Abstract
The invention provides a three-core 500kV cross-linked polyethylene insulated optical fiber composite submarine cable. The three-core 500kV cross-linked polyethylene insulated optical fiber composite submarine cable comprises three cable cores, a protection unit, filling units and optical fiber units, the three cable cores are all located in the protection unit, the three cable cores are uniformly distributed in the circumferential direction of the protection unit at intervals, and gaps for accommodating the filling units and the optical fiber units are formed between the cable cores and between the protection unit and the cable cores; the interior of the first filling unit is provided with an installation space for embedding the optical fiber unit, the axial direction of the installation space is consistent with the axial direction of the submarine cable, and the cross section of the installation space is circular. The three-core 500kV cross-linked polyethylene insulated optical fiber composite submarine cable is low in manufacturing cost, and the optical fiber units are not easy to damage.
Description
technical field [0001] The present application relates to the technical field of submarine cables, in particular to a three-core 500kV XLPE insulated optical fiber composite submarine cable. Background technique [0002] Submarine cables are wires wrapped with insulating materials and laid under the seabed and rivers for telecommunication transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Submarine communication cables are mainly used for communication services, and submarine power cables are mainly used for underwater transmission of high-power electric energy. [0003] The withstand voltage of the current high-voltage submarine cable is generally 220kV, and generally includes a cable core, an optical fiber unit and a protection unit. The cable core is a single-core structure, and the protection unit is coated on the outside of the cable core. Or the optical fiber unit is arranged in the protection unit, and the prote...
