The invention discloses an anti-corrosion, acid and alkali resistant watertight cable and a preparation method thereof, and relates to the technical field of cables. The gaps between are filled with water-blocking glue to form an intermediate water-blocking layer, a plurality of the conductive central units are covered with a polyester layer, and a metal shielding layer and an outer sheath are sequentially arranged outside the polyester layer. An outer water blocking layer is arranged between the outer sheath and the metal shielding layer. The anti-corrosion, acid and alkali-resistant watertight cable of the present invention is provided with multi-level water blocking layers on the structure, and the water blocking layers are tightly filled with good water blocking effect. Corrosion, acid and alkali resistance are good, and it can be used in deep seawater environment. |
