Description
Technical field
The present invention relates to cable, specifically a kind of high intensity, wear-resisting type rail transit locomotive cable.
Background technology
With the fast development of state-owned railroads system, " recovery number " motor-car independent research, in terms of communications and transportation, future becomes
Gesture is that rapidly and efficiently, existing locomotive cable especially some control cables or signal cable, the small cable tensile property in section is poor,
Conductor copper wire is easy to be broken in drawing process, cannot be satisfied locomotive high-speed cruising requirement.It is badly in need of exploitation with Halogen, low
The environment-friendly cable of the performances such as cigarette, wear-resisting, high temperature resistant, high intensity is used for Rapid transit railway locomotive cable.
Invention content
In order to make up prior art problem, the object of the present invention is to provide a kind of high intensity, wear-resisting railway locomotive cable electricity
Cable, it is reasonable for structure, there are the performances such as Halogen, low cigarette, high intensity, wear-resisting.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
A kind of high intensity, wear-resisting type rail transit locomotive cable, including several conductors, several conductors are all made of
6 class tinned copper wires are not more than 12 times, insulation are enclosed with respectively outside several conductors with the twisted composition of aramid fiber yarn synnema, synnema pitch ratio
Layer constitutes insulated wire cores, and the mutually twisted bunchy of insulated wire cores constitutes cable core, is enclosed with fireprotection layer, separation layer, multiple outside cable core successively
Shielded layer is closed, composite shielding layer adds tinned copper wire and aramid fiber yarn braid shielded to constitute after being shielded using aluminium strip longitudinal wrap, composite shielding
Layer is wrapped with armor, and the outer extrusion moulding of armor has nylon sheath wire layer.
Further, the fireprotection layer is all made of ceramic fire resisting composite band and is made, and wrapped cap rate is not less than 50%.
Further, the insulating layer uses material for low-smoke non-halogen flame-retardant cross-linking radiation polyolefin.
Further, the separation layer is overlapped wrapped composition using high temperature resistance polyester band, and wrapped cap rate is not less than 25%.
The beneficial effects of the invention are as follows：
The configuration of the present invention is simple, cable insulation are led to using 125 DEG C of heatproof, low-smoke non-halogen flame-retardant crosslinked polyolefin materials
Crossing electron irradiation crosslinking process makes its crosslinking so that cable has good low cigarette, Halogen, flame retardant property, and with heatproof etc.
Grade high (125 DEG C), resistance to environmental aging performance are excellent, meet requirement；Cable shield uses double-layer shielding structure, can not only
The effective generation for inhibiting " cross-talk " phenomenon, meanwhile, it is woven using tinned copper wire and aramid fiber yarn, it can be at some extent as holding
It is influenced compared with strong pulling force by the external world, plays core wire protective effect, especially section small electric cable in connecting portion, tensile strength effect
It is more prominent；The coat layer of power cable is made of nylon sheath wire, and stronger wear-resisting property can effectively avoid causing cable because of friction
Damage；Conductor is enhanced cable core intensity, is less prone to disconnected core, simultaneously using the 6th class tinned copper wire and the twisted composition of aramid fiber yarn synnema
With softness well.
Description of the drawings
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is schematic structural view of the invention.
Specific implementation mode
Technical scheme of the present invention is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation
Example is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill
The every other embodiment that personnel are obtained without making creative work, shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of high intensity of present invention offer, wear-resisting type rail transit locomotive cable, including several conductors, institute
The several conductors 1 stated are all made of the 6th class tinned copper wire 1-1 and the twisted composition of aramid fiber yarn 1-2 synnemas, and synnema pitch ratio is not more than 12
Times, insulating layer 2 is enclosed with outside several conductors 1 respectively and constitutes insulated wire cores, the mutually twisted bunchy of insulated wire cores constitutes cable core, cable core
Outer to be enclosed with fireprotection layer 3, separation layer 4, composite shielding layer 5 successively, composite shielding layer 5 adds plating after shielding 5-1 using aluminium strip longitudinal wrap
Tin copper wire and aramid fiber yarn braid shielded 5-2 are constituted, and can effectively inhibit the generation of " cross-talk " phenomenon, meanwhile, using tinned copper wire
With aramid fiber yarn braid shielded 5-2, aramid fiber yarn as synthetic fibers there is high-strength tensile to drag performance, at some extent as
Protective layer plays a protective role, and composite shielding layer 5 is wrapped with armor 6, and cable strength can be improved, be extruded into outside armor 6
Type has nylon sheath wire layer 7.
The fireprotection layer 3 is all made of ceramic fire resisting composite band and is made, and wrapped cap rate is not less than 50%.
The insulating layer 2 uses material for low-smoke non-halogen flame-retardant cross-linking radiation polyolefin.
The separation layer 4 is overlapped wrapped composition using high temperature resistance polyester band, and wrapped cap rate is not less than 25%.
The embodiments of the present invention described above are not intended to limit the scope of the present invention, any in the present invention
