Abstract

The invention discloses a bundled integrated dynamic cable for an offshore oil system, which comprises a power transmission insulating core unit, an optical fiber communication unit, a pipeline unit, a control cable unit, a filling reinforcement unit, an inner sheath, an armored reinforcement unit and an outer sheath ; Three identical power transmission insulated wire core units are stranded, and the pipe unit, the optical fiber communication unit and the control cable unit are respectively embedded in the three large gaps, and the solid core is filled with filling reinforcement units in the entire cabled stranded unit, The cabled unit is covered with an inner sheath, the inner sheath is wound with an armored reinforcement unit, and the armored reinforcement unit is extruded with an outer sheath. The cable structure of the present invention is reasonably designed, capable of simultaneously transmitting multi-circuit power consumption, changing the design scheme of single-circuit power supply of conventional submarine cables, reducing the laying space, and avoiding various hidden dangers caused by complicated laying of many submarine cables in a narrow space.

Description

technical field [0001] The invention relates to a cable, in particular to a bundled integrated dynamic cable for an offshore oil system. Background technique [0002] my country is a country with a large population and is also a country with poor oil resources. At present, more than half of the oil needs to be imported from abroad; at this stage, my country's offshore oil exploration is still in the offshore and shallow sea stage; offshore oil and gas resources are also depleting day by day, urgently needed Developing towards deep-sea oil production, deep-sea oil production requires a more technically demanding and more stable underwater Christmas tree system, which plays an important role as a bundled integrated dynamic cable for the offshore oil system connecting the main control equipment and each oil production point for power, control, and communication equipment. role. It mainly involves the following aspects: [0003] 1) Power motors, hydraulic systems, valves, etc. n...
