Abstract
The utility model provides a submarine fiber cable of corrosion resistance, core and a plurality of optic fibre are strengthened including the center, optic fibre surrounds the center of living and strengthens the core to it lives a plurality of optic fibre claddings to be provided with band A, the surface of a single optic fibre is provided with the waterproof layer, it has the cable filler to pack between band A and the optic fibre, band A's the outside has set gradually carbon coating, band B, the band B outside is provided with zinc -plated copper line armor, the outside cladding of zinc -plating copper line armor has corrugated steel pipe, corrugated steel pipe's the outside has set gradually HDPE inner sheath, anticorrosion iron wire armor and polyethylene oversheath, through being provided with tight multi -storied structure protection optic fibre to prevent that the optical cable is in seabed fracture and prevent the invasion of sea water.
Description
Technical field
The utility model relates to field of cables, particularly relates to the submarine optical fiber cable that a kind of corrosion resisting property is more excellent.
Background technology
Submarine optical fiber cable is by the wire of wrapped with insulation, be laid on seabed, in order to set up the wire transfer between country, optical cable laying is very large in the quantities in seabed, needs the cost costed a lot of money, and some seabed has a few km dark, this just requires that optical cable must tension and resistance to compression, prevents optical cable from rupturing suddenly, and also must prevent the intrusion of seawater in the seawater, therefore, the problem of raising submarine optical fiber cable tension, resistance to compression, corrosion resisting property seems particularly important.
Utility model content
For the deficiency of limited technical, the utility model provides a kind of corrosion proof submarine optical fiber cable, by the structural defence optical fiber of tight multilayer, to prevent optical cable in submarine rift and the intrusion preventing seawater.
In order to solve the problem, the utility model provides a kind of corrosion proof submarine optical fiber cable, include center strengthening core and some optical fiber, described optical fibre packages surrounds center strengthening core, and be provided with band A some optical fiber is enveloped, the outside surface of described single optical fiber is provided with water barrier, cable filling material is filled with between described band A and optical fiber, the outside of described band A is disposed with carbon coating, band B, described band B arranged outside has galvanized copper wire armouring, the outside of described galvanized copper wire armouring is coated with corrugated steel tube, the outside of described corrugated steel tube is disposed with tygon inner sheath, corrosion protection iron wire armoring and outer protective polyethylene cover.
Further improvement is: be provided with pure polyester thread body between described tygon inner sheath and corrosion protection iron wire armoring.
Further improvement is: be also provided with corrosion protection iron wire armoring B outside described corrosion protection iron wire armoring A, be provided with water blocking layer between described corrosion protection iron wire armoring A and corrosion protection iron wire armoring B.
Further improvement is: be filled with polypropylene wax in described corrosion protection iron wire armoring.
Further improvement is: described outer protective polyethylene cover outside is coated with one deck lime paste.
The beneficial effects of the utility model are: by being provided with the structural defence optical fiber of tight multilayer; to prevent optical cable in submarine rift and the intrusion preventing seawater; improve the resistance to compression of submarine optical fiber cable, tension and corrosion resisting property, decrease the cost that the later stage damages required maintenance.
