Abstract

The invention discloses a communication cable special for sea. The communication cable special for sea comprises a cable core composed of three communication cable core pairs. Each communication cable core pair comprises two communication conductors and first shielding layers located at the peripheries of the communication conductors. The two communication conductors of each communicable cable core pair are twisted in pairs, and different twisted pitches are adopted in the three communication cable core pairs. Gaps between the communication cable core pairs are filled with insulating materials with rounded cable cores. An inside liner, an inner protective layer, a second shielding layer, a water-blocking layer, a protective layer and an outer sheath are sequentially arranged at the periphery of the cable core, wherein the inside liner is formed by wrapping a plurality of levels of wrapping tape, and the positions between the different levels of wrapping tape are filled with talcum powder. The water-blocking layer comprises two layers of water-blocking tape, a plurality of floating elements are arranged between the two layers of water-blocking tape, and gaps between the floating elements are filled with water-blocking powder. The communication cable special for sea is simple in structure, highly resistant to corrosion, excellent in waterproof performance and low in using cost.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a special communication cable for sea. Background technique [0002] Under the background that the ocean has entered the stage of large-scale development, marine cables have entered a stage of rapid development. In the marine environment, ships often need to communicate with other ships and offshore platforms, and communication cables are mainly used in the communication transmission process. In the prior art, marine communication cables still have problems such as insufficient waterproof performance and corrosion resistance that cannot adapt to marine corrosive environments. At the same time, the existing marine communication cables are relatively expensive, which is not conducive to popularization. Contents of the invention [0003] In order to solve the technical problems in the background technology, the present invention proposes a special marine communication cable for co...
