Abstract

The invention discloses a strengthening tensile type longitudinal watertight degaussing cable for ships and warships and a manufacturing method of the strengthening tensile type longitudinal watertight degaussing cable, and belongs to the field of cables. A plurality of tinning copper wires are steeped with a sealant and is stranded to be a stranded copper conductor; a conductor sealant layer is steeped on the periphery of the stranded copper conductor; an insulated rubber layer is extruded at the periphery of the conductor sealant layer to form insulated core wires; a chloroprene rubber filling strip is filled in a gap among each insulated core wire and the plurality of insulated core wires are integrally stranded to form a cable core; a cable core sealant layer is extruded at the periphery of the cable core; and a sheath rubber layer is extruded at the periphery of the cable core sealant layer. A monofilament of the cable conductor is steeped with the sealant, the conductor sealant layer is steeped at the periphery of the stranded copper conductor, and a cable core sealant layer is extruded at the periphery of the cable core so as to form multiple sealing; and moreover, the chloroprene rubber filling strip is expanded during subsequent vulcanization and can be totally filled in the gap of the cable core, so that the insulated core wires are not tangential to each other, and the sealant can be infiltrated into the cable core to ensure the watertight effect.

Description

technical field [0001] The invention relates to a cable, in particular to a reinforced tensile longitudinal watertight degaussing cable for ships; the invention also relates to a manufacturing method of a reinforced tensile longitudinal watertight degaussing cable 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 seali...
