Embodiment Construction

[0017] An umbilical cable embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] The present invention adopts the fiber cable that has been heat-drawn to be placed in the middle of the umbilical cable as the reinforcing cable 1; the straight fiber 2 is placed in parallel around the optical fiber 3 and the cable 4, effectively reducing the weight of the umbilical cable and reducing the stress on the umbilical cable. The force of the optical fiber 3 and the cable 4; the optical fiber 3 and the cable 4 are twisted into a convoluted structure as a whole, and the extension space formed by the convoluted structure can effectively improve the tensile performance; a layer of strengthening layer 6 is arranged outside the convoluted structure, The reinforcing layer 6 adopts strong fibers, which can effectively improve the axial rigidity; the gap between the convoluted structure and the reinforcing layer 6 is filled with...

Abstract

The invention relates to the technical field of cable manufacture, in particular to an umbilical cable. The umbilical cable is composed of a reinforcement cable, an optical fiber, an electric cable, a straight fiber, a functional fiber, a reinforcement layer and an insulation protection layer, wherein the reinforcement cable is a cable processed through hot stretching. The umbilical cable is stable in product structure, high in stretching resistance, high in bending resistance and deformation resistance, and high in extrusion resistance, and effectively protects the optical fiber and the electric cable by adding the reinforcement cable. Furthermore, ultimate bearing capacity of the umbilical cable is greatly improved, the application range of the umbilical cable is broadened, defects in the prior art and commercially available products are effectively remedied, and market requirements are met.

Description

technical field [0001] The invention relates to the technical field of cable manufacture, in particular to an umbilical cord. Background technique [0002] The umbilical cable (Umbilical) is a combination of electric cables (power cables or signal cables), optical cables (single-mode or multi-mode optical cables), hydraulic or chemical agent pipes (steel pipes or hoses). The main functions of the umbilical cable are: to provide electrical energy for the underwater production system; to provide hydraulic channels for the control of the underwater production system; to provide the chemical agent pipelines required for oil and gas field development; to transmit the control signals of the upper module and the sensor data of the underwater production system. [0003] At present, my country has become a big country in the production and application of umbilical cables. In recent years, with the development of society and economy, the requirements for umbilical cables are getting ...
