Description
Technical Field
The utility model discloses a compound pipe cable of hydraulic control specifically is signal cable technical field.
Background
A signal cable is a signal transmission means. The signal cable has a very small transmitted signal, so as to avoid the signal interference, the signal cable is provided with a shielding layer outside, the shielding layer of the wrapped conductor is generally conductive cloth, a woven copper mesh or copper foil (aluminum), the shielding layer needs to be grounded, an external interference signal can be guided into the ground by the shielding layer, the interference of the interference signal entering the inner conductor is avoided, and the loss of the transmitted signal is reduced. The existing signal cable has weak transmission signal and complex manufacturing process, so in recent years, a lot of experts in China make a lot of researches on how to realize connection and transmission of a large number of zero magnetic field interference signals in a limited space. Therefore, a hydraulic control composite pipe cable is put into use to solve the problems.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
The hydraulic control composite pipe cable comprises an outer pipe 3 provided with a sheath 4, wherein an inner pipe 2 and a power cable 1 are embedded. The power cables 1 are laid helically and their length may optionally be greater than the length of the outer tube 3. The outer tube 3 is subjected to water pressure and is made of metal, preferably steel. It is welded longitudinally by laser or by arc welding under inert gas, or by plasma arc or any other suitable method. The outer tube 3 may also be made of an extruded plastic for imparting sufficient pressure resistance to the cable.
The inner pipe 2 of the hydraulically controlled composite umbilical is surrounded by a jacket 4, protecting it from corrosion or local crushing. The inner tube is arranged adjacent to the power cable 1, the power cable 1 being made of copper or aluminium or other metal or alloy and being a very good electrical conductor, the power cable 1 being wound in one or more spirals.
Around the power cable 1 is arranged a helical wire 6 having high mechanical strength and preferably made of steel, which helical wire 6 may constitute a single layer, or it may constitute a multilayer comprising a plurality of layers laid in the same direction or in opposite directions. The helical wire 6 provides mechanical traction strength to the cable, which also has an arched character, which is advantageous in particular if the outer tube 3 is made of plastic and does not have sufficient compressive strength.
In a preferred embodiment, the gaps between the helical wires 6 and the inner tube 2 may be filled with a sealing material, such as polyurethane resin or any other material capable of performing this sealing function, to resist the propagation of water in the longitudinal direction of the cable, in particular in case of damage to the submerged cable.
The thickness of the outer tube 3, made of polyethylene or any other electrically insulating and wear resistant material, formed as one or more layers on the helical wire 6, is set according to the degree of electrical isolation and mechanical protection required.
The inner tube 2 essentially performs a filling function to fill the resulting cable to a sufficiently large diameter to have satisfactory mechanical properties for use at great depths.
The armor is arranged on the inner wall of the outer pipe 3, is a metal armor and is formed by wrapping a metal belt or spirally winding a metal wire; the metal belt is wrapped and armored by steel belt double-layer gaps with the thickness of 0.2-0.8 mm; the metal wire is sheathed by a steel wire or an aluminum wire with the diameter of 0.8-4mm in a single-layer spiral winding way; the metal band or the metal wire is adopted to complete the armoring step, the metal band or the metal wire can be used for protecting the cable, so that the cable core is prevented from being damaged after the sheath of the cable is smashed, pressed and extruded, the tensile strength and the compressive strength are enhanced, the service life of the cable is prolonged, the anti-interference performance of the cable can be protected through the shielding effect, and the metal band or the metal wire has a better magnetic shielding effect
The metal armor is formed by spirally wrapping a single layer of low-carbon galvanized thin steel wires with the nominal diameter of 3.15mm in a left direction, and the winding pitch is 10 times of the diameter of the cable.
It is also advantageous that the sealing material is also filled with conductive particles, especially when the inner tube 2 is glued or not very smooth, to avoid any electrical problems at the interface between the conductive strips and the spiral wire.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
