Reinforced tensile screening type vertical watertight degaussing cable for ship and manufacturing method thereof

Abstract

The invention discloses a reinforced tensile screening type vertical watertight degaussing cable for a ship and a manufacturing method thereof. A twisted copper conductor is formed by soaking a plurality of tinned copper wires in a sealant and then twisting the tinned copper wires; a conductor sealant layer is soaked on the periphery of the twisted copper conductor; insulating rubber layers are extruded on the periphery of the conductor sealant layer; an aramid fiber reinforcing layer is weaved on the periphery of each insulating rubber layer so as to form an insulating core wire; chloroprene rubber filling strips are filled into gaps among the insulating core wires, and a cable core is integrally formed by twisting the insulating core wires; a cable core inner sealant layer is extruded on the periphery of the cable core; and an inner jacket rubber layer is extruded on the periphery of the cable core inner sealant layer. A plurality of seals are arranged on the periphery of a cable conductor, and the chloroprene rubber filling strips expand in a follow-up vulcanization process, thus entirely filling the gaps in the cable core; and one insulating core wire is not tangential to another insulating core wire. Therefore, when the cable core inner sealant layer is extruded, the sealant can permeate inside the cable core, so that the watertight effect can be ensured.

Description

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