Embodiment 1

[0024] Please refer to figure 1 A combined cable shown includes a positive power cord 1, a negative power cord 2, an armored optical fiber 3, a Kevlar sheath 4, a water-blocking yarn 5, a polyurethane foam layer 6 and a polyurethane protective layer 7;

[0025] The polyurethane material with high strength and special hardness is integrated with the strands after being cabled, endowing the whole cable with high strength. The new laminated structure provides a sheath system combining flexibility and strength, so that the cable can be rolled by underwater robots. The barrel can be retracted freely to enhance the longitudinal and transverse tensile and lateral pressure resistance, and ensure the low attenuation performance of the cable under dynamic conditions;

[0026] The diameters of the positive power line 1, the negative power line 2, and the armored optical fiber 3 are the same, and a triangular structure is formed between the positive power line 1, the negative power line 2...

Embodiment 2

[0031] Please refer to figure 2 A combined cable shown includes a positive power cord 1, a negative power cord 2, an armored optical fiber 3, a Kevlar braided sheath 4, a water-blocking yarn 5, a polyurethane foam layer 6 and a polyurethane protective layer 7, and the embodiment 1 The difference is that the positive power line 1 and the negative power line 2 both include oxygen-free bare copper wires, and the diameter interface of the oxygen-free bare copper wires is 14mm 2 , Using a single-strand wire, reducing consumables and reducing processing difficulty.

Abstract

The invention discloses a combined cable and belongs to the technical field of cables, and the combined cable comprises a positive power line, a negative power line, an armored fiber, a Kevlar braidedsleeve, waterproof yarns, a polyurethane foaming layer and a polyurethane protective layer, the diameters of the positive power line, the negative power line and the armored fiber are the same, and atriangular structure is formed among the positive power line, the negative power line and the armored fiber; gaps between the inner side of the Kevlar braided sleeve and the positive power line, thenegative power line and the armored optical fiber are filled with water-blocking yarns. According to the invention, the polyurethane material with high strength and special hardness is integrated withthe plied yarn into a whole after cabling; the whole cable is endowed with high strength, and a novel laminated structure provides a sheath system combining flexibility and strength, so that the cable can be wound and unwound freely in a winding drum of the underwater robot, longitudinal and transverse tensile strength and lateral pressure resistance are enhanced, and the low attenuation performance of the cable in a dynamic state is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a composite cable. Background technique [0002] At present, with the rapid development of the field of modern automation equipment, underwater drones, unmanned machinery, and other industries have unmanned equipment for all walks of life to increase production capacity, so the requirements for the supporting transmission cables With continuous improvement, the use environment, working mode and voltage level are also improved. When the cable is used frequently, it must move back and forth with the equipment at a high speed, and be collected by a reel to become the main supply cable for the robot. [0003] Cables have higher requirements on the electrical and mechanical properties of the insulation during frequent movement. Currently, the electrical performance life of this type of cable insulation in the market is very short. Contents of the invention [0004] The p...
