In recent years, with the development of social economy, the power and telecommunication industries have penetrated into daily life, and cables are widely used as carriers of signal transmission. Cables are generally rope-like cables made by stranding several or groups of conductors (at least two in each group), each group being insulated from each other and often twisted around a center, the entire outer surface being coated with a highly insulating coating. The cable has the characteristics of internal electrification and external insulation. The cable includes power cable, control cable, compensation cable, shielding cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resistant cable, marine cable, mining cable, aluminum alloy cable and the like. Existing wire and cable have limited impact resistance. When the electric wire or cable is used in a severe environment or is carried, the electric wire or cable is more or less impacted by external machinery, especially when a fire occurs, the electric wire or cable may be impacted by external impacts such as spraying of stones, wood boards, steel plates or fire-fighting water, and in such a case, the integrity of the outer sheath of the electric wire or cable is difficult to be ensured, so that the work of the internal circuit of the electric wire or cable is affected.
