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 the utility model belongs.Herein in the utility model
Term used in the description, which is only for the purpose of describing specific embodiments, to be not intended to limit the utility model.
Fig. 1 shows the structural schematic diagram of the umbilical cables 100 of an embodiment of the present invention.The umbilical cables 100 can be with
(for example, underwater 11000m) is required for underwater production operation deeper than the existing umbilical cables using wire armouring,
It can be used as the umbilical cables of ROV (Remote Operated Vehicle, underwater robot) connection lash ship.
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 outer surface of wrapping layer 20 is arranged in the sheath 30 by way of extruding.
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
