Abstract
The utility model discloses a control cable for a flame-retardant ship. The control cable comprises a plurality of conductors and insulating layers, wherein the outer sides of the conductors are coated with insulating layers and branch shielding layers in sequence respectively; the conductors coated with the insulating layers and the branch shielding layers are twisted into bundles; the outer sides of the branch shielding layers are coated with taped coverings after being bundles; a plurality of longitudinal filling ropes are arranged between the taped coverings and the branch shielding layers; the outer sides of the taped coverings are provided with total shielding layers, jacket layers and armor layers in sequence; the conductors are tin-plated copper wires with the resistivity of less than 0.017241 ohm.mm<2>/m (20 DEG C); the branch shielding layers and the total shielding layers are woven by copper wires; and the jacket layers are made from flame-retardant polyolefin. In the utility model, columnar filling ropes are arranged, so that the tensile strength is enhanced; and meanwhile, due to the adoption of two layers of the shielding layers, the shielding efficiency is improved effectively.
Description
Technical field:
The utility model relates to control cable peculiar to vessel field, relates in particular to a kind of fire-retardant control cable peculiar to vessel.
Background technology:
Cable is in order to transmit electricity (magnetic) energy, the wire product of information and the conversion of realization electromagnetic energy.
Shipboard cable comprises that ship power cable, control cable peculiar to vessel, cable for telecommunication of ships, naval vessel are with control cable etc.Mainly be applicable to transmission of aquatic building thing and electrical equipment control such as various rivers seagoing vessel oceangoing ship and offshore oil platform.
Traditional control cable peculiar to vessel has armour mostly as required, strengthen cable intensity except having, exempt from the effect that mechanical damage and mouse are bitten for the armature of cable layer, also because mostly armoring material is that, steel wire wrapped by the steel band of high permeability or copper wire braiding constitute, this antagonism low-frequency disturbance is very useful, by proper grounding to armour, can also improve the lightning protection properties of cable, the benefit that armoured cable brings to construction be exactly need not special cable trough can direct-burried, the corner also need not to build in addition cable shaft.Sometimes only has the strength demand that armour also is not enough to satisfy cable.
The utility model has strengthened tensile strength at the gasket for packing that has increased column; Simultaneously, adopt two-layer screen to effectively raise shield effectiveness.In addition, insulating layer material adopts cross-linked polyolefin, and insulation property are superior, the restrictive coating material adopts flame-proof polyvinyl chloride, fire resistance halogen gas, gas pH value of water solution and conductivity good, that overflow when burning is low, has the low-corrosiveness energy, and it is few to generate smog during cable fire.
The utility model content:
The purpose of this utility model provides a kind of fire-retardant control cable peculiar to vessel, has mainly solved the intensity of traditional cable, the defective that shielding properties is not enough to practical requirement.
The technical solution of the utility model is as follows:
Fire-retardant control cable peculiar to vessel, comprise several conductors, insulating barrier, the outside of described several conductors is enclosed with insulating barrier, sub-shield respectively successively, it is characterized in that: the stranded bunchy of several conductors after wrap insulate layer, the sub-shield, behind the bunchy, the outside of described sub-shield is enclosed with lapping layer, is provided with several vertical gasket for packings of putting between described lapping layer and the described sub-shield, and the described lapping layer outside is enclosed with total screen, restrictive coating, armour successively.
Described fire-retardant control cable peculiar to vessel is characterized in that: described several conductors all adopt tinned copper wire, and the resistivity of described tinned copper wire is less than 0.017241
. mm
2/ m (20 ℃).
Described fire-retardant control cable peculiar to vessel is characterized in that: described sub-shield, total screen all adopt the copper wire braiding to constitute, and described restrictive coating material adopts fire retardant polyolefin.
The utility model has the advantages that:
The utility model has strengthened tensile strength at the gasket for packing that has increased column; Simultaneously, adopt two-layer screen to effectively raise shield effectiveness; In addition, the restrictive coating material adopts flame-proof polyvinyl chloride, and fire resistance halogen gas, gas pH value of water solution and conductivity good, that overflow when burning is low, has the low-corrosiveness energy, and it is few to generate smog during cable fire.
