This means that in the event of a fire or other high-temperature disaster, wires and cables may be rapidly damaged due to their inability to withstand high temperatures, leading to power system failure, increasing the difficulty of personnel evacuation, increasing the risk of fire spread, and potentially exacerbating property losses caused by fire. Therefore, in order to improve the safety and reliability of wires and cables in the event of a fire, it is necessary to develop and apply wire and cable products with fire resistance to reduce the impact of high-temperature disasters on wires and cables, ensure the stable operation of the power system, and reduce the potential losses caused by fire.
