Problems solved by technology

[0002] Due to the narrow environment of cable laying in marine engineering, the use environment and place have the characteristics of humidity, saltiness, and high electromagnetic interference. Therefore, the requirements for the cables used are relatively high. Cables are generally set separately for signal cables, power cables, and instrument cables, and are wired independently, which takes up a lot of space, weak cable protection, and poor reliability

Abstract

The invention discloses a low-smoke halogen-free flame-retardant multifunctional armored cable for ship and marine engineering in the technical field of cables, comprising an electric power cable, an instrument cable and a coaxial signal cable which are distributed like three stacked cube blocks, a double-layer shielding layer lapped by an aluminum foil polyester composite strip is respectively arranged outside the electric power cable, the instrument cable and the coaxial signal cable, wherein polyester strip lapping layers are arranged outside the double-layer shielding layers of the electric power cable and the instrument cable, a filling material with sector-shaped cross section is respectively arranged in clearances among the peripheries of all cables, the electric power cable, the instrument cable, the coaxial signal cable and the filling material are twisted into a cable bundle, an external drainage wire is arranged outside the cable bundle, a total shielding layer is wholly lapped at the periphery of the cable bundle, an internal sheath is arranged outside the total shielding layer, a weaved armored layer is arranged outside the internal sheath, and an external sheath is arranged outside the weaved armored layer. The cable has a plurality of functions of transmitting an electric power signal, an instrument signal and a video signal, small laying space and compact structure, and can be used in ship or marine engineering.

Description

technical field [0001] The invention relates to a cable, in particular to a multifunctional cable for ships and ocean engineering. Background technique [0002] Due to the narrow environment of cable laying in marine engineering, the use environment and place have the characteristics of humidity, saltiness, and high electromagnetic interference. Therefore, the requirements for the cables used are relatively high. Cables are generally set separately for signal cables, power cables, and instrument cables, and are wired independently, which takes up a large space, weak cable protection, and poor reliability. When cables with different functions are combined in a whole cable, the mutual magnetic field and electric field interfere with each other, resulting in large loss on the signal line and easy signal loss. At present, there is no cable with different signals, especially power cables and cables. The practice of combining signal cables in one cable; how to make power transmis...
