Watertight umbilical and photoelectric hybrid cable

Abstract

A watertight umbilical and photoelectric hybrid cable disclosed by the present invention comprises a cable core and an enhancing layer lapping the cable core, and the cable core comprises an optical fiber, a stainless steel loose tube, the low-voltage watertight electric wires, the high-voltage watertight electric wires and an inner protection layer. The optical fiber is installed in the stainlesssteel loose tube, the multiple strands of low-voltage watertight electric wires are twisted on the stainless steel loose tube, and the inner protection layer wraps the low-voltage watertight electricwires; the high-voltage watertight electric wires are twisted on the inner protection layer, the enhancing layer wraps the watertight electric wires, the curing type water-blocking sealants are filled between the enhancing layer and the high-voltage watertight electric wires and between the stainless steel loose tube and the low-voltage watertight electric wires respectively, and an outer protection layer is arranged on the enhancing layer. The watertight umbilical and photoelectric hybrid cable of the present invention effectively solves the problems that the signal transmission distance andthe communication capacity are limited, the function is single, during the large tension repeated contraction and release, the signal transmission is not stable, and the service life is reduced, andguarantees the overall mechanical performance and the transverse water-pressure resistant capability.

Description

technical field [0001] The invention relates to a cable for underwater marine work, in particular to a watertight umbilical cord photoelectric hybrid cable. Background technique [0002] The watertight umbilical cable is mainly used to connect the underwater marine operation equipment and the surface operation vessel, and the retractable operation is carried out through the winch. Underwater marine operation equipment collects relevant state data, image data, etc. required for operation, and transmits them to the measurement and control platform for data processing through the photoelectric transmission line of the watertight umbilical cable, and the measurement and control platform transmits control signals to the underwater marine operation equipment through the photoelectric transmission line of the watertight umbilical cable . In addition, the underwater marine equipment measurement and control platform provides power feed for underwater marine equipment through the pow...
