Problems solved by technology

[0003] Conventional umbilical cables are usually reinforced with steel wire armor, but the weight of the umbilical cable will increase, and a large number of buoyancy blocks need to be added to the umbilical cable, which greatly increases equipment costs and offshore construction costs. In addition It will also lead to complicated manufacturing process of umbilical cable, affecting production efficiency

Abstract

The invention discloses a high-voltage composite umbilical cable. The high-voltage composite umbilical cable comprises an inner-layer functional unit group, an outer-layer functional unit group and an outer sheath, wherein the inner-layer function unit group comprises three inner-layer medium-voltage cable units arranged in the center and an inner-layer filling steel pipe unit, and the outer-layer function unit group comprises four outer-layer steel pipe units. The four outer-layer steel pipe units divide the periphery of the outer-layer function unit into four installation areas, wherein an outer-layer medium-voltage cable unit, two low-voltage cable units, an outer-layer filling steel pipe unit and a filling body are arranged in three of the installation areas respectively. A steel strand unit, two low-voltage cable units, an outer layer filling steel pipe unit and a filling body are arranged in the other mounting area. According to the high-voltage composite umbilical cable and the manufacturing process thereof, the umbilical cable is high in tensile strength, light in weight and convenient to manufacture.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-voltage composite umbilical cable and a manufacturing process thereof. Background technique [0002] The umbilical cable is a combination of cables, optical cables, and hydraulic pipes. Its main functions are: 1. Provide electricity for the underwater production system; 2. Provide hydraulic channels for the control of the underwater production system; 3. Provide chemical agent pipelines for oil and gas field development; 4. .Transfer the control signal of the upper module and the sensor data of the underwater production system. [0003] Conventional umbilical cables are usually reinforced with steel wire armor, but the weight of the umbilical cable will increase, and a large number of buoyancy blocks need to be added to the umbilical cable, which greatly increases equipment costs and offshore construction costs. In addition It will also lead to complicated manufacturing pr...
