Wire and cable are wire products used to transmit electrical (magnetic) energy, information, and achieve electromagnetic energy conversion. The broad sense of wire and cable is also abbreviated as cable, while the narrow sense of cable refers to insulated cable, which can be defined as: a collection composed of the following parts; One or more insulated wire cores, as well as their respective possible cladding, overall protective layer, and outer protective layer, may also have additional uninsulated conductors in the cable. The vast majority of wire and cable products are products with identical cross-sectional shapes (ignoring manufacturing errors) and elongated shapes, which are determined by the characteristics used as components of circuits or coils in systems or equipment. So studying and analyzing the structural composition of cable products only requires observation and analysis from its cross-section. The structural components of wire and cable products can be generally divided into four main structural components: wire, insulation layer, shielding and protective layer, as well as filling components and load-bearing components. According to the usage requirements and application scenarios of the product, some products have extremely simple structures
