Description
Technical field
The invention belongs to electric wire field, in particular to a kind of shell-less fire resistant low-voltage cable.
Background technology
With the development of China's economic and Process of Urbanization Construction, urban distribution network system has seemed especially crowded, and a large amount of cables are handed over
Mistake is crisscrossed in urban distribution network, and because cable laying space is limited, substantial amounts of cable laying together, proposes to the safety of power network
Higher requirement, the especially protection to power network fire are increasingly taken seriously.The fire protection measure of common cable has two
Kind, when using fire-proof cable bridge rack, fire prevention bag or fire prevention channel, but the measure causes cable heat dispersion to be deteriorated, thermal resistivity
Improve, current-carrying capacity reduces；Second, use fire safe type cable, wrapped mica tape is as flame retardant coating outside conductor for the cable, but this is arranged
Apply and only can guarantee that cable short-duration power, cable in burning still need to scrap the cable more renewed after combustion, can not be exhausted in cable
It is continuing with after being repaired in the case that edge and conductor are intact, therefore adds secondary Meteorological.The usual section very little of conductor, from
Load-carrying properties are poor, and especially in use, because load-carrying properties are poor under not buried operating mode, cable own wt can cause cable
Cable conductor is broken, while also easily damages tiny cable conductor when in construction.Anti-interference is poor, is conveyed in itself when cable
When containing higher harmonic components in electric current, cable can produce electromagnetic interference to the electronic equipment around it；Conversely, extraneous electromagnetism
Interference can also be coupled on cable core, pair various electrically generation electromagnetic interferences to connect with cable.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of shell-less fire resistant low-voltage cable.
A kind of shell-less fire resistant low-voltage cable of the present invention, including garland formula core, in garland formula core
Outer overlapping wrapped low-smoke bittern-free highly fire-proof binding tape, extrudes copper strip shielding layer, in copper strips outside low-smoke bittern-free highly fire-proof binding tape
The fireprotection layer that three layers of flameproof fabric overlap is extruded outside screen layer, the plastic bellows of high temperature resistant is cased with outside fireprotection layer；It is described
Garland formula refractory ceramics of the garland formula core by four round insulation cores and co-extrusion outside four round insulation cores
Pipe is formed；The center of described refractory ceramics pipe is provided with heat emission hole.
Described insulated wire cores are made up of aluminium conductor and the high-temperature resistant rubber insulating barrier being extruded in outside aluminium conductor.
Described heat emission hole is rhombus, circle or square.
The beneficial effects of the present invention are：
1st, the present invention has very strong from load-carrying properties, changes more original core twisted synthesizing cable cored structures so that cable
Stress point concentrate on single line core, be not easily broken；
2nd, the present invention wrapped low-smoke bittern-free highly fire-proof binding tape overlapping outside garland formula core, not only cause cable that there is fire resisting resistance
Combustion type, the irregular space of core preferably is filled with, also secures core and be not easy to change；
3rd, the present invention is provided with copper strip shielding layer, can make shielding line and use and be used as the neutral conductor or ground wire, suitable for exchanging volume
Determine voltage 0.6/1kV and the anti-power transmission compared with strong electromagnetic, thunderbolt environment claimed below, enhance the anti-interference of cable
Property, extraneous electromagnetic interference are also not coupled on cable core, and pair various electromagnetism that will not electrically produce to connect with cable are done
Disturb；
4th, flameproof fabric and the plastic bellows of high temperature resistant are externally provided with cable of the present invention so that fireproofing of cable has reached optimality
Can, the plastic bellows of high temperature resistant has the property such as high tenacity, high-impact, good bending property, high-temperature resistant, acidproof, lubricating oil, coolant
Can, it is resistant to chemical etching, fire-retardant, the weight that pin is stepped on can be born, it is not broken, it is indeformable, can recover rapidly, and itself without appoint
What is damaged.
5th, provided with garland formula refractory ceramics pipe, heat-resisting quantity and impact resistance, there is good toughness, resistance to mechanical again
Thermal shock resistance properties is excellent, and is provided with heat emission hole at the center of earthenware, greatly reduces the temperature in core.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment：
As shown in figure 1, a kind of shell-less fire resistant low-voltage cable of the present invention, including garland formula core, in garland
Overlapping wrapped low-smoke bittern-free highly fire-proof binding tape 5, extrudes copper strip shielding layer outside low-smoke bittern-free highly fire-proof binding tape outside formula core
6, the fireprotection layer 7 that three layers of flameproof fabric overlap is extruded outside copper strip shielding layer, the plastic ripple of high temperature resistant is cased with outside fireprotection layer
Line pipe 8；Garland formula of the described garland formula core by four round insulation cores and co-extrusion outside four round insulation cores
Refractory ceramics pipe 3 is formed；Described insulated wire cores are by aluminium conductor 1 and the high-temperature resistant rubber insulating barrier being extruded in outside aluminium conductor
2 are formed.The center of described refractory ceramics pipe is provided with heat emission hole 4, and the heat emission hole is rhombus, circle or square.
The invention provides the form and implementation of shell-less fire resistant low-voltage cable, described above is only this hair
Bright is preferable to carry out method, it is noted that for those skilled in the art, is not departing from the principle of the invention
On the premise of, some improvement can also be made, these improvement also should be regarded as protection scope of the present invention.
