Anaerobic circular copper wires are used as conductors by the utility model, fire-resistant insulation layers with favorable shell-forming performance through high-temperature endless vulcanization are extruded on surfaces of the conductors, the fire-resistant insulation layers are made of elastomer insulating materials, a plurality of conductors with the fire-resistant insulation layers are strapped by strapping tapes of non-alkali glass silk to compose cores, and a plurality of cores are lapped by double-layer of polyester wrapping tapes to compose a cable core. An aluminum-plastic composite tape is longitudinally wrapped on the cable core to compose a shielding layer, and a fire-resistant, non-halogen and low-smoke oversheath adopting irradiation graft is arranged on the shielding layer formed by longitudinally wrapping the aluminum-plastic composite tape. The utility model has the advantages of reasonable and simple structure, easy production manufacture and good service performance. The utility model has high electric property, good fire resistant property and anti-electromagnetic interference ability and stable signal-transmission property. The utility model is used for urban railway traffic, and signal and voice communication is still kept under the condition of fires, which is favorable for fire-fighting command and personnel evacuation, and personnel and property loss is decreased.
Description
Technical field
The utility model relates to the structure of cable, belongs to the cable technology field.
Background technology
Existing signal cable all is insulating material with the polyethylene, is sheath material with polyvinyl chloride or polyolefin, and whole cable technology does not have any fireproof construction, and therefore existing signal cable does not have fire resistance.The normal signal cable is used in the urban track traffic environment, in case catch fire in the space of sealing, cable will be easy to by scaling loss, destroys, and can not play guaranteeing role to signals security transmission and device security.Along with the development of society, the quantity of track traffic and the speed of orbital motion develop rapidly and improve, and the fire resistance of cable is along with development of urban rail traffic seems more and more important.Use common cable in the railway traffic engineering, in case breaking out of fire causes very big loss all for easily the people's life and property.
The utility model content
The purpose of this utility model is exactly the loss that is brought for the low fire of safety and health that improves urban track traffic, develops a kind of fire resistance signal cable.
The purpose of this utility model is to realize like this, fire resistance signal cable, the insulating barrier and the oversheath that comprise conductor, conductive surface, it is characterized in that the many conductors that are provided with insulating barrier are tied up with the alkali-free glass wool band constitutes one group of core, many group cores are provided with the aluminium-plastic tape screen with the wrapped formation cable core of double-deck polyester band between cable core and oversheath.Described conductor is an anaerobic round copper wire conductor.Described insulating barrier is the refractory insulating layer that can good elastic body insulated material extrudes through the shelling of high temperature continuous vulcanization.The described many conductors that are provided with insulating barrier tie up with the alkali-free glass wool band that to constitute one group of core be the conductor that is provided with insulating barrier more than three.Described aluminium-plastic tape screen is an aluminum plastic composite belt longitudinal bag screen.Described oversheath is for adopting the sheath of the fire-retardant LSOH anti-flaming of irradiation grafting.
This cable is the fire resistance signal cable of a kind of environmental protection, fire protection flame retarding and Electro Magnetic Compatibility, in rugged environment, in case the transmission signals ability of catching fire and can keep 90 minutes does not discharge toxic gas simultaneously, smoke density is lower during burning, for fire-fighting work brings convenience.Be used for urban track traffic, can remain on still inhibit signal and voice communication under the situation of fire, this will bring the most correct and approach the most fast to fire-fighting command and evacuating personnel, great help will be provided for relief and fire-fighting work, thus minimizing attack time and minimizing personnel and property loss.
The utility model is rational in infrastructure simple, manufactures easily, and serviceability is good.Conductor adopts the anaerobic round copper wire, and the transmission performance of cable is stable; Insulation system adopts elastic body insulated, and it has high electrical property and good fire resistance energy; The wrapped double-deck polyester band of cable core is guaranteed the rounding property of cable; The aluminium-plastic tape screen improves the anti-electromagnetic interference capability of cable, and becomes the shell rate in the increase of cable fire process, guarantees the cable fire resistance; Adopt the irradiation grafting low smoke, zero halogen to hinder right oversheath, can further reduce the amount of being fuming and reduce flame-retarding power, improve cable life and mechanical strength.
Description of drawings
Figure 1 shows that structural representation of the present utility model, among the figure: 1 conductor, 2 insulating barriers, 3 alkali-free glass wool bands, 4 polyester bands, 5 screens, 6 oversheaths.
Embodiment
To adopt the anaerobic round copper wire be conductor 1, extrude the refractory insulating layer 2 of the elastic body insulated material that shelling through the high temperature continuous vulcanization can be good at conductive surface.Four conductors that are provided with refractory insulating layer are tied up with alkali-free glass wool band 3 and are constituted one group of core, and four groups of cores are with double-deck polyester band 4 wrapped formation cable cores.On cable core, adopt the aluminum plastic composite belt longitudinal bag to constitute screen 5.The oversheath 6 of the fire-retardant LSOH anti-flaming that adopts irradiation grafting is set on aluminum plastic composite belt longitudinal bag screen.
Claims (6)
1, a kind of fire resistance signal cable, the insulating barrier and the oversheath that comprise conductor, conductive surface, it is characterized in that the many conductors that are provided with insulating barrier are tied up with the alkali-free glass wool band constitutes one group of core, many group cores are provided with the aluminium-plastic tape screen with the wrapped formation cable core of double-deck polyester band between cable core and oversheath.
2, fire resistance signal cable according to claim 1 is characterized in that described conductor is an anaerobic round copper wire conductor.
3, fire resistance signal cable according to claim 1 is characterized in that described insulating barrier is the refractory insulating layer that can good elastic body insulated material extrudes through the shelling of high temperature continuous vulcanization.
