Intensive undersea optical cable applicable to remote intelligent monitoring system

Abstract

An intensive undersea optical cable applicable to a remote intelligent monitoring system provided by the invention relates to an optical cable used in the undersea environment, pertaining to a field of monitoring and control technology. The intensive undersea optical cable combines application of an undersea high-low voltage power cable, an undersea communication cable and a remote intelligent monitoring system fiber sensing cable, and comprises undersea power transmission insulated cables, undersea communication cables and multi-layer metal protection sensing optic cables. A center gap and an external gap are formed after stranding of a plurality of the undersea power transmission insulated cables. The center gap has internal structure filling. The external gap is provided with the undersea communication cables and the multi-layer metal protection sensing optic cables. The external gap is further provided with cable core external structure filling. The common part is provided with an inner cladding layer. An inner buffer layer is provided outside the inner cladding layer. Outside the inner buffer layer are provided an anticorrosive metal singlet armored layer and an asphalt waterproof anti-corrosion layer. Outside the anticorrosive metal singlet armored layer is provided an external wrapping layer.

Description

technical field [0001] An intensive submarine optical cable suitable for a remote intelligent monitoring system of the present invention relates to the optical cable used in the submarine environment and the technical field of measurement and control.

[0002] With the development of submarine optical fiber cable and power cable production technology and the advancement of equipment technology, traditional submarine optical communication and power transmission submarine cables have gradually been combined or combined into one, which is commonly referred to as submarine photoelectric composite cables. It is directly laid on the seabed, and it also needs to have the anti-seepage, water pressure resistance, tensile, anti-corrosion, and anti-wear properties required by the original submarine cable and submarine optical cable, so as to meet the long-term use requirements of submarine cables, but such submarine cables It also cannot provide the remote unmanned monitoring function of cable temperature change and abnormal external force damage
