Abstract
The utility model belongs to the technical field of cables and relates to a 26/35KV photoelectric compound-type submarine cable. The cable is characterized in that a binding tape layer, a TPU plastic lining layer, a zinc-plated steel wire layer, and an outer sheath are sequentially arranged on the outer side of three cable main lines which lean on one another. An optical fiber unit is arranged in the center of a gap between every two adjacent cable main lines and the binding tape layer. Filler is arranged in a gap between the outer surface of each cable main line and the outer surface of the optical fiber unit, and the inner surface of the binding tape layer. Each of the cable main lines is formed by sequentially arranging a conductor shielding layer, an XLPE insulating layer, an insulated shielding layer, a semi-conductive water-resisting tape layer, a lead sleeve layer, an anti-corrosion layer, and a PE sheath layer from inside to outside on the outer surface of a water-resisting conductor. The water-resisting conductor is formed by intertwisting multiple strands of electrician oxygen-free copper wires, and water-swelling water-resisting powder is arranged in single-wire intertwising gaps among the adjacent electrician oxygen-free copper wires. The cable is advantaged in that the cable is good in conducting, corrosion-resisting, and water-resisting properties; the cable can perform optical fiber signal transmission at the same time; and the cable is applicable to submarine environments.
