Embodiment Construction

[0030] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0031] According to an embodiment of the present invention, a photoelectric composite submarine cable is provided. Such as figure 1 As shown, this embodiment includes an optoelectronic composite assembly arranged in the axial direction, a double-layered axial double-layered positive water layer 10 wrapped around the periphery of the photoelectric composite The armor layer 12 is sleeved on the outer periphery of the inner lining layer 11 , and the outer jacket layer 13 is axially sleeved on the outer periphery of the armor layer 12 .

[0032] Wherein, the above-mentioned armor layer 12 can be galvanized steel wire, and the outer surface of the galvanized steel wire ...

Abstract

The invention discloses a photoelectric composite submarine cable, which comprises a photoelectric composite module which is axially arranged, two waterproof layers which are axially overlapped on the periphery of the photoelectric composite module, a liner layer which is axially sleeved on the periphery of the waterproof layer, an armoring layer which is axially sleeved outside the liner layer and an outer coat layer which is axially sleeved outside the armoring layer. The photoelectric composite submarine cable can overcome the weaknesses of the prior art that the waterproof performance is poor, the corrosion resistance is poor, the tensile resistance is poor, the cost is high, the installation and pavement difficulty is large and the like, and has the advantages that the waterproof performance is good, the corrosion resistance is good, the tensile resistance is good, the cost is low, and the difficulty in installation and pavement is small.

Description

technical field [0001] The present invention relates to cables, in particular to a photoelectric composite submarine cable. Background technique [0002] With the continuous enhancement of my country's comprehensive national strength, the vigorous promotion of marine development and the needs of national defense construction, at the same time, in order to improve the environment, improve the quality of production and life of the coastal people, the demand for electricity and communications continues to increase. The ultra-high voltage submarine power-optical communication composite cable provides a broad market prospect. In particular, new oil and gas fields are constantly being discovered in my country's shallow seas, such as Bohai Bay, the eastern and western parts of the South China Sea, and the proved recoverable oil and natural gas reserves are increasing. Therefore, in recent years, the CNOOC system will require a large number of submarine power cables, submarine photoe...
