Abstract
The invention discloses a high strength buoyant cable. The centre of the cable is provided with a floating element. The outside of the floating element is provided with a conductor which contains a fiber bundle reinforced core therein. A sealing layer is provided between the conductor and the floating element. The outside of the conductor is sequentially clad with an internal sheath and an exterior sheath, wherein an insulating layer is provided between the internal sheath and the exterior sheath, and the insulating layer is a bilayer structure consisting of an internal insulating layer and an exterior insulating layer. The central position, in the wall thickness direction, of the exterior sheath is provided with two high-tensile steel wires that are parallel to each other and arranged along the longitudinal direction of the cable. As compared with the existing art, the inventive cable's conductor employs a stranded conductor with a larger section and meanwhile in part employs an insulated conductor in order to ensure the feasibility and reliability of multipolar power supply, whilst also can greatly enhance the strength and overall performance of the cable by means of adding fiber bundles to optimize the stranded structure design of the conductor as well as providing a tensile means consisting of two parallel high-tensile steel wires at the central position, in the wall thickness direction, of the sheath.
Description
Technical field
The invention belongs to field of cable technology, be specifically related to a kind of high strength buoyant cable.
Background technology
High strength buoyant cable is the critical function element realizing transmitting between naval vessel and the water surface or underwater operation parts dynamic power, and it is related to functional realiey and the safety guarantee of power consumption equipment in naval vessel body and the water surface or water.Floating element determines that can cable swim in the key element of the water surface, it select the float function index not only determining cable, and farthest determine the manufacturing process of buoyant cable.Floating element generally selected special timber and hollow metal part in the past, and not only cost is very high, processed also pretty troublesome.Consider from normal cable method for designing, conductor at center, although conductor structure is therefore more stable, because floating element thermal resistance is comparatively large, should certainly will causes overall thermal resistance large, cause current-carrying capacity of cable to reduce, be unfavorable for very much the big current transmission of cable.Meanwhile, the intensity of most of buoyant cable is poor, thus have impact on useful life.
Summary of the invention
The object of the present invention is to provide a kind of high strength buoyant cable of new construction, it not only can meet the designing requirement of float function completely, and structure is simple, and intensity is high, thus solves the problem.
For realizing this purpose, technical scheme of the present invention is: a kind of high strength buoyant cable, described cable center is equipped with floating element, conductor is provided with outside described floating element, containing fibre bundle strengthening core in described conductor, sealant is provided with between described conductor and floating element, the described outer inner sheath be coated with successively outside conductor, oversheath, described inner sheath, insulating barrier is provided with between oversheath, described insulating barrier is the double-decker be made up of inner insulating layer and external insulation layer, described oversheath wall thickness middle position is provided with two and is parallel to each other and the high-tensile steel wires arranged along cable longitudinal direction.
As preferably, described conductor by the identical radical of bilayer, twist and form to contrary conductor strand.
As preferably, described oversheath is modification high-density polyethylene sheath.
As preferably, described inner sheath is halogen polyolefin jacket.
As preferably, described thickness of insulating layer is 0.23 ~ 0.50mm.
As preferably, inside described inner sheath, be also provided with a circle braided steel wire webbed skeleton resistance to compression layer.
Compared with prior art, the conductor of cable of the present invention adopts larger cross-section stranded conductor, and part adopts insulated electric conductor, to ensure the feasibility that multipole is powered and reliability simultaneously.Leading body is selected double-deck identical radical, is twisted to contrary stranded conductor structure, and because its stranded rear external diameter is close, Haul Rate is identical, and strand is on the contrary, and therefore this structure can not produce torsion in manufacture with in using.Consider that its radical is less, increasing insulation can contribute to some extent to whole cable buoyancy, and guarantees the factors such as its reliability, and guidance body is designed to insulated electric conductor.By adding fibre bundle, design being optimized to conductor strand structure, greatly improving its flexibility, improving the adaptability of conductor.Arrange in the wall thickness central authorities of sheath and form tension member by the high-tensile steel wires of two parallel placements, contribute to promoting cable strength, can play a protective role to cable when cable bears larger pulling force.Meanwhile, inside described inner sheath, be provided with a circle braided steel wire webbed skeleton resistance to compression layer, improve the tensile and compressive property of cable further.
