Description
Technical field
The utility model belongs to power cable technical field, is specifically related to a kind of high fireproof power cable.
Background technology
Wires and cables industry be China only this in the second largest industry of automobile industry.Along with intelligent building, skyscraper, increase Deng crowded place, in the electric power system of these facilities, bring into use crosslinked polyetylene insulated fireproof power cable, owing to not possessing refractory ability along with common power cable with cross-linked polyethylene insulation, the stable operation of supply line can not be kept under flame, when breaking out of fire, cable can burn very soon, stops power supply.Along with the needs of the development of society, the quality requirement of electric wire is also improved constantly, the cable used in each field, to the fire resistance of cable and the requirement of pull resistance high especially.
Therefore, how improving fire resistance and tension, the crushing resistance of cable, is the current technical issues that need to address of those skilled in the art.
Summary of the invention
The utility model provides a kind of high fireproof power cable, has good fire resistance, anti-flammability and pull resistance, and reduces the harm caused environment.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of high fireproof power cable, comprise cable core and be coated on the protective jacket outside described cable core, described protective jacket is low smoke and zero halogen sheath, the first braid and the first fire-resistant isinglass belt is provided with from outside to inside successively between described protective jacket and cable core, described cable core is the conductor that some electric units are intertwined, and described electric unit comprises the second braid, the second fire-resistant isinglass belt and metal bare wire from outside to inside successively.
The utility model adopts the structure of double-deck fire-resistant isinglass belt and double glazing fiber braiding layer, makes electric wire have dual anti-flammability and pull resistance, and resistance to compression, the power supply being applicable to most of place uses.Employing duplex sheath designs, and double shielding makes electric wire have good radial water-resisting performance.Fire-resistant isinglass belt has good flame retardant effect, and cable can not be made to burn in flame; Fiberglass braided layer has good anti-flammability and pull resistance.Protective jacket adopts low smoke and zero halogen sheath, the insulating barrier of the electric unit that low smoke and zero halogen material is made can also be set up, make electric wire have low cigarette, Halogen, low toxicity and excellent fire resistance, avoid manufacture, use and waste treatment time produce the public hazards such as a large amount of dioxin, lead, halogen.
Preferably, twining package tape is provided with between described second braid and the second fire-resistant isinglass belt.Twining package tape adopt nonwoven fabrics make, moment heatproof can bear 230 ° non-fusible indeformable, cable nonwoven is furnished with good corrosion resistance, can resistance to sulfuration.
Preferably, between described cable core and the first fire-resistant isinglass belt, all packed layer is filled with between electric unit.
Preferably, described packed layer is polyester-cotton blend.Polyester-cotton blend better can fill the space between cable core, and inner structure is more compacted, even if be subject to extraneous extruding, cable also can remain unchanged shape, and it is high to have water absorption, the characteristic that water preventing ability is excellent.
Preferably, described first braid and the second braid are fiberglass braided layer.Fiberglass braided layer adopts high-temperature-resistant high type glass fibre, processes through special process.There is high temperature resistant, insulation, insulation, fire protection flame retarding, corrosion-resistant, ageing-resistant, the feature such as weatherability, high strength, smooth in appearance.Ensure that cable has better shielding action.
The utility model discloses a kind of high fireproof power cable, adopt the structure of double-deck fire-resistant isinglass belt and double glazing fiber braiding layer, electric wire is made to have dual anti-flammability, there is good fire resistance and anticorrosive property, also there is excellent pull resistance and crushing resistance, extend the useful life of cable.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the structural representation of a kind of high fireproof power cable of the utility model.
Embodiment
As shown in Figure 1, for the preferred embodiment 1 of a kind of high fireproof power cable of the utility model, comprise cable core and be coated on the protective jacket 8 outside described cable core, described protective jacket 8 is low smoke and zero halogen sheath, the first braid 1 and the first fire-resistant isinglass belt 7 is provided with from outside to inside successively between described protective jacket 8 and cable core, described cable core is the conductor that some electric units are intertwined, and described electric unit comprises the second braid 2, second fire-resistant isinglass belt 4 and metal bare wire 5 from outside to inside successively.Twining package tape 3 is provided with between described second braid 2 and the second fire-resistant isinglass belt 4.Described first braid 1 and the second braid 2 are fiberglass braided layer.
The utility model adopts the structure of double-deck fire-resistant isinglass belt and double glazing fiber braiding layer, makes electric wire have dual anti-flammability and pull resistance, and resistance to compression, the power supply being applicable to most of place uses.Employing duplex sheath designs, and double shielding makes electric wire have good radial water-resisting performance.Fire-resistant isinglass belt has good flame retardant effect, and cable can not be made to burn in flame; Fiberglass braided layer has good anti-flammability and pull resistance.Protective jacket adopts low smoke and zero halogen sheath, the insulating barrier of the electric unit that low smoke and zero halogen material is made can also be set up, make electric wire have low cigarette, Halogen, low toxicity and excellent fire resistance, avoid manufacture, use and waste treatment time produce the public hazards such as a large amount of dioxin, lead, halogen.Twining package tape 3 adopts nonwoven fabrics to make, moment heatproof can bear 230 ° non-fusible indeformable, cable nonwoven is furnished with good corrosion resistance, can resistance to sulfuration.
Between described cable core and the first fire-resistant isinglass belt 7, between electric unit, be all filled with packed layer 6.Described packed layer 6 is polyester-cotton blend.Polyester-cotton blend better can fill the space between cable core, and inner structure is more compacted, even if be subject to extraneous extruding, cable also can remain unchanged shape, and it is high to have water absorption, the characteristic that water preventing ability is excellent.
The foregoing is only specific embodiment of the utility model, but technical characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed among the scope of the claims of the present utility model.
