1. High-Temperature Resistance: The materials used in high-temperature cables must maintain their electrical and mechanical properties under high-temperature environments and possess excellent heat resistance, flame retardancy, and oxidation resistance.
2. Corrosion and Erosion Resistance: High-temperature environments not only require withstanding high temperatures but also subject to corrosion and oxidation. Therefore, high-temperature cables must have strong corrosion and erosion resistance.
3. Low Energy Consumption: High-temperature cables should have low resistance, reactance, and capacitance to ensure low energy consumption and reliable operation under high voltage.
4. Interference Immunity: Electromagnetic interference is common in high-temperature environments. Therefore, high-temperature cables must have excellent interference immunity to ensure stable signal transmission.
