The utility model discloses an anti-corrosion and dampproof cross linked polyethylene insulated power cable. The anti-corrosion and dampproof cross linked polyethylene insulated power cable comprises an outer cladding layer and at least one insulated cable core arranged in the outer cladding layer. An inflaming retarding wrapping tape layer, a longitudinal waterproof layer, an isolating layer, an armor layer, inflaming retarding wrapping tape and a jacket layer are sequentially arranged inside the outer cladding layer from inside to outside in a wrapping mode. Each insulated cable core comprises conductors, an inner shielding layer, an insulating layer, an outer shielding layer and a metal shielding layer, wherein the inner shielding layer, the insulating layer, the outer shielding layer and the metal shielding layer are sequentially arranged on the conductors from inside to outside in a wrapping mode, and the inner shielding layer, the insulating layer and the outer shielding layer are combined in a three-layer-co-extrusion mode. By means of the anti-corrosion and dampproof cross linked polyethylene insulated power cable, inflaming retarding is achieved, and the anti-corrosion effect and the dampproof effect are achieved.
