Preferably, described sub-line and described fixed frame, protective sleeve laminating.
Preferably, the center superposition of the center of the cross section of steel wire rope and the cross section of described cable core, described sub-wire loop is uniformly distributed around protective sleeve outside.
Preferably, the pipeline that metallic support is hollow, metal support surface has multiple micropores, and obturator is packed in micropore, and extinguish material is filled in metallic support.
Preferably, the pressure in metallic support is greater than atmospheric pressure.The obturator fusing point of wherein selecting is lower than the fusing point of extinguishing pipe.
Preferably, insulating barrier adopts smokeless halogen-free cross-linking radiation oil resistant TPE material to make.
Preferably, the pressure in extinguishing pipe is greater than atmospheric pressure.
The utility model provides a kind of thermal resistance cable, simple in structure, compact and reasonable, utilize inner extinguishing pipe and metallic support to form a fixed frame, sub-line is fixed on and in framework, is difficult for sideslip, but also strengthened the intensity of whole cable, make cable be difficult for excessive complications and cause disconnected core; Owing to there being steel wire rope in cable core, improve the tensile property of whole cable, also can make cable not cause disconnected core because of excessive complications; Filler is glass fiber, has adopted glass fiber as filler, has high temperature resistant and characteristic fire resistance, has improved interference free performance and the insulation property of cable, and anti-corona performance is good; The content of extinguishing pipe is fire proofing, when cable powering is excessive or cable ambient temperature is too high, while exceeding the fusing point of extinguishing pipe, illustrates that this cable is dangerous, and extinguishing pipe melts and discharges fire proofing, reaches the fire-retardant effect of thermal resistance.
Brief description of the drawings
Fig. 1 is the cross-sectional structure schematic diagram of a kind of flame retardant cable that the utility model proposes.
Embodiment
Below, by specific embodiment, technical scheme of the present invention is elaborated.
With reference to Fig. 1, a kind of thermal resistance cable, comprise cable core, the screen 5 of coated described cable core, the oversheath 6 of coated screen 5, described cable core comprises at least one root line, at least three extinguishing pipes 7, at least steel cable 9 and filler 4, described sub-line comprises the insulating barrier 2 of conductor 1 and coating conductor 1, particularly, insulating barrier 2 adopts smokeless halogen-free cross-linking radiation oil resistant TPE material to make, when cable burns, because adopting smokeless halogen-free cross-linking radiation oil resistant TPE material, makes insulating barrier 2, can not produce poisonous and hazardous gas, thereby can not produce harm to human body and environment, fire proofing 3 is filled in extinguishing pipe 7, particularly, pressure in extinguishing pipe 7 is greater than atmospheric pressure, under state at ordinary times, fire proofing 3 is compressed in extinguishing pipe 7, in the time that temperature rising exceedes the fusing point of extinguishing pipe 7, extinguishing pipe 7 melts, because the pressure in extinguishing pipe 7 is greater than atmospheric pressure, fire proofing 3 is ejected, reach the effect of quick extinguishing, protective sleeve 10 is coated on steel wire rope 9 outsides, filler 4 is glass fiber, extinguishing pipe 7 outer wall laminating screen 5 inwalls, and be uniformly distributed around screen 5 inner sides, between adjacent two extinguishing pipes 7, adopt metallic support 8 to be fixedly connected with, extinguishing pipe 7 and metallic support 8 form a fixed frame, described sub-line is fixed in described fixed frame, particularly, described sub-line and described fixed frame, protective sleeve 10 is fitted, sub-line is played a supporting role for extinguishing pipe 7 and metallic support 8, and extinguishing pipe 7 and metallic support 8 antithetical phrase line extruding are fixing, make the whole construction of cable compacter, further, the center superposition of the center of the cross section of steel wire rope 9 and the cross section of described cable core, described sub-wire loop is uniformly distributed around protective sleeve 10 outsides, make cable internal structure stable, structure is simpler, compact and reasonable, filler 4 is filled described sub-line, extinguishing pipe 7 and metallic support 8 gap around.
In specific embodiment, the pipeline that metallic support 8 is hollow, there are multiple micropores 11 on metallic support 8 surfaces, obturator is packed in micropore 11, extinguish material is filled in metallic support 8, in the time that temperature rising exceedes the fusing point of obturator, obturator fusing, discharge extinguish material, with the collaborative fire extinguishing cooling of fire proofing 3, further, pressure in metallic support 8 is greater than atmospheric pressure, the fusing point of the obturator of selecting is lower than the fusing point of extinguishing pipe 7, under state at ordinary times, extinguish material is compressed in metallic support 8, when temperature raises, obturator first melts, because the pressure in metallic support 8 is greater than atmospheric pressure, extinguish material is ejected, reach the effect of fast cooling and fire extinguishing, when extinguish material is effectively when fire extinguishing cooling, temperature further raises, exceed the fusing point of extinguishing pipe 7, extinguishing pipe 7 then discharges fire proofing 3 and puts out a fire.
The utility model provides a kind of thermal resistance cable, simple in structure, compact and reasonable, utilize inner extinguishing pipe and metallic support to form a fixed frame, sub-line is fixed on and in framework, is difficult for sideslip, but also strengthened the intensity of whole cable, make cable be difficult for excessive complications and cause disconnected core; Owing to there being steel wire rope in cable core, improve the tensile property of whole cable, also can make cable not cause disconnected core because of excessive complications; Filler is glass fiber, has adopted glass fiber as filler, has high temperature resistant and characteristic fire resistance, has improved interference free performance and the insulation property of cable, and anti-corona performance is good; The content of extinguishing pipe is fire proofing, when cable powering is excessive or cable ambient temperature is too high, while exceeding the fusing point of extinguishing pipe, illustrates that this cable is dangerous, and extinguishing pipe melts and discharges fire proofing, reaches the fire-retardant effect of thermal resistance.
