Base the above, described conductor wire core is closed and is formed by many soft copper skein silks.
The relative prior art of the utility model has substantive distinguishing features and progress, specifically, in the utility model, described conductor wire core is surrounded with the refractory insulating layer consisting of synthetic mica tape outward, because synthetic mica tape thermal endurance class is high, can reach the fire-resistant level of A level (950～1000 ℃), make this refractory insulating layer there is good fire protecting performance; Described refractory insulating layer is wrapped with the flame retardant insulation of being made by fluoro-46 materials, because fluoro-46 Maximum CW lasing temperatures can reach 200 degree, short time serviceability temperature can reach 260 degree, and oxygen index is greater than 95, combustion, makes this flame retardant insulation have good fire protecting performance hardly; Described flame retardant insulation is arranged with metal sheath outward, can play to cable the effect of shielding and protection; Described metal sheath is wrapped with the heat-insulating flame-retardant layer consisting of basalt fibre, because basalt fibre has low, high temperature resistant, the fire-retardant feature of conductive coefficient, make this heat-insulating flame-retardant layer not only there is good resistance to elevated temperatures, also there is good heat-proof quality; Described heat-insulating flame-retardant layer is wrapped with oversheath, whole cable is carried out to the protection of the first step, and generally speaking, each layer of cable arranges rationally, makes whole cable possess stronger fire protecting performance.
Further, in refractory insulating layer, the rate of putting up of synthetic mica tape is 17%～23%, makes this refractory insulating layer in range of application, reaching best fire protecting performance.
Further, described metal sheath is seamless heat-resisting aluminium alloy sheath, there is bellows-shaped, because heat-resisting aluminium alloy is high temperature resistant, intensity is large, make this metal sheath possess certain fire protecting performance, in addition, setting that aluminum alloy sheath is seamless, make the good airproof performance of whole cable, do not have gap, effectively stop moisture to enter cable inner and along the longitudinal flow of cable; Adopt undulatory structure can increase the flexibility of cable.
Further, described oversheath consists of ceramic silicon rubber, due to ceramic silicon rubber be a kind of novel polymer composite, the 750 ℃ * 90min flame ablation in the situation that, can form hard ceramic-like shell, and temperature is higher, burn to such an extent that the time is longer, housing is harder, and this housing can play the effect of good insulation, fire prevention and fire insulation.
Further, conductor wire core is closed and is formed by many soft copper skein silks, makes cable have better flexibility.
In sum, this flexible fire-proof cable has advantages of that design science, fire protecting performance are good, flexible, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of flexible fire-proof cable in the utility model.
In figure: 1. conductor wire core; 2. refractory insulating layer; 3. flame retardant insulation; 4. metal sheath; 5. heat-insulating flame-retardant layer; 6. outer jacket.
Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
Embodiment
As shown in Figure 1, a kind of flexible fire-proof cable, comprises by many soft copper skein silks and closes the conductor wire core 1 forming, and makes conductor wire core 1 have good flexibility.
The outer refractory insulating layer 2 being formed by synthetic mica tape that is surrounded with of described conductor wire core 1, the rate of putting up of described synthetic mica tape is 17%～23%, because the main feature of synthetic mica tape is that thermal endurance class is high, can reach the fire-resistant level of A level (950～1000 ℃), synthetic mica tape heat resisting temperature is greater than 1000 ℃ conventionally, make refractory insulating layer 2 there is good fire protecting performance, in addition, thickness range is at 0.08～0.15mm, maximum supply width 900mm, and the characteristic with natural mica band: the coefficient of expansion is little, dielectric strength is large, resistivity is high and dielectric constant is even, can effectively protect cable, further improve the performance of cable.
Described refractory insulating layer 2 is wrapped with the flame retardant insulation 3 of being made by fluoro-46 materials, owing to fluoro-46 being abbreviations of perfluoroethylene-propylene, be called again FEP, a kind of fluoroplastics of excellent performance, Maximum CW lasing temperature can reach 200 degree, and short time serviceability temperature can reach 260 degree, and oxygen index is greater than 95, combustion, makes this flame retardant insulation 3 have good fire protecting performance hardly; In addition; fluoro-46 have good weatherability; coefficient of friction is less; stable chemical performance, has good electrical insulation capability, and dielectric constant is little; dielectric loss angle tangent is low; electrical property does not almost change in quite wide range of temperature, makes its stable insulation, protection cable that can be good.
The outer metal sheath 4 that is arranged with seamless heat-resisting aluminium alloy sheath formation of described flame retardant insulation 3, because heat-resisting aluminium alloy has the advantages such as high temperature resistant, density is little, intensity is large, make this metal sheath 4 possess certain fire protecting performance, simultaneously, heat-resisting aluminium alloy also has good electric conductivity and mechanical performance, can play to conductor wire core the effect of shielding and protection; In addition, setting that aluminum alloy sheath is seamless, makes the good airproof performance of whole cable, does not have gap, effectively stops moisture to enter cable inner and along the longitudinal flow of cable; Adopt undulatory structure can increase the flexibility of cable.
Described metal sheath 4 is wrapped with the heat-insulating flame-retardant layer 5 consisting of basalt fibre, because basalt fibre has advantages of that conductive coefficient is low, high temperature resistant, fire-retardant, not only improved the resistance to elevated temperatures of whole cable, and prevented that outside heat from entering inside, make that these heat-insulating flame-retardant layer 5 resistances to elevated temperatures are good, effect of heat insulation is outstanding.
Described heat-insulating flame-retardant layer 5 is wrapped with the oversheath 6 consisting of ceramic silicon rubber, because ceramic silicon rubber is a kind of novel polymer composite, the in the situation that of 750 ℃ * 90min flame ablation, can form hard ceramic-like shell, and temperature is higher, burn to such an extent that the time is longer, housing is harder, this housing can play good insulation, the effect of fire prevention and fire insulation, in addition, ceramic silicon rubber can stand certain spray and percussion, and excellent electrical properties, satisfactory mechanical property, as outer jacket 6, not only play good insulation fireproofing function, and make the performance of cable each side all have lifting.
In sum, this cable rational in infrastructure, each layer all has good fire protecting performance, makes the fire protecting performance of whole cable outstanding; Conductor wire core 1 adopts the material that soft copper skein silk closes, fire-resistant aluminum alloy sleeve is set to bellows-shaped and other each layers adopt all to make this cable have good flexibility; Each layer also has excellent electric property, physical property etc., and greatly extended the useful life of this cable.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characterictic is equal to replacement embodiment of the present utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
