            Special cables are different from ordinary cables. Special cables can be used in special occasions, and their functions also have particularities, such as high temperature resistance, strong acid and alkali resistance, termite prevention and so on. Among them, high temperature resistant wires and cables are mainly used in energy development, steel, aerospace, oil exploitation and metal smelting and other fields. Low inductance cable has good heat dissipation effect. It not only has large cooling water flow, but also does not block and limit current. Low noise cables are mainly used in medical, industrial, national defense and other fields requiring small signal measurement, and can detect bass. In addition, there are functional wires and cables and new green environmental protection cables.
            The development direction of special cable is diversified. Large military enterprises shoulder the task of national modern equipment and high-tech equipment. The demand for light weight and high temperature resistant cables is particularly large. The main cables used in construction are double-layer flame retardant, high temperature resistant and low smoke, halogen-free environmentally friendly cables, mainly to prevent fire hazards and unsafe accidents. With the increasing energy shortage in the mainland, the exploitation of oil and natural gas began to turn to the ocean, thus increasing the demand for integrated cables used in the ocean field. With the vigorous development of civil aviation in China, Boeing aircraft use more cables and cables, most of which use light weight, small size, high temperature resistant irradiation cross-linking or silane cross-linking wires and cables. Among many types of special cables, especially high temperature superconducting transmission cables, the market prospects are broad. High-temperature cables, with their super vitality, are used in various occasions of short-distance transmission of large currents, which are in short supply.
            Special cable will surely be on the market in the next few years, and it will play an increasingly important role in social development and progress.
