Fire-resistant cables refer to cables that can maintain safe operation for a certain period of time under flame burning conditions. China's national standard GB12666.6 (such as IEC331) divides fire resistance testing into two levels: A and B. The A-level flame temperature is 950~1000 ℃, with a continuous fire supply time of 90 minutes, and the B-level flame temperature is 750~800 ℃, with a continuous fire supply time of 90 minutes. Throughout the entire test period, the sample should withstand the rated voltage value specified by the product. Fire-resistant cables are widely used in high-rise buildings, subways, underground streets, large power stations, and important industrial and mining enterprises related to fire safety and fire rescue, such as power supply lines and control lines for emergency facilities such as fire equipment and emergency guide lights
