[0002] Power cables are cables used to transmit and distribute electrical energy. They are commonly used in urban underground power grids, power plant lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas. The proportion of cables in power lines is gradually increasing. Power cables are cable products used to transmit and distribute high-power electrical energy in the main lines of the power system, including power cables of various voltage levels from 1 to 400kV and above, and various types of insulation.

[0003] Currently available impact-resistant and flame-retardant cables on the market are not perfect when users need to perform auxiliary positioning and splicing between multiple cables, and their effect is not good enough when users need to use fire-resistant cables to resist impact, thus affecting the use of fire-resistant cables.
