General electrical wires and cables use plastic and rubber as insulation sheaths. These materials are conventional engineering materials, readily available, suitable for large-scale production, and relatively inexpensive. However, for specialized industries such as petrochemicals, steel, aerospace, shipbuilding, military, pharmaceuticals, food, plastics machinery, and boilers-industries involving heat and high temperatures-wires and cables capable of withstanding significantly higher temperatures are required. Ordinary wires and cables are clearly unsuitable; high-temperature resistant cables are necessary to ensure the safe operation of power and signals.
With my country's rapid economic development, the demand for high-temperature cables in specialized industries has entered a phase of rapid growth. The demand for heat-resistant and high-temperature cables is increasing at a rate of 20% annually. As a crucial component of specialized cables, high-temperature cables possess strong vitality and are in high demand, with supply falling short of demand. my country imports approximately 2 billion yuan worth of high-temperature cables annually for domestic construction.
