Abstract
The utility model is applied in the technical field of cables and provides a control cable for a metro. The control cable comprises at least two conducting wires, a wrapping tape and a jacket, wherein the conducting wires are wrapped together by the wrapping tape; the jacket is sleeved outside the wrapping tape; each of the conducting wires comprises an inner conductor, an insulating layer and a first woven layer which are coaxially arranged from inside to outside; a first wrapping isolated layer made of fireproof materials is arranged between the inner conductor and the insulating layer; a second woven layer is also sleeved outside the wrapping tape; and a second wrapping isolated layer made of fireproof materials is arranged between the second woven layer and the jacket. In the utility model, the wrapping isolated layers made of fireproof materials are arranged between the inner conductor and the insulating layer as well as between the wrapping tape for wrapping the conducting wires together and the jacket; therefore, the fireproof property of the cable is greatly improved; and when a fire breaks out, the cable can be guaranteed to work normally.
Description
Technical field
The utility model relates to a kind of cable, more particularly, relates to a kind of subway control cable.
Background technology
At present, subway development of domestic each big city rapidly, its supporting railcar is with control cable widespread production.Because in use occurring stretching repeatedly with control cable easily, railcar cause conductor wire core to break or insulating sleeve is broken, cause a serious accident easily, and railcar is subjected to the pollution cable surface of mineral oil and fuel oil to be prone to the combustion phenomena of catching fire with control cable in long-term the use, and present railcar control cable product, its main performance is confined to low-smoke non-halogen flame-retardant, its fire resistance is bad, when running into fire, easily lighted, bring difficulty for fleeing from of personnel with the operate as normal of other system, and then cause unnecessary loss, therefore railcar need improve with control cable and be perfect, with further raising fail safe.
The utility model content
Technical problem to be solved in the utility model is to overcome the defective of prior art, and subway control cable a kind of simple in structure, safe in utilization is provided.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of subway control cable is provided, comprise at least two leads, with each wrapped in wire in the twining package tape of one and be sheathed on sheath outside the twining package tape, each described lead comprises the inner wire of coaxial setting from inside to outside, the insulating barrier and first braid, be provided with the first wrapped separator that refractory material is made between described inner wire and the described insulating barrier, described twining package tape also is arranged with second braid outward, is provided with the second wrapped separator that refractory material is made between described second braid and the described overcoat.
Further, be filled with polyethylene fibre and the stranded filler of polyolefine material between each lead.
Further, described twining package tape adopts the polyester film coiling to form.
In the utility model, to between the twining package tape of one and sheath, set up the wrapped separator that refractory material is made between the inner wire of cable and the insulating barrier and with each wrapped in wire, thereby improved the fire resistance of cable greatly, guaranteed that cable still can operate as normal when breaking out of fire.
Description of drawings
Fig. 1 is the cross section view of the control cable that is used for subway one preferred embodiment that provides of the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to Fig. 1, the cross section view of the control cable that is used for subway one preferred embodiment that provides for the utility model.Described subway usefulness control cable 100 comprises at least two leads 200, each lead 200 is wrapped in the twining package tape 300 of one and is sheathed on twining package tape 300 sheath 400 outward.In the present embodiment, lead 200 is 7, and is the triplex row arrangement, and first row and the third line are respectively 2,3 of second behaviors.Each lead 200 comprises inner wire 210, insulating barrier 220 and first braid 230 of coaxial setting from inside to outside, be provided with the first wrapped separator 240 that refractory material is made between inner wire 210 and the insulating barrier 220, twining package tape 300 outer also being arranged with are provided with the second wrapped separator 600 that refractory material is made between second braid, 500, the second braids 500 and the overcoat 400.By in the first wrapped separator 240 being set between the inner wire 210 of cable 100 and the insulating barrier 220, being wrapped between the twining package tape 300 of one and the sheath 400 in each lead 200 and setting up the second wrapped separator 600 that refractory material is made, like this, promptly in cable 100, set up two-layer fire resistance good isolation layer, thereby improved the fire resistance of cable 100 greatly, guaranteed that cable 100 still can operate as normal when breaking out of fire.
Particularly, in the present embodiment, the described first wrapped separator 240 and the second wrapped separator 600 all adopt mica tape to make.Mica has high electrical insulating property, antiacid caustic corrosion, anti-elasticity, toughness and sliding, makes separator with it, has improved the security performance of cable 100 greatly.
In the present embodiment, insulating barrier 220 adopts 125 ℃ of cross-linking radiation polyolefin to make, this insulating barrier is base-material with the vistanex, add high-quality and efficient halogen-free flame retardants, crosslinking agent and other processing aid, form through mixing, plasticizing, granulation, it not only has good mechanical and physical performance, electrical property, fire resistance and process industrial art performance, and has characteristics such as not halogen-containing, that the amount of being fuming is low.
Further, be filled with the stranded filler 700 of polyethylene fibre and polyolefine material between each lead 200, strengthened the fire resistance of cable 100 so on the one hand, also improved the tensile property of cable 100 on the other hand, prolonged the useful life of cable 100.
Further, in the present embodiment, twining package tape 300 adopts flexible polyester film overlay coiling to form, and by the parcel of twining package tape 300, has further improved the rounding performance of cable 100, has dwindled the external diameter of cable 100, saves material.
Preferably, in the present embodiment, first braid 230 and second braid 500 all adopt the high-strength polyethylene fiber braiding, have also further improved the tensile property of cable 100, prolong the useful life of cable 100.
Preferably, in the present embodiment, sheath 400 adopts super flexible low-smoke non-halogen flame-retardant cross-linked polyolefin material to make.The sheath 400 that adopts this material to make has higher bending property, and is more convenient during use, and its low smoke and zero halogen performance also makes it use more environmental protection simultaneously.
To sum up, the cable 100 that the utility model provides has low-smoke non-halogen flame-retardant, intensity height, fire-resistant, soft, good bending property, bears performances such as power is good, reversed torsion stretches and to cause lead to break or sheath is broken in the time of can effectively preventing to be used for railcar, also effectively avoid the incendive phenomenon of cable chance naked light in the environment of mineral oil and fuel oil pollution, thereby improved the cable safety in utilization greatly.
Below only be preferred embodiment of the present utility model,, all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model not in order to restriction the utility model.
