Intelligent monitoring looped network cable for rail transit

The utility model discloses an intelligent monitoring looped network cable for rail transit. The intelligent monitoring looped network cable sequentially comprises a power transmission cable core, a non-magnetic armor layer and an environment-resistant sheath layer from inside to outside, the power transmission cable core sequentially comprises an insulating wire core, a metal wire shielding layerand a waterproof layer from inside to outside. The metal wire shielding layer comprises a monitoring optical fiber, a pressure-bearing metal wire and a metal shielding wire which are uniformly and sparsely wound on the outer peripheral surface of the insulating wire core. According to the utility model, the optical fiber is tightly laid on the outer peripheral surface of the insulating wire core,so that the operating parameters of the cable can be acquired and monitored in real time, and the functional requirements of cable service life estimation and cable fault pre-judgment are met. 本实用新型公开了一种轨道交通用智能监控环网电缆，由内至外依次包括
