Cables include composite cables. Composite cables are suitable for use as transmission lines in broadband access network systems. They are a new type of access method that integrates optical fiber and power transmission copper wire.

[0003] At present, related composite cables are easily affected by high temperature and burn due to the lack of multiple protective structures, and are easily broken and separated by external forces, which affects the service life of the cables. Utility Model Content

[0007] The insulating layer can provide insulation and waterproof protection for the wires. The inner protective layer is made of silicone material, which can fill the gaps between the wires and provide further protection to prevent the wires from being deformed by pressure and external force. The protective layer has good anti-corrosion and anti-aging effects, which can prevent the cables from being corroded and damaged by the environment, and extend the service life of the cables. The reinforcement sheet has a certain degree of flexibility and high strength, which can prevent the cables from being broken and separated by external shear force. The flame retardant layer can enhance the high temperature resistance and flame retardant effect of the cable.

[0008] Preferably, a decorative ring is arranged on the periphery of the flame retardant layer, and the decorative ring is made of an organic numerical material.

[0009] The flame retardant layer can be decorated by the decorative ring, and the eye-catching effect of the flame retardant layer is improved, making it easier for workers to observe the position of the cable.

[0010] Preferably, the flame retardant layer is fixedly connected with connecting wires inside, and six connecting wires are provided.

[0011] The flame retardant layer can be reinforced by the connecting wire to prevent the possibility of the flame retardant layer breaking and separating.

[0012] Preferably, a cavity is provided inside the inner protective layer, and the cavity is circular.

[0013] Other wires can be inserted into the cavity for connection, so that the cable can add wires as needed.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] The protective layer is made of anti-corrosion polyethylene material, which has good anti-corrosion and anti-aging effects, preventing the cable from being corroded and damaged by the environment, thus extending the service life of the cable. The reinforcement plate is made of flexible iron material, which has certain flexibility and high strength, preventing the cable from being broken and separated by external shear force. The flame retardant layer is made of flame retardant polyolefin material, which can improve the high temperature resistance and flame retardant effect of the cable, avoid safety accidents caused by cable burning, and effectively improve the safety of the cable.
