Abstract

The utility model discloses an offshore buoyant cable. The offshore buoyant cable mainly comprises a buoyant linking rope, a buoyant element coated on the buoyant linking rope, a sealing layer coated on the outer side of the buoyant element, a group of main conductors stranded on the outer side of the sealing layer, an inner sheath coated on the outer side of the main conductor, a group of auxiliary conductors wound on the inner sheath and a cable protection layer extruded on the outer side of the auxiliary conductor. The main conductor utilizes the structural form of a stranded conductor with the same number of double layers and opposite stranding directions, and the auxiliary conductor is formed by a plurality of conductors and insulating layers coated outside the conductor. By the offshore buoyant cable, relevant technical requirements on transmission capacity and power supply mode are met, cables are prevented from rotating in the manufacturing and using process, and bearing and floating are provided simultaneously.

Description

A kind of floating marine cable
Technical field
The utility model belongs to the power cable field, is specifically related to a kind of floating marine cable.
Background technology
At present, the design of conductor mainly requires to carry out according to correlation techniques such as the transmission capacity of cable and supply power modes.The requirement that the conductor of floating marine cable will reach: the one, big electric current, low voltage power supply; The 2nd, for guaranteeing the bulk supply requirement, voltage drop is little; The 3rd, multi-electrode uses; And the floating marine cable conductor of ordinary construction form can not satisfy above three requirements simultaneously, so, need a kind of special floating marine cable conductor structural that the deficiency that present floating marine construction of cable form exists is remedied.
Use about stranded conductor; Because leading body adopts non-central formula stranded; Thereby exist in using because stranded reversing of causing by common cable armouring mode, adopted single-layer stranding; Then this rotation certainly leads in manufacturing and use, must improve construction of cable form commonly used at present in order to prevent cable rotation in manufacturing and use.
Buoyant cable pulls use in ship navigation, its pulling force that bears is very high, and requiring working pulling force is 2500kg, and pull-off force is 5000kg.Usually adopt the independent lotus element that holds, like materials such as steel wire, aramid fibers, but so; Cable weight certainly will increase, and floating index is also influenced, in addition; No matter adopt steel wire, aramid fiber or high strength macromolecular material; Consider and hold lotus element and two kinds of elasticity modulus of materials volumes of conductor difference, stressed inconsistent in the time of will causing cable to bear pulling force, can exert an influence.
In sum: the deficiency of floating marine cable conductor existence at present: the one, can not satisfy correlation technique requirements such as transmission capacity and supply power mode simultaneously; The 2nd, cable rotates in manufacturing and use; The 3rd, holding lotus and flotation property can not possess simultaneously.
The utility model content
The purpose of the utility model provides and a kind ofly can satisfy correlation technique requirements such as transmission capacity and supply power mode simultaneously, prevent cable make and use in rotate, and hold the floating marine cable that lotus and flotation property possess simultaneously.
The described a kind of floating marine cable of the utility model with conductor structure; Comprise floating chain splicing, be coated on the floating element on the floating chain splicing, be coated on the sealant in the floating element outside; Be stranded in one group of leading body in the sealant outside; Be wrapped in the inner sheath in the leading body outside, teach body and be extruded in the cable covering of teaching external side for one group that is wrapped on the inner sheath.
Described leading body adopts double-deck identical radical, and strand is to opposite stranded conductor version.
Described guidance body is by several conductors and be coated on the outer insulating barrier of conductor and constitute.
The beneficial effect of the utility model is:
1, the stranded conductor of cable conductor employing larger cross-section is as leading body; Solve the floating marine cable conductor and can not satisfy the problem that correlation techniques such as transmission and supply power mode require simultaneously; And increase the guidance body structure of giving less galvanic electrode transmission current, with feasibility and the reliability that guarantees multipole power supply.
2, leading body adopts double-deck identical radical; Strand has solved the problem that buoyant cable rotates to opposite stranded conductor structure in manufacturing and use, calculate through actual measurement; Because its stranded back external diameter is approaching; Haul Rate is identical, and strand is on the contrary, therefore this structure make and use in can not produce and reverse.
3, the utility model adopts the version of comprehensive conductor; Promptly as transmission conductor again as holding the lotus element; Solved the problem that lotus and flotation property can not possess simultaneously of holding, through actual test, this structural cable all reaches requirement and nargin is arranged at working pulling force and pull-off force.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The described a kind of floating marine cable with conductor structure of the utility model comprises the floating core chain splicing 1 of cable center, coats floating element 2 around it; The floating element 2 outer sealants 3 that are provided with; Leading body 4 is stranded on the sealant 3, on leading body 4, coats inner sheath 5, twines on the inner sheath 5 and teaches body 6; Teach body 6 to form by several conductors 7 and the insulating barrier 8 that is coated on the conductor 7; Teach the body 6 outer protective layers 9 that extrude.
The utility model provides a kind of version and implementation method of floating marine cable conductor; The above only is the preferred implementation method of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement, these improve the protection range that also should be regarded as the utility model.
