Abstract
The utility model discloses a kind of low smoke halogen-free fire retardant fire resistant flexible cable peculiar to vessel, include conductor, conductor is the stranded flexible conductor of zinc-plated oxygen-free copper the 5th class, be coated with successively low-smoke non-halogen flame-retardant ceramic silicon rubber flame retardant coating and ethylene propylene rubber insulated layer in the outside of conductor, will after many conductor bundle strands, be coated with successively tension lapping layer, inner sheath, tinned copper wire woven shield and oversheath in outside.The utlity model has and can extrude continuously, high-low temperature resistant, soft, moistureproof advantage does not absorb water, overcome the shortcoming losing efficacy after ordinary mica tape water suction, overcome the shortcoming that mica tape cannot wrapped small bore flexible conductor, overcome ethylene-propylene rubber and adopt squash type easily to squeeze the feature of fractus master tape, overcome mica tape and be difficult for wrapped smooth, even subsides, tight, wrinkling and frangible shortcoming; Out-of-flatness while having overcome on conductor wrapped Mica tape, heterogeneity, flexible conductor, because monofilament is tiny, is difficult for by the phenomenon of fire resistance test because monofilament easily blows after wrapped mica tape.
Description
Technical field
The utility model relates to cable technology field, relates in particular to a kind of low smoke halogen-free fire retardant fire resistant flexible cable peculiar to vessel.
Background technology
Present low smoke halogen-free fire retardant fire resistant flexible cable peculiar to vessel is all wrapped cloud bar on conductor substantially, in the time of Mica tape, the cross section of conductor is little, must use special-purpose fire-resistant lapping equipment, when wrapped, also exist be difficult for wrapped smooth, even subsides, closely, adding mica is a kind of fragility material, walk around in journey the careless slightly mica that will cause wrinkling and broken, cause ND spark to hit ignore, for the safe handling of cable later causes great hidden danger, and cable also cannot be by the fire resistance test of national Specification, because cross-sectional area of conductor is less and soft, employing ordinary mica tape is wrapped, even if adopting special-purpose fire-resistant lapping equipment is also to produce, the situation that this just causes fire-resistant cable with small cross section to produce.Get on even wrapped, when the face use aboard ship of its cable, due to salt fog and moisture larger, mica tape is in the time running into salt fog and moisture, its insulation property can variation, even there is no insulation property, make the fire-resistant disabler of cable, adopt this extrusion type refractory insulation material just can overcome these production bottlenecks, and the flame retardant coating of extruding is after sulfuration, have advantages of soft, wear-resisting, do not absorb water, and can be by the fire resistance test of national regulation.
Utility model content
The utility model object is exactly the defect in order to make up prior art, and a kind of low smoke halogen-free fire retardant fire resistant flexible cable peculiar to vessel is provided.
The utility model is achieved through the following technical solutions:
A kind of low smoke halogen-free fire retardant fire resistant flexible cable peculiar to vessel, include conductor, described conductor is the stranded flexible conductor of zinc-plated oxygen-free copper the 5th class, be coated with successively low-smoke non-halogen flame-retardant ceramic silicon rubber flame retardant coating and ethylene propylene rubber insulated layer in the outside of conductor, will after many conductor bundle strands, be coated with successively tension lapping layer, inner sheath, tinned copper wire woven shield and oversheath in outside.
Described inner sheath and oversheath all adopt the rubber sheath taking EVM as base-material.
Conductor is to adopt the stranded flexible conductor of zinc-plated oxygen-free copper the 5th class, to improve flexibility and the bending property of cable, adopts tinned conductor to improve anti-seawater and the salt air corrosion of cable.
What flame retardant coating adopted is low-smoke non-halogen flame-retardant ceramic silicon rubber, and it is high that this refractory material has heatproof, good insulation preformance, and water resistant and humidity resistance are high, and wet did not lose efficacy, non-friable, can extrude continuously and characteristic convenient for production.
What insulating barrier adopted is the ethylene propylene rubber insulated of environment-friendly tasteless, and this insulation adopts the sulfuration of tasteless vulcanizing agent, has environmental protection, tasteless, good insulation preformance, resistance to water and salt spray resistance good characteristic.
The elastomeric material taking EVM as base-material that sheath adopts, and adopt tasteless vulcanizing agent to vulcanize, it is high that this material has oxygen index, and fire resistance is good, and low smoke and zero halogen performance is good, softness, resistant to hydrolysis performance is high, wear-resisting, the characteristic of salt spray resistance.
The tinned copper wire braid shielded that screen adopts, adopts tinned copper wire braid shielded, and cable has the characteristic that corrosion resistance is good, also can improve the shielding properties of cable simultaneously.
The utility model has the advantages that: the utlity model has and can extrude continuously, high-low temperature resistant, soft, moistureproof advantage does not absorb water, overcome the shortcoming losing efficacy after ordinary mica tape water suction, more the more important is to have overcome the shortcoming that mica tape cannot wrapped small bore flexible conductor, overcomes ethylene-propylene rubber and adopts squash type easily to squeeze the feature of fractus master tape, overcome mica tape and be difficult for wrapped smooth, even subsides, tight, wrinkling and frangible shortcoming; Out-of-flatness while having overcome on conductor wrapped Mica tape, heterogeneity, flexible conductor, because monofilament is tiny, is difficult for by the phenomenon of fire resistance test because monofilament easily blows after wrapped mica tape; Install and do not have penetrating odor generation aboard ship, greatly improved the environment friendly of cable, adopt salt spray resistance sheath material greatly to improve the decay resistance of cable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
