Yarn, inner side halogen-free high flame-retardant band lapping layer, aluminium-plastic tape embossing screen layer, woven shield and inner sheath；The insulation is single
The insulating barrier that line is coated by copper conductor and its outside is constituted.
Further, the copper conductor is stranded soft copper conductor.
Further, the insulating barrier insulate for high density polyethylene (HDPE).
Further, it is provided with least between the inner side halogen-free high flame-retardant band lapping layer and aluminium-plastic tape embossing screen layer
A piece aerial drainage wire.
Further, the woven shield is proof copper-wire braided screen layer.
Further, the inner sheath, inner liner and oversheath are LSOH anti-flaming sheath.
Relative to prior art, the invention has the advantage that：
1) the invention reasonable in design, using flexible conductor lay configuration, solves intercity track in the prior art
Transport cable is because conductor is hard during laying installation, and conductor is in the fracture and constructional difficulties occurred after bending repeatedly
The problems such as.
2) using the vertical bag of aluminium-plastic tape embossing and copper wire woven shielding as screen layer, shielding properties is strong, screen layer is hard
Gu, it is unlikely to deform, the features such as cable has higher tensile strength, anti-long-term vibration and good bending property.
3) band is wrapped using halogen-free high flame-retardant band inside and outside cable core, and inner sheath, inner liner and oversheath use nothing
Halogen low-smoke and flame retardant sheath, makes cable have Halogen, low cigarette, fire resistance, extends the service life of cable.

Describe the invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of inter-city rail transit cable, as shown in figure 1, coated successively from the inside to the outside including cable core and cable core outside
Outside halogen-free high flame-retardant band lapping layer 11, inner liner 12, composite steel-plastic belt corrugated longitudinal wrapping armor layer 13 and oversheath 14；The cable
Core includes at least one quad 1, and the quad includes insulated single wire 2 and its outside of four mutually stranded settings of different colours
Bundle yarn 5, inner side halogen-free high flame-retardant band lapping layer 6, aluminium-plastic tape embossing screen layer 8, the braiding screen coated successively from the inside to the outside
Cover layer 9 and inner sheath 10；In order to further improve the intensity and tensile property of this cable, center can be set to strengthen in cable core
Part, specifically, can be with the stranded setting of each quad, generally, the preferred metalloid core reinforcer of center reinforcemen, the insulation
The insulating barrier 4 that single line is coated by copper conductor 3 and its outside is constituted.
Above-mentioned copper conductor 3 is stranded soft copper conductor.Using flexible conductor lay configuration, intercity track in the prior art is solved
Transport cable is because conductor is hard during laying installation, and conductor is in the fracture and constructional difficulties occurred after bending repeatedly
The problems such as.
Above-mentioned insulating barrier 4 insulate for high density polyethylene (HDPE), with good insulating properties.Above-mentioned inner side halogen-free high flame-retardant band
At least one aerial drainage wire 7 is provided between lapping layer and aluminium-plastic tape embossing screen layer, effectively increases what cable was used
Security.
Above-mentioned woven shield 9 is proof copper-wire braided screen layer.It is pointed out that using the vertical bag of aluminium-plastic tape embossing and
Copper wire woven is shielded as screen layer, and shielding properties is strong, screen layer is firm, is unlikely to deform, and cable has higher tensile strength, resisted
The features such as long-term vibration and good bending property.
Above-mentioned inner sheath, inner liner and oversheath are LSOH anti-flaming sheath.Cable core band uses halogen-free high flame-retardant
With wrapped, inner sheath, inner liner and oversheath use LSOH anti-flaming sheath, cable is had Halogen, low cigarette, anti-flammability
Can, extend the service life of cable.
This inter-city rail transit cable manufacturing process is：The insulated single wire of four different colours is first twisted into quad 1,
And aerial drainage wire 7 is then arranged on inner side Halogen high around wrapping yarn 5 and cladding inner side halogen-free high flame-retardant band lapping layer 6 outside
On inhibiting tape lapping layer 6, aluminum plastic composite belt longitudinal is bundled into by pipe using the vertical chartered plane of embossing and is coated on Halogen height on the inside of described be coated with
On the insulated single wire 2 of four mutually stranded settings of different colours of inhibiting tape lapping layer 6, outside aluminium-plastic tape embossing screen layer 8
Woven shield 9 is coated again, then one layer of inner sheath 10 is extruded outside woven shield 9 using sheathing machine, then will be all
Line group is made by twisting cable core together.
Afterwards, halogen-free high flame-retardant band lapping layer 11, inner liner 12 on the outside of being coated successively outside cable core, then using the vertical bag of embossing
Machine is in the outer cladding composite steel-plastic belt corrugated longitudinal wrapping armor layer 13 of inner liner 12, then extrudes one layer of oversheath 14.This practicality is made
New resistance to compression impact resistance internal screening railway digital signal cable.Cable anti false film can be set on the outside of oversheath, it is necessary to say
Bright, described quad 1 can also be to line group.
The preferred embodiment of the invention is the foregoing is only, creation is not intended to limit the invention, it is all at this
Within the spirit and principle of innovation and creation, any modification, equivalent substitution and improvements made etc. should be included in the invention
Protection domain within.
