Abstract
The utility model discloses a track traffic cable. Pluralities of insulation wire cores are twisted into a cable core, filling layers are arranged in clearances of the cable core, each insulation wire core consists of a conductor and an insulation layer form inside to outside, a waterproof tape, a low-smoke zero-halogen glass fiber tape, a discharge wire, a shielding layer, an inner sheath, an armoring layer and an outer protecting layer are sequentially coated outside the cable core and the filling layers. The track traffic cable has high environmental protection property, generates little smoke during burning, does not generate harmful hydracid substances, and has excellent ant and rat preventive property and waterproof property. In addition, the track traffic cable is a novel product integrated with high environmental protection property, ant and rat preventive property, waterproof property and the like, and has wide market prospect.
Description
Technical field:
The utility model relates to a kind of traffic cable, is specifically related to a kind of track traffic cable.
Background technology:
The traffic of Xiao Shouing in the market has the road vehicle low-voltage cable with cable, the automobile branch cable, rail vehicles is with cable etc., they are used in respectively with the automobile is the road vehicle of representative, places such as automobile chassis wiring and rail vehicles connecting line, but development along with society, the bus that needs is many more, the tail gas of bus burning and exhausting is many more, harm to environment is big more, personal automobile is also more and more simultaneously, in order to improve this situation, country begins to develop subway, so subway develops rapidly, development step at the inside, city subway is accelerated, the development need urban light rail of subway, the stube cable of the other equipment of subway signal control device indoor equipment and track, the traffic on the market can not be satisfied the needs of present above-mentioned occasion with cable thus.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of and produces less smog and do not produce harmful hydracid material when both having possessed high environmental-protecting performance, burning, possesses mechanical strength height, good anti-ant mouse performance and the track traffic cable of block-water performance again.
The utility model technical solution problem adopts following technical scheme:
The track traffic cable, the edge cores that thoroughly do away with are twisted into cable core more, be provided with packed layer in the cable core gap, described insulated wire cores from-inner-to-outer is made of conductor and insulating barrier, and cable core and packed layer are coated with waterstop, low smoke and zero halogen glass fibre belt, earial drainage silk, screen, inner sheath, armour and outer jacket outward successively.
Described insulating barrier is made by the IXPE insulating material.
Described waterstop is the glass yarn.
Be axially arranged with an earial drainage silk along cable between described low smoke and zero halogen glass fibre belt and the screen.
Described screen is an aluminium-plastic tape.
Described inner sheath is the anti-ant mouse sheath of low smoke and zero halogen.
Described armour is a zinc-coated wire.
Described outer jacket is the anti-ant mouse sheath of low smoke and zero halogen.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
Conductor adopts the copper core compacted stranded conductor of the 2nd class, can prevent the corrosion of moisture content and other harmful substance; Insulating barrier adopts the IXPE material to make, this material not only has the superior electrical property of polyethylene, and compare with common polythene, its mechanical performance is improved greatly, especially tensile strength is several times of common polythene, the environmental stress resistance performance of this material also improves a lot in addition, common polythene material environmental stress resistance performance is poor, the insulation cracking phenomena in use appears easily, but the environmental stress resistance performance of this new material obtains very big improvement, avoided cable the phenomenon that insulate and ftracture, the useful life of having improved cable greatly in use to occur; Waterstop adopts glass yarn waterstop, and its water absorption capacity surpasses 40ml/g, promptly has block-water performance preferably; Outer jacket adopts the anti-ant mouse sheath material of environmental-friendly halogen-free low-smoke; this material adopts the termite-resistant rodent-resistant repellant that extracts from multiple natural plants; after repeatedly compound, add in the cable sheath material; make cable jacket contain a kind of specific peculiar smell; because of being upset, its sense of smell detests and rejects contact behind the mouse ant class animal contact cable; also can send impalpable information and produce population effect simultaneously, thereby reach the purpose that the protection cable is not destroyed by the mouse ant to colony.Smoke density was very low when the utility model product had burning, non-corrosiveness gas is overflowed, do not produce harmful hydracid material yet, termite-proof and mouse bites, possess advantages such as high flame retardant and block-water performance simultaneously, can be widely used in the place that some personnel relatively concentrate, also be extensive use of in China temperate zone and subtropical zone many mouse ant area.In a word, this utility model product is a kind of new product that environmental protection, anti-ant mouse performance and block-water performance etc. are integrated in one, and vast market prospect is arranged.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Number in the figure: 1 conductor, 2 insulating barriers, 3 packed layers, 4 waterstops, 5 low smoke and zero halogen glass fibre belts, 6 earial drainage silks, 7 screens, 8 inner sheaths, 9 armours, 10 outer jackets.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment:
Embodiment: shown in Figure 1, the described track traffic cable of present embodiment, conductor 1 adopt the copper core of the 2nd class formation to press and are twisted into conductor wire core, and the following step of conductor production process: wire drawing-annealing-twisted wire, stranded conductor wire core has stronger tensile property.Insulating barrier 2 adopts the IXPE Insulation Material, its production process is produced on the SJ65 plastic extruding machine and is finished, adopt tubular molding tool to extrude, to irradiation producer the cable insulation core is carried out irradiation processing then, guarantee that cable has good electrical property, high mechanical performance and stronger tensile strength, its extrusion temperature is according to the difference of warm area and different, body temperature is controlled at 180 ± 10 ℃, head temperature is controlled at 200 ± 5 ℃, die temperature is controlled at 190 ± 5 ℃, can carry out suitable adjustment according to extrusion equipment and material different, differ 5～10 ℃ in winter and summer.Packed layer 3 and waterstop 4 guarantee the roundness of cable.Waterstop 4 adopts glass yarn waterstop, and its water absorption capacity surpasses 40ml/g, promptly has block-water performance preferably.Screen 7 adopts plastic-aluminum combined carrying material, adopts overlapping wrapped mode, and its rate of putting up is not less than 15%.Inner sheath 8 adopts the anti-ant mouse material of low smoke and zero halogens, carries out the zinc-coated wire armouring behind the inner sheath again, and the steel wire radical determines according to actual conditions, and can be suitable adjust, but steel wire is tight after guaranteeing armouring, total backlash is no more than a gauge of wire.Outer jacket 10 adopts the anti-ant mouse outer jacket of low smoke and zero halogen, also adopt tubular molding tool to extrude, extrusion temperature is according to the difference of warm area and different, body temperature is controlled at 115 ± 10 ℃, head temperature is controlled at 140 ± 10 ℃, die temperature is controlled at 130 ± 5 ℃, can carry out suitable adjustment according to extrusion equipment and material different, differs 5～10 ℃ in winter and summer.Production equipment can adopt different sheath extruders to produce according to the size of the outside diameter of cable: the use SJ90 extruder of external diameter below 35mm, the use SJ120 extruder of external diameter more than 35mm.
