A high-voltage composite umbilical cable and its manufacturing process

Abstract

The invention discloses a high-voltage composite umbilical cord, which comprises an inner layer functional unit group, an outer layer functional unit group and an outer sheath, and the inner layer functional unit group includes three inner layer medium voltage cable units arranged at the center And the inner layer is filled with steel pipe units, the outer layer functional unit group includes four outer layer steel pipe units, the four outer layer steel pipe units divide the outer periphery of the outer layer functional unit into four installation areas, and three installation areas are respectively equipped with The outer medium voltage cable unit, two low voltage cable units, the outer filled steel pipe unit and the filling body, and the steel strand unit, the two low voltage cable units, the outer filling steel pipe unit and the filling body in another installation area. The invention provides a high-voltage composite umbilical cord and its manufacturing process. The umbilical cord has high tensile strength, light weight and is 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] Umbilical cable is a combination of cable, optical cable and hydraulic pipe. Its main functions are: 1. Provide power for underwater production system; 2. Provide hydraulic channel for underwater production system control; 3. Provide chemical pipelines required for oil and gas field development; 4. .Transmit the control signal of the upper module and the sensor data of the underwater production system. [0003] Conventional umbilicals are usually reinforced with steel wire armor. However, the weight of the umbilicals will increase, and a large number of buoyancy blocks need to be added to the umbilicals, which greatly increases equipment costs and offshore construction costs. It will also lead to complicated umbilical production process and affect production efficiency. S...
