Particularly, as line safety performance is more and more emphasized, statistics shows that the proportion of the line safety performance caused by electrical faults in a fire accident is more than sixty percent. When a fire disaster occurs, how to ensure the integrity of a power line ensures that fire-fighting equipment such as a fire elevator and a fire pump can keep normal operation within a certain time, strives for rescue time as much as possible, and has great significance. Therefore, the high-temperature resistance and fire resistance of the cable are improved, and the running time of the cable in the fire extreme environment is increased, which is very important.

On the other hand, in practical production and application, the cable with a fire-resistant function cannot well solve the phase splitting problem of each core, and for convenience of construction and installation, a mode of extruding and wrapping cross-linked polyethylene with colors outside a fire-resistant layer or adding a color band outside a conductor is usually adopted, so that the cross-linked polyethylene and the color band do not have high-temperature resistance and can be rapidly melted in a fire disaster to damage the cable structure. Therefore, how to manufacture the high-temperature-resistant cable with the phase splitting mark is also important for improving the convenience of cable construction and installation and ensuring the high-temperature-resistant and fire-resistant performance of the cable.
