Abstract

The invention discloses a longitudinal watertight degaussing cable for a warship and a manufacturing method thereof, belonging to the field of cables. After being soaked in sealing glue, a plurality of tin-coated copper wires are stranded into a stranded copper conductor; a conductor sealing glue layer is coated on the stranded copper conductor; an insulating rubber layer is wrapped on the periphery of the conductor sealing glue layer in an extruding way to form an insulating core wire; chloroprene rubber filling strips are filled in clearances between insulating core wires; a plurality of insulating core wires are integrally stranded into a cable core; a cable core sealing glue layer is coated on the periphery of the cable core in the extruding way; and a sheath rubber layer is coated on the periphery of the cable core in the extruding way. The sable conductor is soaked in the sealing glue, the conductor sealing glue layer is coated on the periphery of the stranded copper conductor, and the cable core sealing glue layer is coated on the periphery of the cable core in the extruding way to achieve a multiple sealing effect. The chloroprene rubber filling strips can swell and completely fill clearances in the cable cores during subsequent vulcanization, and the insulating core wires are not tangential any more, so that when the cable core sealing glue layer is coated in the extruding way, the sealing glue can penetrate into the cable core, and a watertight effect is ensured.

Description

technical field [0001] The invention relates to a cable, in particular to a longitudinal watertight degaussing cable for ships; the invention also relates to a manufacturing method for the longitudinal watertight degaussing cables for ships. Background technique [0002] Due to the importance of stealth during navigation, ships, especially underwater ships, especially need to prevent magnetic mine attacks. For this reason, the hull needs to be degaussed frequently. Fixed degaussing can be degaussed at the degaussing station, but for the induced magnetic field generated by the underwater ship that is in the process of sailing for a long time, it needs to be degaussed with the help of the degaussing system installed outside the ship itself. However, due to the particularity and complexity of the underwater ship's navigation environment, ordinary degaussing cables cannot simultaneously meet the technical requirements for both longitudinal sealing and demagnetization performance...
