Abstract
The invention relates to the technical field of cable manufacture, in particular to an umbilical cable. The umbilical cable is composed of a reinforcement cable, an optical fiber, an electric cable, a straight fiber, a functional fiber, a reinforcement layer and an insulation protection layer, wherein the reinforcement cable is a cable processed through hot stretching. The umbilical cable is stable in product structure, high in stretching resistance, high in bending resistance and deformation resistance, and high in extrusion resistance, and effectively protects the optical fiber and the electric cable by adding the reinforcement cable. Furthermore, ultimate bearing capacity of the umbilical cable is greatly improved, the application range of the umbilical cable is broadened, defects in the prior art and commercially available products are effectively remedied, and market requirements are met.
Description
Technical field
The present invention relates to cable manufacturing technology field, be specifically related to a kind of umbilical cables.
Background technology
Umbilical cables (Umbilical) is the combination of cable (power cable or signal cable), optical cable (single mode or multimode optical cable), hydraulic pressure or chemical agent pipe (steel pipe or flexible pipe).The major function of umbilical cables has: for subsea production system provides electric energy; For subsea production system control provides hydraulic channel; Provide oil-gas field development required chemical agent pipeline; Transmit control signal and the subsea production system sensing data of upper module.
At present, China has become the big country that umbilical cables is produced and applied.In recent years, along with socioeconomic development, more and more higher to the requirement of umbilical cables, traditional poor, yielding, anti-extrusion performance of umbilical cables structural instability, stretch-proof performance was poor and proportion is also larger, also had the problems such as easy damaged is not easy to operate.
So study, a kind of Stability Analysis of Structures, stretch-proof performance are high, the high umbilical cables of high, the anti-extrusion performance of bending resistance anti-deformation is the significant problem of current cable facing manufacturing technology.
Summary of the invention
The technical problem to be solved in the present invention is how to overcome the deficiency that prior art exists, and a kind of umbilical cables is provided.Product structure of the present invention is stable, stretch-proof performance is high, high, the anti-extrusion performance of bending resistance anti-deformation is high.
Technical solution of the present invention is: a kind of umbilical cables, described umbilical cables is provided with reinforcement cable, described reinforcement cable is the cable of hot drawing-off processing, the parallel umbilical cables center that is placed in of described reinforcement cable, described reinforcement cable outer setting has optical fiber and cable, described optical fiber, between cable and reinforcement cable, be provided with straight fiber, described straight fiber is parallel is placed in optical fiber and cable around, described optical fiber, whole cable is twisted into curls up structure, the described structure outside of curling up is provided with reinforced layer, described reinforced layer and the gap-fill curling up between structure have functional fiber, described reinforced layer outer setting has insulating protective layer.
Described hot drawing-off processing comprises preliminary treatment, preliminary draft, prebake, drawing-off for the second time and drying course, effectively improves and strengthens cable intensity, reduces elongation.
Described straight fiber effectively reduces umbilical cables weight, optical fiber, cable is formed to effective protection simultaneously.
Described reinforced layer adopts strong fiber, effectively improves axial stiffness.
The described structure of curling up, forms wider space, effectively carries high tensile performance.
Described functional fiber, in the time that umbilical cables is squeezed or is bending, effectively improves its resistance type ability, ensures that umbilical cables structure is more stable simultaneously.
Described insulating protective layer has the function of insulation, wear-resisting, waterproof.
The invention has the advantages that Stability Analysis of Structures, higher, the anti-extrusion performance of higher, the counter-bending anti-deformation of stretch-proof performance are higher.The present invention be advantageous in that by increase and strengthen cable, effectively protected optical fiber and cable, greatly improved the ultimate bearing capacity of umbilical cables, widened the range of application of umbilical cables, effectively make up the defect of prior art and commercially available prod, meet the need of market.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is embodiment of the present invention structural representation
Fig. 2 is that the embodiment of the present invention is curled up structural representation
Embodiment
Below ginseng is made accompanying drawing, describes a kind of umbilical cables embodiment of the present invention in detail.
The present invention adopts in the middle of the fiber rope of overheated drawing-off processing is positioned over umbilical cables to make to strengthen cable 1; Straight fiber 2 is parallel is placed in optical fiber 3 and cable 4 around, effectively reduces the weight of umbilical cables, alleviates stressed to optical fiber 3, cable 4 simultaneously; Described optical fiber 3, cable 4 entirety are twisted into and curl up structure, described in curl up structure form wider space can effectively carry high tensile performance; The described structure outside of curling up is provided with one deck reinforced layer 6, and described reinforced layer 6 adopts strong fiber, can effectively improve axial stiffness; Have functional fiber 5 curling up gap-fill between structure and reinforced layer 6, effectively ensure that umbilical cables is squeezed or resistance type ability when bending, umbilical cables structure is more stable simultaneously; It is coated that last entirety is carried out insulating protective layer 7.
