Abstract
The utility model relates to a seabed electric power composite optical cable, which is formed by that three or a plurality of insulated power cables are twisted together according to definite pitch, and simultaneously is twisted into one or more light unit (s) synchronously with small tension. The inside and outside peripheral clearance of the utility model is filled with oil, grease or factice for blocking water; the periphery of the utility model is wrapped with a polypropylene rope, an armored steel wire protective layer and two layers of polypropylene ropes, each layer of the polypropylene ropes and the armored steel wire is injected with asphalt, and the outermost layer is wrapped with a non-woven cloth. The utility model can be used for delivering electric power for facilities from a mainland to a sea island, a sea oil platform, etc., and at the same time can carry out modernized optical fiber communication. The utility model has the advantages of one cable with multiple purposes and exploration, laying and operation cost saving.
Description
Affiliated technical field
The utility model relates to a kind of seabed that is laid in provides electric power and modernized optical communication service simultaneously to the destination compound cable.
Background technology
Existing sea electric power cable and submarine optical fiber cable are used for transmitting electric power and the optical communication service between intercontinental, continent and island respectively separately.These cables are laid in the frequent main channel of passing ships, and the cable laying operation gigantic project is costly, and the duration be subjected to condition effect such as trend, weather, season, daily maintenances on duty such as also will going on patrol, watch from a height or a distance at run duration, efficient is not high.
Summary of the invention
In order to overcome the deficiency that existing sea electric power cable and submarine optical fiber cable lay the expense costliness of bringing, operation inconvenience on duty etc. respectively separately, the utility model provides a kind of subsea power composite cable, make it when marine facilities such as island and oil platform provide electric power, the multi-functional compound cable of modernized optical communication service can be provided again, with the attenuating expense, improve mixed economy and social benefit.
The technical scheme in the invention for solving the technical problem is: by 3 or thoroughly do away with the edge power cable more and twist together by certain pitch, twist one or more light unit synchronously with small tension receiving coil simultaneously, above-mentioned light unit is the welded stainless steel pipe that comprises fibre bundle, seamless metal pipe or nonmetallic pipe, pipe contains fibre bundle and fills the hydrophobic type greasy for preventing water of inhaling hydrogen, pipe is outer to extrude or the sheath of wrapped tygon or other suitable material, circumferential play is filled the oil that blocks water in stranded power cable and light unit, grease or ointment, at its peripheral wrapped rubber strap, the periphery bag cushion polypropylene rope of rubber strap pours into pitch simultaneously, stranded one deck of the periphery of cushion or multilayer armouring wire sheath also pour into pitch, the wrapped two layers of polypropylene rope of the periphery of armouring wire also pours into pitch, at the wrapped nonwoven fabrics of its outermost layer.
The beneficial effects of the utility model are when island and marine facility provide electric power, and modernized optical communication service can also be provided, and having saved construction greatly and having laid and operating cost, produce huge economic and social benefit.
