Abstract

The invention relates to a coaxial cable for use in a shallow sea bed and a manufacturing method thereof. The coaxial cable is characterized in that a high pressure polyethylene insulating layer is extruded outside the inner conductor; an outer conductor is uniformly woven at the periphery of the high pressure polyethylene insulating layer; two layers of polyester film strips are lapped at the periphery of the outer conductor in opposite directions. and the periphery of the polyester film strip is successively coated with a first asphalt coating layer, a first dipped hemp rope lining layer, a second asphalt coating layer, a copper alloy wire armor layer, a third asphalt coating layer, a second dipped hemp rope lining layer, a fourth asphalt coating layer, a aluminum plated magnesium alloy steel wire armor layer, a fifth asphalt coating layer, a first dipped hemp wrapped strip layer, a sixth asphalt coating layer, a second dipped hemp wrapped strip layer, a seventh asphalt coating layer and a plastic film anti-sticking layer. The cable is stable in structure, good in anti-water-seepage, corrosion-resistant and anti-pulling performances, and stable in signal transmission when water impact occurs.

Description

technical field

[0001] The invention relates to a communication cable, in particular to a coaxial cable for shallow sea bottom. The invention also relates to a method for manufacturing a coaxial cable for a shallow seabed. 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 of sea water due to their light weight, or they...
