Abstract

The invention discloses an umbilical cable comprising an optical unit assembly, liquid transmission assemblies and power line cores. The optical unit assembly includes an optical fiber, optical unit reinforcing steel wires and an optical unit sheath, wherein the optical unit reinforcing steel wires and the optical unit sheath sequentially coat the optical fiber. Each power line core includes conductors coated with insulating layers, and the insulating conductors are stranded and then coated with a sheath. The optical unit assembly, the liquid transmission assemblies and the power line cores are stranded and then sequentially coated with a cable core sheath, two armor layers and an outer sheath. The outer layer of the cable is coated with the two armor layers and the outer sheath, which improves the water resistance and corrosion resistance of the cable.

Description

technical field [0001] The invention relates to a cable mainly used in marine engineering, in particular to an umbilical cable. Background technique [0002] At present, the main functions of the umbilical cable are: 1. Provide power for the underwater working system, 2. Provide hydraulic channels for the underwater production control system, 3. Provide chemical agent pipelines for oil and gas field development, 4. Transmit control signals; When used in the ocean, in order to adapt to the ocean environment, the umbilical cable needs to be suitable for submarine projects such as submarine trenching, submarine salvage, submarine mining, submarine exploration, submarine robots, and large-scale submarine tourism projects. The umbilical cable used for marine engineering is generally a A high-tech comprehensive cable that integrates power transmission, digital signal transmission, video signal transmission, and gas and liquid transportation. The cable needs to have an electromagne...
