Cable cooling system

The invention discloses a cable cooling system which structurally comprises a circulating water tank, a supporting table, a thermometer, a water pressure gauge and a cooling mechanism, the circulating water tank is fixedly installed at the bottom of the supporting table, and the cooling mechanism is installed on the upper end face of the supporting table; wind energy is generated through rotation of a draught fan, the wind energy is conducted into a branch guide ring through an air guide pipe and finally sprayed out from the interiors of eight nozzles on the inner side of the branch guide ring, an electromagnetic piece conducts repeated magnetic attraction on a sliding shaft, and a wiping plate conducts repeated annular sliding in a sliding groove; according to the cable insulation protection layer cleaning device, the wiping plate is arranged in the box body, it is ensured that dust adsorbed on the outer side surface of a cable insulation protection layer is effectively wiped away by the wiping plate, the te
