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.
