Abstract
The invention discloses a pressure sensor cable for a naval ship, and belongs to the technical field of wires and cables for ships. The pressure sensor cable comprises a cable core, a polyester belt, a shielding layer and an outer sheath, wherein the cable core is formed by arranging a plurality of wire cores and solid strips on the periphery of a blank pipe at intervals, the polyester belt wraps the cable core, and the shielding layer and the outer sheath are sequentially arranged outside the polyester belt from interior to exterior. A set of filling cores are arranged between the polyester belt and the shielding layer. The filling cores are Kevlar fiber reinforcing parts. The outer sheath is a polyvinylidene fluoride sheath. The pressure sensor cable has the advantages that the high-strength Kevlar fiber reinforcing parts can not only improve the longitudinal and mechanical tension resistance of the cable, but also remarkably improve the whole tensile strength of the cable; due to the polyvinylidene fluoride sheath, the corrosion resistance and scraped finish resistance performance of the cable are better, the flexibility is better, and the transverse and mechanical pressure resistance is enhanced; the polyvinylidene fluoride sheath is combined and connected with a polyolefin insulation layer, the electrical performance of the cable is more stable, the temperature resistance range of the cable is wide, and the service life of the cable is long.
