Product tend not to the various rigors for meeting laying simultaneously；The use environment of urban light rail subway cable is mostly densely populated
Underground, once fire occurs, the environment of underground sealed brings very big difficulty to personnel escape and fire-fighting work.Therefore to fire-retardant
Performance requirement is higher, and fire resistance will meet the requirement of A levels in GB/T18380.3.Meanwhile smog and toxic gas during burning
Release can hinder the progress of fire-fighting work, and sour gas can all damage to people and equipment, therefore smog during to burning
Also there is higher requirement with the burst size of toxic gas；Urban light rail subway cable due to the effect of environment and meteorologic factor,
Cable is possible to long period laying in a humidity environment, and hydrone is possible to immerse cable, invades inside cable, exhausted
Edge absorption absorbs, and causes the decline of electric property, can cause oxidation, the corrosion of conductor, not only influences the electrical property of cable, and
Abnormal broken line accident can occur when serious, cable there will be water-proof function；Urban light rail subway is laid in underground for a long time with cable, is held
It is vulnerable to toy（Such as muroid, ant class）Attack, influence the performance of cable, cable should have termite-resistant rodent-resistant function；City is light
If rail subway with cable cable is used in subway, but is laid in elevated railway, may thus be subjected to for a long time
Easily there is color fading, mechanical thing for a long time by solar radiation in the test of solar radiation and various meteorological conditions, the sheath of cable
Phenomena such as reason hydraulic performance decline even ftractures, cable should have anti-ultraviolet function；Urban light rail subway cable laying space has
Limit, on the one hand requires direct current cables lightweight, flexible, radius of turn is small.On the other hand, the cable kind laid in roughing-in
Class is more, quantity is more, it is necessary to which the outside diameter of cable is small, easy laying；Urban light rail subway is in addition to substantial amounts of power cable is needed, it is also necessary to makes
With substantial amounts of control, signal, protection and measurement cable, prior art is due to consideration that the factor of electric interfering field, and often electric power is electric
Cable is individually processed with control, signal, protection and measurement cable, laid respectively, and this not only brings difficulty to construction, and also increasing makes
With and construction cost；And because the wire core diameter of control, signal, protection and measurement cable is smaller, tensile strength is relatively low, is applying
Easily abrade or break during if.
The content of the invention
Technical problem to be solved：
The purpose of this utility model, which is to provide, a kind of has higher insulating properties, fire-retardant A levels, low smoke and zero halogen, fire resisting, anti-
Water, termite-resistant rodent-resistant, antiultraviolet, anti-electric jamming, flexibility are good, good bending property, a kind of compact-sized city
City's power cable for rail transit.
Technical scheme：
A kind of urban track traffic power cable, including copper conductor, insulating barrier, waterproof layer, it is characterised in that the electricity
Power cable includes copper conductor, insulating barrier, metallic shield, comprehensive waterproof layer, armor and flame-retardant layer successively from inside to outside；It is described exhausted
Edge layer includes inner shield, XLPE insulation and external shield from inside to outside；The inner shield is semiconductive conductor shield, and external shield is
Semi-conductive insulation shield layer, XLPE insulation is crosslinked polyetylene insulated layer；The inner shield, XLPE insulation and external shield use
Dry type is crosslinked extrusion forming；The metallic shield is copper strip shielding；The comprehensive waterproof layer includes blocking water from inside to outside successively
Band, aluminium-plastic tape, MDPE inner liners；The armor is hard brass band；The flame-retardant layer includes low successively from inside to outside
Protected outside cigarette halogen-free high flame-retardant band and resistant environmental low-smoke halogen-free flame polyolefin.
Further, it is shield in high fire-retardance oxygen barrier layer between the comprehensive waterproof layer and armor.
Further, the copper conductor is that at least two soft round copper wires of diameter identical are well-regulated, by concentric type, and
What successive layers formed according to different direction process.
Beneficial effect：
（1）The insulating barrier of patent of the present invention is three-layer co-extruded formation, internal layer is semiconductive conductor shielding by up of three layers
Layer, outer layer is semi-conductive insulation shield layer, middle then be crosslinked polyetylene insulated layer, and three layers are squeezed into by high-quality material
Type, by being crosslinked specially treated, the linear molecular structure of polyethylene is changed into solid netted molecular structure, substantially increases production
Electric property, physical property, mechanical performance and other properties of product.It is three-layer co-extruded to be chemically crosslinked using dry type, effectively
Prevent the generation of insulated water tree.And the utility model ensures excellent fire prevention and fire-retardant using wrapped low-smoke bittern-free highly fire-proof band
Performance.
（2）The sectional area of copper conductor of the present utility model is 50~630mm2, and geometry is round, is by some
The soft round copper wire of diameter identical is well-regulated, concentric type, and successive layers time form according to different direction process.Insulated wire
Core is single, and geometry is fixed, and stability is high, on cable can curvature influence very little.
（3）The utility model uses comprehensive waterproof structure, and longitudinal water-blocking uses overlapping wrapped one layer of 0.2mm waterstop,
After the band water-swellable, copper strip shielding layer can be blocked up watertight；Radial direction waterproof is using vertical one layer of aluminium-plastic tape of bag and squeezes
The composite sheath of one layer of MDPE inner liner is wrapped, effectively prevents the intrusion of moisture, moisture.
（4）The utility model uses one layer of hard brass band armouring, can prevent toy from biting cable and to exempt from cable
In some mechanical damages.
