[0002] Prefabricated lines are cables with branches that are manufactured on an assembly line using a series of special production equipment within the factory according to the main and branch cable models, specifications, cross-sections, lengths and branch positions required by cable users. Pre-branched cables are cables that the factory prefabricates with branch lines according to user design drawings when producing trunk cables. They are a new technological product in recent years. Branch lines are pre-manufactured on trunk cables by the factory. The cross-sectional size and length of the branch lines are determined according to design requirements, which greatly shortens the construction period, significantly reduces material and construction costs, and further ensures the safety and reliability of power distribution.
[0003] When existing cable prefabricated wires are in use, their surface usually provides protection for the internal wire core through an insulating skin. However, when squeezed by objects with sharp end faces, the internal wire core is prone to breakage. For this reason, we propose a cable prefabricated wire with a protective structure.

[0028] In another embodiment, Figure 2 As shown, the connection reinforcement mechanism 4 includes a connection reinforcement steel wire rope 11 , and a connection reinforcement block 10 is fixedly connected to the outer surface of the connection reinforcement steel wire rope 11 .
[0029] The connection reinforcement blocks 10 can improve the compressive strength, and the connection reinforcement wire ropes 11 can restrict the connection reinforcement blocks 10 so that the connection reinforcement blocks 10 can be used stably.
[0030] In another embodiment, Figure 2 As shown, a fixing groove 12 and a first fixing slot 13 are formed on the outer surface of the first sleeve 3 .
[0031] The connection reinforcement block 10 can be stuck in the inner side of the fixing groove 12, and the connection reinforcement wire rope 11 can be stably stuck in the inner side of the first fixing groove 13, so that it can be stably installed and used.
