Description
Technical field
The utility model relates to field of cables, particularly relates to a kind of resistance to compression flame-proof power cable.
Background technology
At present, along with socioeconomic development, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as in aviation, the cable used in the fields such as electric power, high all especially to the requirement of the high pressure resistant and diamagnetic jamming performance aspect of cable, but now used on the market cable is because its structural design is unreasonable or the problem such as material, effective protective effect can not be played, cable is when breaking out of fire, material can not play good fireproofing function, cause cable covering damaged, be easy to make people that the situation of getting an electric shock occur, fire is made to cause larger disaster, if the incomplete words that cable possesses, normal work and the safety of staff can be affected.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of resistance to compression flame-proof power cable.
The utility model is taked following technical scheme to realize: a kind of resistance to compression flame-proof power cable, and it comprises cable body, conductor, packed layer, insulating barrier and screen, and the cross section of described cable body is circular configuration; And be provided with many conductors in described cable body; Described conductor is evenly arranged into two row; Described conductor sizes is identical; Gap portion between described conductor and insulating barrier is provided with packed layer; Described conductor closely extrudes a layer insulating; One deck screen is extruded outside described insulating barrier; Described screen is closely extruded with armour and flame-retardant layer from inside to outside successively; Described flame-retardant layer inside is provided with many guide cores; Described flame-retardant layer is extruded with inner sheath and oversheath from inside to outside successively.
Above-mentioned a kind of resistance to compression flame-proof power cable, described conductor forms by multiply tinned copper wire is stranded.
Above-mentioned a kind of resistance to compression flame-proof power cable, described flame-retardant layer is Phos fire retardant glue.
Above-mentioned a kind of resistance to compression flame-proof power cable, described inner sheath and jacket material are that anticorrosion butyronitrile elastomeric material is formed.
Above-mentioned a kind of resistance to compression flame-proof power cable, described insulating barrier is made up of ceramic SiClx insulating material.
Above-mentioned a kind of resistance to compression flame-proof power cable, the square grid shape structure that the packed layer that the gap portion between described conductor and insulating barrier is arranged is woven by stainless steel wire.
The utility model has following beneficial effect in sum: this cable has good shielding properties, resist bending performance, conductance is high, also there is the performances such as high pressure resistant simultaneously, described conductor forms by multiply tinned copper wire is stranded, not only substantially increases the operating efficiency of cable, also make its work more stable, and described conductor structure is easy to processing, making length is unrestricted, has certain flexibility and bendability during use, facilitates the laying of workpeople.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, cable body; 2, conductor; 3, packed layer; 4, insulating barrier; 5, screen; 6, guide core; 7, armour; 8, flame-retardant layer; 9, inner sheath; 10, oversheath.
Embodiment
As shown in Figure 1, a kind of resistance to compression flame-proof power cable, it comprises cable body 1, conductor 2, packed layer 3, insulating barrier 4 and screen 5, and the cross section of described cable body 1 is circular configuration; And be provided with many conductors 2 in described cable body 1; Described conductor 2 is evenly arranged into two row; Described conductor 2 size is identical; Gap portion between described conductor 2 and insulating barrier 4 is provided with packed layer 3; Described conductor 2 closely extrudes a layer insulating 4; One deck screen 5 is extruded outside described insulating barrier 4; Described screen 5 is closely extruded with armour 7 and flame-retardant layer 8 from inside to outside successively; Described flame-retardant layer 8 inside is provided with many guide cores 6; Described flame-retardant layer 8 is extruded with inner sheath 9 and oversheath 10 from inside to outside successively.
Described conductor 2 adopts that multiply tinned copper wire is stranded to be formed, and not only substantially increases the operating efficiency of cable, also makes its work more stable, and described conductor 2 structure is easy to processing, making length is unrestricted, has certain flexibility and bendability during use, facilitates the laying of workpeople; The packed layer 3 arranged between described conductor 2 and insulating barrier 4 is the square grid shape structures woven by stainless steel wire, substantially increase the working strength of cable body 1, make cable body 1 can bear larger pressure, effectively extend the useful life of cable body 1; The insulating barrier 4 extruded outside described conductor 2 is made up of ceramic SiClx insulating material, when cable breaking out of fire, the insulating barrier 4 meeting ceramic immediately that temperature raises, the pottery formed has good insulating properties and heat resistance, even if concrete on fire also can continue to use, without the need to changing, thus greatly save cost; The screen 5 extruded outside described insulating barrier 4 effectively raises the shielding properties of cable body 1, avoids the interference of signal, makes it use more stable; The outer armour 7 arranged of described screen 5 effectively can improve the structural stability of cable body 1, the ability making it bear high pressure and distortion power is stronger, the outer flame-retardant layer 8 arranged of described armour 7 adopts Phos fire retardant glue to make, there is good high temperature resistant and fire-retardant effect, cable also normally can be worked in the case of a high temperature, can effectively protect cable inner conductor to be damaged; The guide core 6 arranged in described flame-retardant layer 8 improves the grounding of cable body 1, makes it use safer; Described inner sheath 9 and oversheath 10 are that anticorrosion butyronitrile elastomeric material is formed, not only there is fire performance, and cable is nonflammable when fire, and can stop burning after flame spread the expansion with disaster, the smog produced during cable fire is also very thin, is conducive to the evacuation of personnel and the carrying out of fire-fighting work.
The above is the utility model embodiment, therefore all equivalences done according to structure, feature and the principle described in the utility model application range change or modify, and are included in the utility model patent claim.
