Composite cable suitable for smart grid

The utility model discloses a composite cable suitable for a smart grid. The composite cable comprises a power core cable, an optical fiber core cable, concentric conductors for shielding, and a master sheath. The power core cable and the optical fiber core cable are gathered onto the central axis of the whole cable together coaxially through a wrapping tape. The outer edge of the wrapping tape is provided with a circumferential inner protective layer. The concentric conductors for shielding are distributed on the outer diameter of the inner protective layer in a planet manner and clad inside the master sheath through a copper strip. According to the utility model, comprehensive functions, such as the optical fiber communication function, the cable communication function, the power transmission function, etc., are integrated into the composite cable, the network construction cost is reduced, the composite cable is a 'multiple network integration' product for realizing the highest price cost performance, the multiple wiring operation is avoided, costs, such as the construction cost, the network construction cost, etc., can be effectively reduced, the advantage of good mechanical performance (such as, the shock resistance performance and good test pressure resistance performance) is realized, the advantage of good adaptive capacity to environment is realized, and the operation temperature of the optical fiber core cable and the operation temperature of the power cable are compatible with each other for a long time.
