Moreover, due to the structural advantages of the prefabricated branch cable, the failure rate is relatively low. Therefore, in the long run, the maintenance and repair costs can be reduced. At the same time, the design of the prefabricated branch cable allows the cables to be efficiently distributed in a limited space, which is suitable for space-constrained scenarios such as high-rise buildings, subways, and tunnels. The branch design of the main trunk 113 and the branch trunk 114 in the flame-retardant prefabricated branch cable not only improves the installation efficiency and safety of the cable system but also provides convenience for the long-term stable operation and maintenance of the power system.
