[0024] In one embodiment, Figure 1-Figure 3 As shown, a layered braided control line comprises: a control line core structure and a functional protective sleeve structure coated on the outside of the control line core structure, wherein the control line core structure is composed of a conductor made of a plurality of tinned copper wires twisted together and an outer extruded insulating layer, wherein the insulating layer is made of EPDM rubber or fluoroplastic; the functional protective sleeve structure is sequentially provided with a shielding structure layer, a braiding structure layer and a coating layer from the inside to the outside; the shielding structure layer comprises a first shielding layer, a second shielding layer and a third shielding layer, and the braiding structure layer comprises a first braiding layer, a second braiding layer and a third braiding layer;

[0025] The materials of the first shielding layer, the second shielding layer and the third shielding layer are all made of graphene materials, the materials of the first braided layer, the second braided layer and the third braided layer are all made of a mixed weaving of high-strength fiber and tinned copper wire, and the material of the covering layer is made of chloroprene rubber material;

[0026] The high-strength fiber is one or more of basalt fiber, aramid fiber, and carbon fiber;

[0027] The resistance of the copper wire is ≦0.132Ω / km, and the insulation resistance of the insulation layer is ≧390MΩ.km.

[0028] A method for manufacturing a layered braided control line comprises the following steps:

[0029] Step 1: Control core structure processing: manufacturing conductor strands of power cores, taking multiple conductor strands and two control cores;

[0030] Step 2: Cable core manufacturing: wrap the conductor strands and control cores outside the air guide tube to form the cable core;

[0031] Step three, functional protective sleeve structure processing: the prepared shielding structure layer including the first shielding layer, the second shielding layer and the third shielding layer is coated on the outside of the cable core in sequence through a coating device, and then the prepared braided structure layer including the first braided layer, the second braided layer and the third braided layer is coated on the outside of the shielding structure layer in sequence through a coating device, and finally the covering layer is coated on the outside of the braided structure layer through a coating device to obtain a control line.

[0032] After the cable core is prepared, it is necessary to release the stress of the cable core online through a cable core stress release device; the cable core stress release device includes a frame and a wheel set connected to the frame;

[0033] The principle of the cable core stress release device is that after the cable core is manufactured, it goes down into the functional structure part of stress release. Here, because the cable core is wrapped with metal materials such as conductors, it has a heavy mass. If the stress is released in the horizontal direction, the metal conductor parts of the upper and lower parts of the cable core are subjected to different forces, and the stress release is uneven. In the functional structure part of stress release, the most important structure of stress release is two conical wheels. On the surface of the two conical wheels, the cable core is free to move axially along the conical surface along the conical wheel due to its own large stress, thereby increasing or decreasing the path length. At the same time, on the upper and lower follower guide wheels, the cable core is restricted by the follower wheel, and then the follower guide wheel is driven to perform axial and / or radial movements under the action of the cable core stress. At this time, due to the damping structure in two directions, this part of the stress work can be converted into potential energy, and part of the potential energy can be converted into internal energy. Due to the uncertainty of the position of the follower guide wheel, the return guide wheel is used below the lower follower guide wheel to return the deviated cable core to its position, and then the rear steering guide wheel group is turned to move horizontally.

[0034] After stress release, the roundness of the cable core will decrease. Therefore, the cable core is adjusted to be round by the full-circle pressing wheel group before entering the process of wrapping the isolation tape and extruding the sheath. In the full-circle pressing wheel group, the cable core is strongly compressed by adjusting the hydraulic strength of the compression link. At the same time, new stress will be generated in this process. In order to reduce stress and eliminate new stress, multiple sets of full-circle pressing wheel groups are used. At the same time, hydraulic method (not rigid connection method) is used. Once the pressure threshold is exceeded, the compression link will retract to release the excess stress on the cable core.

[0035] Step 1: Control core structure processing: To manufacture the conductor strands of the power core, take multiple conductor strands and two control cores. The conductor strands are composed of single filaments with a diameter not greater than 0.18 mm, and the bundled section diameter ratio is 20-25 times.

[0036] Step 1: Control core structure processing: To manufacture the conductor strands of the power core, multiple conductor strands and two control cores are taken. The control core is firstly formed by bundling single filaments to form a flex-resistant conductor, and then covered with fluoroplastic to obtain an insulating layer; the bundled section diameter ratio is 16-22 times.

[0037] Step 1: Control core structure processing: manufacture the conductor strands of the power core, take multiple conductor strands and two control cores, the two control cores are adjacent, and the air duct is filled with gas.

[0038] Step three, functional protective sleeve structure processing: the prepared shielding structure layer including the first shielding layer, the second shielding layer and the third shielding layer is coated on the outside of the cable core in sequence through a coating device, and then the prepared braided structure layer including the first braided layer, the second braided layer and the third braided layer is coated on the outside of the shielding structure layer in sequence through a coating device, and finally the coating layer is coated on the outside of the braided structure layer through a coating device, so that in the control line, the thickness of the first shielding layer, the second shielding layer and the third shielding layer are all 0.12mm-0.25mm.

[0039] Step three, functional protective sleeve structure processing: the prepared shielding structure layer including the first shielding layer, the second shielding layer and the third shielding layer is coated on the outside of the cable core in sequence through a coating device, and then the prepared braided structure layer including the first braided layer, the second braided layer and the third braided layer is coated on the outside of the shielding structure layer in sequence through a coating device, and finally the covering layer is coated on the outside of the braided structure layer through a coating device, so that in the control line, the braiding density of the first braided layer, the second braided layer and the third braided layer are all greater than 94.5%.

[0040] The present invention, which is a control line made of a control line core structure and a functional protective sleeve structure covering the outside of the control line core structure, adopts a multi-layer shielding structure and a layered braiding structure, which can effectively improve the anti-interference ability, is suitable for scenarios such as electronic equipment with high requirements for signal transmission, and can effectively avoid the control line core from breaking during frequent bending and movement, thereby facilitating the use of the control line core.
