In a sense, the wire and cable manufacturing industry is a material finishing and assembly industry. First, a large amount of material, the cost of materials in the cable products account for the production of cable 80-90% of the total cost; Second, the types of materials used, the type is very large, high performance requirements, such as conductor copper, copper The purity should be above 99.95%, and some products require the use of oxygen-free high-purity copper. Thirdly, the selection of materials will have a decisive influence on the production process, product performance and service life. At the same time, the benefits of wire and cable manufacturing enterprises are also closely related to the selection and processing of materials as well as the scientific frugality of materials in the production process. Therefore, in the design of wire and cable products must be selected with the material at the same time, through the process of material properties after many experiments to choose. Cable products with the structure and function of the distribution of materials can be divided into conductive materials, insulating materials, filler materials, shielding materials, sheathing materials. But some of these materials are common to several structures. In particular, thermoplastic materials such as PVC, polyethylene, etc. can be used on insulation or jacket simply by changing the composition of the ingredients.
