Description
Technical field
The present invention relates to cable, specifically a kind of environmental protection oilproof flame retardant rail transit locomotive cable.
Background technique
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, the especially some control cables of existing locomotive cable or signal cable, the small cable tensile property in section is poor,
Conductor copper wire is easy to be broken during stretching, is unable to satisfy locomotive high-speed cruising requirement.Being badly in need of exploitation has Halogen, low
The environment-friendly cable of the performances such as cigarette, wear-resisting, environmentally friendly oilproof flame retardant, is used for Rapid transit railway locomotive cable.
Summary of the invention
In order to make up prior art problem, the object of the present invention is to provide a kind of high-intensitive, wear-resisting railway locomotive cable electricity
Cable, it is structurally reasonable, there are the performances such as Halogen, low cigarette, high intensity, anti-vibration.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is that：
A kind of environmental protection oilproof flame retardant rail transit locomotive cable, including several equally distributed conductors, which is characterized in that
Several conductors are all made of the 6th class tinned copper wire and the twisted composition of aramid fiber yarn synnema, and synnema pitch ratio is not more than 12 times, several conductors
The outer insulating layer that is enclosed with respectively constitutes insulated wire cores, and the mutually twisted bunchy of insulated wire cores constitutes cable core, is successively enclosed with outside cable core
Wrapping layer, separation layer, composite shielding layer, composite shielding layer are wrapped with armor, and the outer extrusion moulding of armor has nylon sheath wire
Layer, gap filling has fire-retardant fireproof quartz fibre filler between several conductors inside the cable core.
Further, tinned copper wire and aramid fiber yarn braid shielded structure are added after the composite shielding layer is shielded using aluminium strip longitudinal wrap
At.
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 overlap 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 use 125 DEG C of heatproof, low-smoke non-halogen flame-retardant crosslinked polyolefin materials, lead to
Crossing electron irradiation crosslinking process makes its crosslinking, so that cable has good low cigarette, Halogen, flame retardant property, and there is 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 by the external world compared with strong pulling force, 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 constituted using the 6th class tinned copper wire and aramid fiber yarn synnema are twisted, is enhanced cable core intensity, is less prone to disconnected core, simultaneously
With softness well.
Detailed description of the invention
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 embodiment
Technical solution 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
Personnel's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
As shown in Figure 1, the present invention provides a kind of environmentally friendly oilproof flame retardant rail transit locomotive cable, including several uniform points
The conductor 1 of cloth, which is characterized in that several conductors 1 are all made of the 6th class tinned copper wire 1-1 and the twisted composition of aramid fiber yarn 1-2 synnema,
Synnema pitch ratio is not more than 12 times, is enclosed with insulating layer 2 respectively outside several conductors 1 and constitutes insulated wire cores, insulated wire cores mutually twist
It synthesizes beam and constitutes cable core, wrapping layer 3, separation layer 4, composite shielding layer 5 are successively enclosed with outside cable core, is wrapped up outside composite shielding layer 5
There is armor 6, the outer extrusion moulding of armor 6 has nylon sheath wire layer 7, there is gap filling between several conductors inside the cable core
Fire-retardant fireproof quartz fibre filler 8.
The composite shielding layer 5 adds tinned copper wire and aramid fiber yarn braid shielded to constitute after shielding using aluminium strip longitudinal wrap.
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 overlap rate is not less than 25%.
