treatment is conducive to the protection of the environment.
Fourth, how to correctly ** waste cables and wires.
1.Understand product information: Before the first waste cable and wire, you should understand the model, specification, production date, service life and other information of the product, so as to judge whether the product has reached the service life.
2.Classified storage: Waste cables and wires are stored in a classified manner for subsequent processing. Cables and wires of different models and specifications are handled differently, so they need to be handled separately.
3.Scientific treatment: When dealing with waste cables and wires, scientific and reasonable methods should be used for treatment. First of all, the waste cables and wires should be cut, then the outer sheath should be stripped off, and then cut to a suitable length for weighing and recording. For problematic cable and wire products, they should be properly disposed of to avoid pollution to the environment.
4.Safety during transportation: Safety should be ensured during transportation to avoid safety accidents such as traffic accidents or fires.
5.Find a professional company: In order to ensure that waste cables and wires are properly disposed of, it is recommended to find a professional cable and wire company. These companies have rich experience and technical strength, which can ensure the safe and environmentally friendly disposal of waste cables and wires.
In short, the waste cable and wire is of great significance for the recycling of resources and environmental protection. Understanding product information, sorting and storage, scientific handling, safe transportation, and finding a professional company are all key steps in getting waste cables and wires right.
