Once the cable fails, it may cause the entire production line to stop, causing huge economic losses. For example, in the high-temperature, high-humidity and potentially fire-risk industrial environment of chemical industry, steel and other industries, cables have to withstand harsh working conditions to ensure the continuous and stable supply of power. In the field of construction engineering, especially in large commercial buildings, high-rise buildings and underground facilities, the use of cables is huge and dense. Once a fire occurs, if the cable does not have fire resistance, it will not only burn itself, but also may become a channel for the spread of fire, exacerbating the harm of the fire.
