Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes a kind of composite power cable peculiar to vessel, while guarantee power cable roundness, reducing the production cost of power cable, improve the useful life of power cable.
The one composite power cable peculiar to vessel that the present invention proposes, comprises center wire and the outer cable of X root, 3≤X≤6; Center wire comprises center conductor group and is coated on the first fire-retardant lapping layer, the first screen and the inner restrictive coating outside center conductor group successively, and center conductor group comprises the mutually stranded center conductor of Y root, Y=X; Outer cable comprises outer conductor group and is arranged on the U-shaped bar outside outer conductor group, and outer conductor group comprises the Z root outer conductor be positioned on same circumference, 1≤Z≤3, and each outer conductor all offsets with U-shaped bar madial wall, and two outer conductors of arbitrary neighborhood offset; The outer cable of X root is distributed on outside center wire, outer cable is between arbitrary neighborhood two center conductors, the exterior bottom of U-shaped bar is bonded on center wire, at outer conductor outer coated second fire-retardant band lapping layer, secondary shielding layer and external sheath layer successively, all fire-retardant band lapping layer offsets each outer conductor with second.
Preferably, center conductor, outer conductor are formed by conductor thread core and fire-resistant isinglass belt lapping layer, elastomer cloth lapping layer and the insulating barrier be coated on successively outside conductor thread core.
Preferably, U-shaped strip adoption elastic metal sheet is made, and U-shaped bar side height is less than or equal to the diameter length of outer conductor.
Preferably, U-shaped strip adoption elastoplast is made, and U-shaped bar side height is less than the diameter length of outer conductor.
Preferably, the madial wall of U-shaped bar bottom surface and lateral wall are equipped with thermal insulation layer.
One provided by the invention composite power cable peculiar to vessel, when in cable core, number of conductors is less, outer cable adopts U-shaped bar to be limited on same circumference by Z root outer conductor, reduce the cross-section volume of outer cable, do not need between outer conductor, to fill filler or fill filler less to ensure its roundness, reduce production cost, and outer cable adopts U-shaped bar to improve the tensile strength of composite power cable, the useful life extending cable is low.
Accompanying drawing explanation
