The invention discloses a heat dissipation type power cable. A cable core comprises a core conductor; the surface of the core conductor is sequentially provided with an insulating paint layer, an anti-corrosive paint layer, a rubber insulation layer and a first pressure-proof heat dissipation layer from inside to outside; the periphery of the cable core is sequentially coated with a glass fiber mesh layer, a non-woven fabric layer, a shielding layer, a second pressure-proof heat dissipation layer and an outer sheath layer; a filler is filled between the cable core and the glass fiber mesh layer; and each of the first pressure-proof heat dissipation layer and the second pressure-proof heat dissipation layer comprises a first metal layer and a second metal layer, and a plurality of support ribs which are distributed at equal intervals are arranged between the first metal layer and the second metal layer. The heat dissipation type power cable provided by the invention has a heat dissipation structure, so that the heat generated when the cable works in a high-temperature environment can be reduced in time, aging and breaking of the insulation layer caused by too high internal temperature of the cable can be avoided, the service life of the power cable can be prolonged, and the transmitting capacity of the cable can also be improved.
