Abstract

The invention discloses a longitudinal watertight cable for vessel in the technical field of watertight cables. A first waterproof sealant is arranged outside a plurality of cables, a gap between thefirst waterproof sealant and a cable is filled with a water blocking filler, an inner sheath is arranged outside the first waterproof sealant, a shielding layer is arranged outside the inner sheath, asecond waterproof sealant is arranged outside the shielding layer, and an outer sheath is arranged outside the second waterproof sealant. The longitudinal watertight cable is good in sealing performance, and can bear capability of high-pressure water moving along a longitudinal direction of the cable, and the cable has the advantages of high flame retardance, no halogen, low toxicity, moderate mobility of the filler and high pressure resistance and is applicable to the development requirement of the vessel and deep-water equipment.

Description

technical field [0001] The invention belongs to the technical field of watertight cables, in particular to a longitudinal watertight cable for ships. Background technique [0002] Watertight cables are generally divided into two types: horizontal watertight cables and longitudinal watertight cables. In case of damage to the sheath of the longitudinal watertight cable, the cable sheath and the internal sealing packing of the cable are used to slow down the flow rate of water entering the cable and improve the reliability of the equipment. [0003] Longitudinal watertight cables are generally composed of outer sheath, shielding layer, wrapping tape, conductor and water-blocking material. The outer sheath is usually chloroprene rubber, the insulating material is ethylene propylene rubber, the conductor is generally copper wire or tinned copper wire, the insulated wire core is twisted and vulcanized, and the shielding layer is prepared outside, and finally the outer sheath is v...
