Abstract

The invention discloses a shielding longitudinal watertight degaussing cable and a production method thereof for ships. A tinned copper wire is impregnated with a sealant and then twisted into a twisted copper conductor which is impregnated with a conductor sealant layer on the periphery, an electro-insulating rubber layer is extruded on the periphery of the conductor sealant layer to form insulation core wires, chloroprene rubber filling bars are filled into gaps between the insulation core wires, and a plurality of insulation core wires are twisted wholly into a cable core. A cable core inner sealant layer, an inner jacket rubber layer, an armor shielding layer and an outer jacket rubber layer are sequentially arranged on the periphery of the cable core. A single wire of the cable conductor is impregnated with the sealant, the twisted copper conductor is impregnated with the conductor sealant layer on the periphery, the cable core inner sealant layer is extruded on the periphery of the cable core to form multiple sealing, the chloroprene rubber filling bars swell during follow-up vulcanization and can fill in the gaps inside the cable core completely, and tangency between the insulation core wires can be avoided, so that the sealant can permeate to the inside of the cable core to guarantee the watertight effect when the cable core inner sealant layer is extruded.

Description

technical field [0001] The invention relates to a cable, in particular to a shielded longitudinal watertight degaussing cable for ships; the invention also relates to a manufacturing method for a shielded 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 sealing and demagnetizat...
