[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. It is defined as a wire made of one or more mutually insulated conductors and an outer insulating protective layer, which transmits electricity or information from one place to another. In order to ensure the security of data, people hope that after a fire occurs, there will be enough time to retrieve all data before the entire network is paralyzed, and transfer them to a safe place to minimize the possibility of data loss. Therefore, in the cable standards, there is also a type of fire protection standard, called the "line integrity" standard. Its goal is to keep the cable line unobstructed in the fire scene, so that power and information can still be transmitted normally. Therefore, cables that meet the series integrity requirements are also called fireproof cables, and fireproof cables need to be tested for their fireproof performance after they are produced.
