Description recognizes it is the prior art not because not being included in this part.
Umbilical cables are for a kind of cable used in subsea production operation.Existing umbilical cables use wire armouring, because
By wire armouring umbilical cables intensity/underwater dead load than being limited, existing umbilical cables are usually less (maximum using the depth of water
It is typically not greater than 6000 meters using the depth of water), it cannot be satisfied deeper underwater production operation requirement.
Invention content
In view of this, it is necessary to provide a kind of umbilical cables, has the characteristics that low-gravity, intensity are high, can be used in than existing
The deeper underwater production operation requirement of wire armouring umbilical cables.
A kind of umbilical cables provided by the invention, including cable core, the sheath that is set to outside cable core and be fixed in described
Armor outside sheath, the armor include several armouring silks, and every armouring silk includes by fibre reinforced composites
Manufactured matrix.
Further, the armor on several armouring silks by coating adhesive and being twisted.
Further, including at least two layers armor, adjacent armor direction of lay are opposite.
Further, the diameter positioned at the armouring silk of the armor of internal layer is more than the armouring silk of the armor positioned at outer layer
Diameter.
Further, described matrix is made of aramid fiber enhancing composite material.
Further, described matrix includes aramid fiber yarn, high molecular polymer matrix, initiator and releasing agent.
Further, every armouring silk further includes the wear-resisting and/or seawater corrosion resistance being arranged in described matrix outer surface
Protective layer.
Further, the protective layer is made of nylon.
Further, the umbilical cables further include the wrapping layer being set to outside the cable core.

Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.It is appreciated that attached drawing is only for reference and description, not it is used for this hair
It is bright to limit.The connection shown in attached drawing does not limit connection type only for ease of clearly describing.
It should be noted that when a component is considered as " connection " another component, it can be directly to separately
One component may be simultaneously present component placed in the middle.Unless otherwise defined, all technologies used herein and section are academic
Language has the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.Herein in the description of the invention
Used term, which is only for the purpose of describing specific embodiments, is not intended to limit the present invention.
Fig. 1 shows the structural schematic diagram of the umbilical cables 100 of one embodiment of the invention.The umbilical cables 100 can be used for
Underwater production operation deeper than the existing umbilical cables using wire armouring requires (for example, underwater 11000m), can make
For the umbilical cables of ROV (Remote Operated Vehicle, underwater robot) connection lash ships.
The umbilical cables 100 include cable core 10, wrapping layer 20, sheath 30 and armor 40, and the wrapping layer 20 is wrapped
The cable core 10 is covered, the sheath 30 is arranged by way of extruding in the outer surface of wrapping layer 20.
In the present embodiment, the cable core 10 may include at least one power cable unit 11, at least one control cable
Unit 12, at least a stainless steel fiber unit 13 and at least one ground cable unit 14.Power cable unit 11, control electricity
Cable unit 12, stainless steel fiber unit 13 and ground cable unit 14 constitute cable core 10 by the way that spiral is twisted.Wherein, power electric
Cable unit 11, control cable unit 12, the respective quantity of stainless steel fiber unit 13 and ground cable unit 14 can be according to
It is arranged according to actual conditions, in present embodiment, the cable core 10 may include three power cable units 11, two control electricity
12, stainless steel light units 13 of cable unit and six ground cable units 14.Each power cable unit 11, control electricity
