Abstract

The invention discloses a large cross section submarine optical cable. The large cross section submarine optical cable comprises an optical cable core and an optical cable outer jacket, wherein the core comprises a stainless steel light unit, an inner armored steel wire, a copper pipe, a copper wire, a water blocking material and shielding layer and an insulation sheath, the inner armored steel wire is twisted on the stainless steel light unit and is then wrapped in the copper pipe, the copper wire is externally twisted the copper pipe, the copper wire is wrapped in the water blocking material and shielding layer, the water blocking material and shielding layer is externally wrapped in the insulation sheath, the outer jacket sequentially comprises an outer armored steel wire, asphalt and a polypropylene rope from inside to outside, the outer armored steel wire is twisted on the insulation sheath, the outer armored steel wire is wrapped in the polypropylene rope, and the asphalt is filled between the insulation sheath and the polypropylene rope. The optical cable is advantaged in that the structure is reasonable, corrosion of the steel wire can be effectively prevented, service life in sea water can be prolonged, integrity, mechanical performance and physical performance of the cable are effectively protected, damage caused by boat anchor dragging and offshore waters excavation can be prevented, the polypropylene rope has strong environment adaptability, and service life of the cable used in the sea water can be guaranteed.

Description

technical field [0001] The invention relates to a large-section submarine optical cable. Background technique [0002] At present, the electrical performance of the submarine optical cables used in domestic occasions with high requirements for marine power and signal transmission is not ideal, and the use of the now common submarine photoelectric composite cables has improved electrical performance, but the production cost Then it will be doubled several times, and it is not suitable for large-length production. At present, China's economy has developed into an export-oriented economy that is highly dependent on the ocean, and its dependence on marine resources and space has increased significantly. The maritime rights and interests outside the jurisdictional sea area also need to be continuously maintained and expanded. Submarine optical cables are the backbone. It has an irreplaceable role, and the new large-section submarine optical cable has improved the performance of ...
