Description
Technical field
The utility model relates to cable technology field, is exactly specifically a kind of multicore, phase-splitting sheath optical fiber composite submarine cable.
Background technology
The annual submarine cable of China, pipe laying length have several thousand kilometers, and submarine cable accounts for 10% ~ 15% left and right of whole laying amount. the Internet era of entering along with the development of national economy, island construction, Islands Exploitation, deep-sea oil gas energy extraction will continue to carry out, and extra large cable is being played the part of indispensable key player in these projects, the universal rapidly of internet constantly increases mass data transmission requirement, and the compound extra large cable of optical fiber has been born 90% communication service. in the time developing small-sized and marginal field, conventionally rely on original macrotype platform, what the production platform of small-sized marginal field was built is very simple and easy, even production platform is built up to nobody that only have a small amount of critical process flow sheet equipment and garrison simple platform, electric submersible pump equipment on platform, navigation system, signal and communication and blind controller system etc. are by original macrotype platform remote control management, according to proved reserves, the small-sized field produces time limit is short, be generally 5 ~ 6 years, conventional power supply plan can choice for use cable of electric submersible pump or the product such as conventional submarine cable, but there is technology, the factors restriction of price and construction.
As mentioned above the stretch-proof ability of cable of electric submersible pump is poor, lays separately difficulty very large; Anti-seawater corrosion ability is poor, and the protective layer corrosion in the salt marsh environment such as seawater of its surperficial galvanized iron sheet comes off, and mechanical performance reduces, and the fault rate that therefore phenomenon causes will increase greatly. Simultaneously be only 2 years the service life of cable of electric submersible pump, can not meet the requirement of the oil gas field production and application time limit, again lays problems such as relating to during construction equipment facility, the moving demobilization of workmen and transformation oil field stopping production, safeguard and use cost too high.
And standard sea cable structure only can be used for 100 meters of depth of waters with interior marine site, electric property, water resistance to extra large cable when deep-sea oil, gas well exploitation all have higher structural requirement. At present conventional mesolow sea cable structure comprises three power cables and a communications optical cable, and the extra large cable of this structure has the following disadvantages:
1, Meteorological is too high, the submarine cable electric power transfer of above-mentioned standard is realized by three power cables, be 30 years the projected life of cable, the extra large cable that each simple platform needs many so independent routes to lay could meet the Multifunctional conveying demand of installations and facilities on simple platform, but consuming time owing to laying the work capacity restriction of extra large cable working ship and repeating to spread cable operation, the reason such as expend, cause engineering overall work amount large, claim for eot, engineering input cost is high, independent route is laid and is needed accessory kit terminal simultaneously, the quantity of junction box and J pipe bend protection and simple platform floor space increase, this also will increase exploitation engineering cost undoubtedly.
2, the electrical connection between electric-cable core is bad, metal screen layer lead sheath uses pe sheath outward, for the big-length sea cable of two ends interconnection ground connection, between three-phase metallic lead sheath, induced electromotive force can not be cancelled out each other, between the plumbous cover of non-like this interconnection section and armor, have potential difference, thereby superpotential existence will cause pe sheath electrical breakdown to affect line security operation.
3, the optical cable unit of extra large cable is to be arranged in the gap of power cable, the PP softer with filling employing material around restricts, while producing stranding, the roundness of cable core is not high, optical cable unit can not well be fixed, while laying at deep-sea, marine site stormy waves is large simultaneously, tidal fluctuations is continuous, high to the requirement of optical cable unit tensile property, the easily fracture in the time laying of this structured light unit.
Summary of the invention
The purpose of this utility model is to provide a kind of multicore, phase-splitting sheath optical fiber composite submarine cable, and this cable has water proofing property, corrosion resistance, good insulating, and the life-span is long, and reliability is high, can effectively reduce construction working amount, reduces engineering input cost.
