The invention provides a cable and a charging pile, relates to the technical field of cables, and aims to solve the technical problem that an existing cable is poor in heat dissipation effect. The cable comprises a sheath tube, a cooling tube and a cable core. The cooling pipe is arranged in the sheath pipe in a penetrating manner, and a cooling channel for cooling liquid to circulate is arranged in the cooling pipe; the number of the cable core is at least one, and the cable core is arranged in the sheath pipe in a penetrating mode and located in a cavity between the cooling pipe and the sheath pipe. A communicating hole is formed in the cooling pipe and forms circulation of cooling liquid between the cooling channel and the cavity. The cable disclosed by the invention has a relatively good heat dissipation effect.
