Abstract
The utility model discloses a vessel shielding-type longitudinal watertight degaussing cable in the field of cables. After dipped with sealant, a plurality of tin-coated copper wires are twisted together, thereby forming twisted copper conductors. The outer peripheries of the twisted copper conductors are dipped with conductor sealant layers. The outer peripheries of the conductor sealant layers are wrapped with insulating rubber layers, thereby forming insulating core wires. Gaps among the insulating core wires are filled with neoprene rubber filling strips and the insulating core wires are twisted together integrally, thereby forming a cable core. A cable core inner sealant layer wraps the periphery of the cable core in an extruded manner. An inner sheath rubber layer wraps the periphery of the cable core inner sealant rubber layer in an extruded manner. According to the utility model, the single conductor wires of the vessel shielding-type longitudinal watertight degaussing cable are dipped with the sealant, the outer peripheries of the twisted copper conductors are dipped with the conductor sealant layers, and the periphery of the cable core is wrapped by the cable core inner sealant layer in an extruded manner, thereby forming multiple sealing protection. The neoprene rubber filling strips expand in a follow-up vulcanizing process and can fill the gaps in the cable core completely, thereby causing the insulating core wires to be separated from each other. Therefore, the sealant can penetrate into the cable core when the cable core inner sealant layer is extruded, thereby guaranteeing the watertight effect.
