Abstract
The utility model discloses a kind of fireproof armored cable, comprise by the cable core of two insulated wire cores pair twists put side by side, gap in cable core is provided with packed layer, wrap up belting layer, metal armor layers, oversheath successively outward at cable core, described insulated wire cores is made up of the conductor of centre and the flame retardant coating be arranged on outside conductor and insulating barrier.Packed layer in the utility model is asbestos gasket for packing, this structure can play good refractory heat-insulating effect in a fire, also be provided with the flame retardant coating be made up of ceramic fireproof composite band in cable core, make the insulating barrier of cable be softened in a fire and not melt.Adopting armour afterwards, except bearing External Force Acting, also playing the effect of fire resistive construction in firm cable and fire insulation, even if impacted in work with in installing, also can not cause that the material of packed layer and belting layer is loose to be opened, ensure that the reliability of cable.
Description
Technical field
The utility model relates to a kind of power cable, specifically a kind of fireproof armored cable.
Background technology
Fire-resisting cable refers to the cable that can keep certain hour safe operation in flame combustion situation.Fire resistance test divides A, B two kinds of ranks by China's standard GB/T 12666.6, A level flame temperature 950 ~ 1000 DEG C, continues for fire time 90min, B level flame temperature 750 ~ 800 DEG C, continue for fire time 90 min, whole duration of test, sample should bear the load voltage value that product specifies.
Fire-resisting cable is widely used in the place relevant with fire safety and fire-extinguishing and lifesaving such as skyscraper, underground railway, undergrond street, large-scale power station and important industrial and mining enterprises.Outside existing fire-resisting cable employing conductor, wrapped mica brings and reaches fire-resistant effect, but cable often rocks the collision with junk with various in installation and work, mica tape flame retardant coating may be made to become lax, even dissipate, cause cable to lose original fire-resistant function.
Utility model content
Technical problem to be solved in the utility model is to provide the fireproof armored cable that a kind of fire resistance is excellent, mechanical structure is strong.
A kind of fireproof armored cable described in the utility model, comprise by the cable core of two insulated wire cores pair twists put side by side, the gap in cable core is provided with packed layer, at cable core outer wrapping belting layer, extrude oversheath outside belting layer, cable core outermost layer is braided metal armour also; Described insulated wire cores is made up of the copper conductor of centre and the flame retardant coating be arranged on outside conductor and insulating barrier.
As improvement, described packed layer is asbestos gasket for packing, and packed layer thickness is 1.0-2.0mm.
Further improvement, described belting layer is flame-retardant glass cloth band.
Improve further, described flame retardant coating is made up of ceramic fireproof composite band again.
The beneficial effects of the utility model are:
Packed layer in the utility model is asbestos gasket for packing, belting layer is flame-retardant glass cloth band, this structure can play good refractory heat-insulating effect in a fire, also be provided with the flame retardant coating be made up of ceramic fireproof composite band in cable core, make the insulating barrier of cable be softened in a fire and not melt.Adopting armour afterwards, except bearing External Force Acting, also playing the effect of fire resistive construction in firm cable and fire insulation, even if impacted in work with in installing, also can not cause that the material of packed layer and belting layer is loose to be opened, ensure that the reliability of cable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of fireproof armored cable of the present utility model, comprises by the cable core of two insulated wire cores pair twists put side by side, gap in cable core is provided with packed layer 4, at cable core outer wrapping belting layer 5, the outer wrapped metal armor layers 6 of belting layer 5, cable core outermost layer extrudes oversheath 7; Described insulated wire cores is made up of the copper conductor 1 of centre and the flame retardant coating 2 be arranged on outside conductor and insulating barrier 3.
Packed layer 4 described above is asbestos gasket for packing, and packed layer thickness is 1.0-2.0mm; Described belting layer 5 is flame-retardant glass cloth band; Described flame retardant coating 2 is made up of ceramic fireproof composite band.
The utility model provides a kind of fireproof armored cable version and implementation method; the above is only preferred implementation method of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
