Shallow seabed symmetric audio communication cable and manufacture method thereof

Abstract

The invention relates to a shallow seabed symmetric audio communication cable and a manufacture method thereof. A high pressure polyethylene insulation layer is extruded outside a copper conductor to form an insulated wire core, four insulation cores with different colors are twisted into star quads, the four star quads are respectively wound outside a polyethylene pad core, a measurement copper wire is arranged in the polyethylene pad core, signal wires are respectively arranged between the peripheries of every two adjacent star quads and are twisted into a core, and a polyester film strip, a high pressure polyethylene sheath, a first impregnated hemp rope, a first asphalt coating layer, a copper alloy wire anchoring layer, a second asphalt coating layer, a second impregnated hemp rope lining layer, a third asphalt coating layer, an aluminum magnesium alloy plated steel wire anchoring layer, a fourth asphalt coating layer, a first impregnated gird layer, a fifth asphalt coating layer, a second impregnated gird layer, a sixth asphalt coating layer and a plastic film adhering-preventing layer are sequentially coated on the periphery of the core. The shallow seabed symmetric audio communication cable is capable of transmitting communication and control signals, and has the advantages of stable structure, seepage prevention, corrosion resistance, good pulling resisting property, and stable signal transmission during water impaction.

Description

technical field [0001] The invention relates to a communication cable, in particular to a shallow sea submarine symmetrical audio communication cable. The invention also relates to a manufacturing method of a shallow sea submarine symmetrical audio communication cable. Background technique [0002] With the development and utilization of marine energy, more and more submarine cables are used as current-carrying equipment for submarine signal transmission, and the technical requirements are also getting higher and higher. In particular, cables are required to have excellent mechanical, physical and electrical properties, and to ensure that they can withstand the impact of seawater immersion. Excellent signal transmission performance, anti-seepage, seawater corrosion resistance, tensile mechanical properties, long service life and high reliability. Ordinary communication cables used on the seabed will either cause cable damage and serious signal attenuation due to the impact ...

AI Technical Summary

Problems solved by technology

Ordinary communication cables used on the seabed will either cause cable damage and serious signal attenuation due to the impact of sea water due to their light weight, or they will be easily damaged due to their heavy weight due to their high tensile force; Arrange the communication cable and the power cable together to form a composite cable. Although this structure ensures the structural safety of the communication cable, it is easy to cause the strong electric field of the power cable to affect the signal transmission of the communication cable, and for some cables that do not need power In the case where only communication cables are needed, if composite cables are used, resources will be wasted seriously, and if composite cables are not used, it will easily lead to poor adaptability of communication cables to the environment
