At present, the concept of environmental protection is vigorously advocated worldwide, and the importance of environmental protection is increasingly valued by all countries. Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. Fire-resistant cable refers to a cable that can maintain safe operation for a certain period of time under the condition of flame burning. Fire-resistant cables are widely used in high-rise buildings, subways, underground streets, large power stations and important industrial and mining enterprises and other places related to fire safety and firefighting and lifesaving, such as power supply lines and control lines for emergency facilities such as fire-fighting equipment and emergency guide lights.
