I. The impact of high-temperature environments on cables In high-temperature environments, the electrical properties of cables are affected. Specifically, high temperatures reduce the resistivity of cables, increase their conductivity, and cause a drop in voltage ； At the same time, high temperatures can also cause the insulation material of cables to age and fail, increasing the cable’s failure rate and safety risks. Furthermore, in high-temperature environments, the load-carrying capacity of cables decreases, making them prone to problems such as power outages and short circuits, which affect the proper operation and safe use of cable systems. II. The impact of low-temperature environments on cables In low-temperature environments, the electrical properties of cables are also affected. Low temperatures increase the resistivity of cables, reduce their conductivity, and cause the voltage across the cables to rise ； At the same time, low temperatures can also make the insulation material of cables brittle and harden it, making it more susceptible to damage and increasing the cable’s failure rate and safety risks. Additionally, in low-temperature environments, the mechanical properties of cables are also affected; this makes them prone to comprehensive failures, thereby impacting the normal operation of cable systems. III. Measures to control ambient temperature To ensure the proper operation and safe use of cable systems, effective measures must be taken to control the ambient temperature. Firstly, when designing a cable system, appropriate selection and wiring should be carried out based on the ambient temperature. When installing the cables, it is necessary to avoid using materials that come into contact with surfaces at high or low temperatures, and to ensure that there is sufficient distance between the cables and their surrounding environment. During cable maintenance, it is also necessary to regularly check the electrical performance and insulation condition of the cables, so as to identify and resolve any existing problems promptly and ensure the proper operation of the cable system. In summary, ambient temperature is an important factor affecting the performance and lifespan of cables. During the design, installation, and maintenance of cables, environmental temperature factors must be taken into account, and effective measures must be adopted to control temperature in order to ensure the proper operation and safe use of the cable system.
