Problems solved by technology

Although this type of cable can meet the requirements of marine engineering cables in the short term, it still has disadvantages: the cable uses steel wire as a load-bearing member, and the steel wire has a large specific weight. It is not conducive to laying and use, and it is also not conducive to use in deeper seabeds; this type of cable is armored with steel wire. Since the steel wire is a magnetic metal, hysteresis loss occurs during the transmission of the power cable, causing interference to the core. In order to avoid For this type of interference, a shielding layer needs to be added inside the armor layer, which increases materials and costs; metal pipes and wire armor are used as sampling pipelines and load-bearing structures are easily shaken by deep water pressure and buoyancy, resulting in cable insulation Damage to the material, short-circuiting the cable due to insulation operations
Notification number is the utility model patent of CN203366804U, although it adopts the braided fabric layer that polyethylene fiber and non-woven fabric wrapping constitutes as non-metal reinforcement layer to improve load weight, it still has shortcoming, the first, the braided fabric is used as a whole The reinforcement layer is not used as an armor wire, which makes it inconvenient to use, and it is not convenient to adjust the layout of the armor layer according to the depth of the umbilical cable to achieve the required strength; second, the overall tensile strength of the reinforcement layer Strength and tensile modulus are not conducive to control; third, the adaptability to the environment such as temperature, chemical resistance, etc. is not strong; fourth, it is not easy to produce and assemble
The existing technology also uses FRP and aramid fiber as the braid layer, but its tensile strength and tensile modulus are relatively insufficient, and it is impossible to produce ultra-long armored wires, which is not conducive to use in deep sea below 10,000 meters
[0005] The prior art does not disclose a production method suitable for high-performance non-metallic armored wire, especially a production method that can realize continuous extrusion molding, a high degree of automation control, high production efficiency, and continuous large lengths, which seriously restricts high-quality Development of performance non-metallic armor wire

At the same time, the method can realize the continuous production of non-metallic armored wire with large length.

Description

technical field [0001] The invention relates to a production method of an armored wire for an umbilical cord, belonging to the technical field of composite optical cable materials. Background technique [0002] As the key equipment for deep-sea energy development, the umbilical cable is responsible for the communication of "signal" and "material" between the sub-system of underwater exploitation and the surface floating mother platform. It occupies a very important position in the process of underwater oil and gas development. The "nervous system" and "umbilical cord of life". [0003] With the continuous breakthrough of the maximum diving depth of Remotely Operated Vehicles (ROV), especially the 10,000-meter deep-sea ROV development project, the development of umbilical cables for deep-sea ROVs has become an urgent task for my country's deep-sea technology. However, the existing deep-sea ROV umbilical cables are metal-armored umbilical cables, and steel wires are used as t...
