Safe power environment-friendly cable capable of rapidly dissipating heat

The invention relates to the field of cables, the invention discloses a safe power environment-friendly cable capable of rapidly dissipating heat. The cable solves the problem that the cable is on fire due to the fact that the temperature of the cable is too high, and comprises a plurality of cable cores and a shielding layer jointly wrapping the outer sides of the cable cores, a heat dissipationlayer set is arranged at the side, far from the cable cores, of the shielding layer, and an insulating layer and a protective sleeve are sequentially stacked and wrapped at the side, far from the shielding layer, of the heat dissipation layer set from inside to outside; the heat dissipation layer set comprises a first heat conduction layer and a second heat conduction layer which are arranged separately; the first heat conduction layer wraps the side, away from the cable core, of the shielding layer, a plurality of first cooling fins are arranged between the first heat conduction layer and thesecond heat conduction la
