Abstract
The utility model provides a fire-retardant comprehensive shielding subway light rail signal cable of low smoke and zero halogen, includes cable core and oversheath, has several wire group in the cable core, wraps cable core band layer, steel band armor shielding layer between cable core and the oversheath in proper order, has half and above wire group in the several wire group to be equipped with the shielding layer outward, is equipped with the cable core shielding layer between cable core band layer and steel band armor shielding layer. The diameter of the conductor of each wire is 0.40mm-1.53mm, and the insulating layer of each wire is of a skin-foam-skin structure or a foam-skin structure; the structure of the shielding layer of the lead group is as follows: double-layer or single-layer copper strip lapping or single-layer copper strip embossing longitudinal wrapping or weaving by adopting copper wires or tinned copper wires; the cable core shielding layer is formed by longitudinally wrapping an aluminum-plastic composite tape or a pure aluminum tape or a pure copper tape. The invention has good shielding function, can reduce the mutual interference between cable conductor groups and the interference of external electromagnetic field to the cable; the mechanical and physical properties and the flame retardant property are enhanced, and the use requirement of the existing subway light rail system on the signal cable can be met.
Description
Technical field
The present invention relates to a kind of signal cable, especially be applied to the signal cable of field of track traffic such as subway light rail.
Background technology
Have the signal cable that is used for field of track traffic such as subway light rail now, its basic structure is: be twisted into the lead group by insulated conductor, the lead group is twisted into cable conductor, wrapped steel-tape armouring screen and oversheath outside cable conductor.The insulation layer structure of insulated conductor is real core insulation layer, and transmission attenuation is bigger; Do not have electromagnetic armouring structure between the lead group in the cable conductor, have certain phase mutual interference; Cable conductor is only established one deck steel-tape armouring screen outward, and the ability of anti-electromagnetic interference is relatively poor.
Summary of the invention
In order to overcome the deficiency that has the signal cable that is used for field of track traffic such as subway light rail now, the invention provides a kind of low-smoke halogen-free flame-retardant comprehensive shielded subway light rail signal cable.The transmission attenuation of this cable is little; Phase mutual interference between the cable core inside conductor group is few; The ability of the anti-electromagnetic interference of cable is stronger.
A kind of low-smoke halogen-free flame-retardant comprehensive shielded subway light rail signal cable provided by the invention, comprise cable core and oversheath, have several lead groups in the cable core, coat cable core belting layer, steel-tape armouring screen between cable core and the oversheath successively, there is half and more lead group to be provided with screen outward in several lead groups, between cable core belting layer and steel-tape armouring screen, is provided with the cable core screen.
The diameter of the conductor of every lead of the present invention is 0.40mm-1.53mm, and the insulating barrier of every lead is skin-bubble-skin structure or bubble-skin structure.
The structure of the screen of lead group of the present invention is: bilayer or individual layer copper strips are wrapped or individual layer copper strips embossing is vertical wraps or adopts copper wire or tinned copper wire braiding to form.
Cable core screen of the present invention adopts the vertical bag of aluminium-plastic tape or fine aluminium band or fine copper band to form.
The invention has the beneficial effects as follows: have good function of shielding, can reduce the interference of phase mutual interference between the cable conductor group and extraneous electromagnetic field cable; Mechanical and physical performance and fire resistance strengthen, and can satisfy the instructions for use of existing subway light rail system to signal cable.
Description of drawings
Fig. 1 is a cross sectional representation of the present invention.
In Fig. 1,1. conductor, 2. insulating barrier, 3. lead, 4. lead group, 5. cable core 6. is provided with the lead group of screen, 7. screen, 8. cable core belting layer, 9. cable core screen, 10. steel-tape armouring screen, 11. oversheaths.
Embodiment
With reference to Fig. 1, the insulating barrier 2 that coats skin-bubble-skin structure or bubble-skin structure outside diameter is conductor 1 between the 0.40mm-1.53mm is made lead 3, with the lead 3 stranded lead groups 4 of making, and half and more lead group is wherein coated screen 7 outward make the lead group 6 that is provided with screen 7.Screen 7 is by bilayer or the individual layer copper strips is wrapped or individual layer copper strips embossing is indulged bag or adopt copper wire or the tinned copper wire braiding forms.Again several lead groups 4 and several lead groups 6 that are provided with screen 7 are twisted into cable core 5, outside cable core 5, coat cable core belting layer 8 backs and adopt aluminium-plastic tape or fine aluminium band or the vertical bag of fine copper band cable core screen 9, adopt the wrapped or vertical Baogang of the individual layer steel band embossing band armouring screen 10 of double-deck steel band then, adopt low-smoke and halogen-free flame retardant polyolefin jacket material to coat oversheath 11 again.
Claims (2)
1. low-smoke halogen-free flame-retardant comprehensive shielded subway light rail signal cable, comprise cable core and oversheath, have several lead groups in the cable core, coat cable core belting layer, steel-tape armouring screen between cable core and the oversheath successively, it is characterized in that having in several lead groups half and more lead group to be provided with screen outward, between cable core belting layer and steel-tape armouring screen, be provided with the cable core screen.
2. by the described low-smoke halogen-free flame-retardant comprehensive shielded subway light rail signal cable of claim 1, the diameter that it is characterized in that the conductor of every lead is 0.40mm-1.53mm, and the insulating barrier of every lead is skin-bubble-skin structure or bubble-skin structure.
