Marine fire-resistant composite cable

Abstract

The invention discloses a marine fire-resistant composite cable, which comprises a cable core, wherein the cable core comprises a framework; the framework comprises a main framework having an equilateral triangle section and each of which has an equilateral triangle section; the middles of the three surfaces of the main framework are all axially slotted, and a sub-framework is arranged in each slot; two sections of the slot are respectively clamped on the central line of two surfaces of the corresponding sub-framework; the main framework and the three sub-frameworks are an integrated structure; a power cable core is respectively arranged on three corners of the main framework; a control cable core is respectively arranged in each sub-framework; and a crosslinked polyolefin inner sheath, atinned copper tape braided total shielding layer, and a crosslinked polyolefin outer sheath are orderly coated on the outer side of the cable core from the inside to the outside. The marine fire-resistant composite cable is provided with a framework; the framework comprises a main framework having an equilateral triangle section and three sub-frameworks having an equilateral triangle section; thestability of the triangle is used for providing a good protection for the control core and meanwhile increasing the compression resistance and pulling resistance of the cable.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a marine fire-resistant composite cable. Background technique [0002] my country has a long coastline and a vast sea area. The wires and cables used in the high-temperature environment on board have poor anti-interference ability, which may easily cause transmission signal disorder, and even cause casualties or property losses. The inner conductor of the traditional marine cable is a copper conductor, and the sheath is a single-layer PVC sheath. Most of the cables for ships and marine engineering now require the cables to be low-smoke, halogen-free, environmentally friendly, corrosion-resistant, fire-resistant, and water-resistant. , it is obvious that traditional marine cables can no longer meet the requirements of modern ships. Contents of the invention [0003] The object of the present invention is to provide a fire-resistant composite cable for ships in order to remedy th...
