Description
Technical field
The utility model relates to a kind of electric wires, and in particular to a kind of corrosion-resistant moisture-proof rat-and-ant proof track of nylon sheath wire cracking resistance
Transport cable.
Background technique
In recent years, the rail traffic in the city in China presents fast-developing situation, and speed is beyond any country, the world
Peak period.As the important component of city bus, urban track traffic meets the basic trip of the people, with people group
Many production and living are closely bound up.In big city especially megalopolis, urban track traffic has been increasingly becoming people's trip
" main channel ".With ramping up for urbanization process, urban rail transit in China construction is expected to welcome the golden period of development.
Mainly there is following disadvantage according to the feedback of each development project:
1) track traffic cable is divided into above and below ground two parts now: 1. since the outer jacket of track traffic cable is all
The be laid in cable of local part of low-smoke halogen-free polyolefin material prolonged exposed protects outside cable after a period of time in the sun
Set will crack；2. the cable that under ground portion uses is handed over due to the influence of construction depth and precipitation, flood, plum rain season, track
Energy cable is often moist.
2) cable of rail traffic has required rat-and-ant proof performance, and used is shield of the chemical method rat-and-ant proof in cable
Chemical agent, but its disadvantage are added in cover material: (1) migration of chemicals contained by sheath will cause environmental pollution；( 2)
Due to the fuel factor of cable, it is sustained rat-and-ant proof drug aging contained by sheath, makes cable rat-and-ant proof reduced performance, therefore cannot protect
The rat-and-ant proof performance for demonstrate,proving cable is permanently effective；(3) in cable rat-and-ant proof layer process, pernicious gas is given out to life
Production person causes health hazard.
3) there are also the complicated often easy sheaths cable of the cable laying environment in tunnel to abrade, wounding causes to influence electricity
The normal use of cable.
Utility model content
Utility model aims to solve the following disadvantages of the above-mentioned prior art: 1. due to track traffic cable
Outer jacket be all low-smoke halogen-free polyolefin material be laid in local part cable it is prolonged exposed when crossing one section in the sun
Between cable jacket will crack；2. the cable that under ground portion uses due to construction depth and precipitation, flood, plum rain season shadow
It rings, track hands over energy cable often moist；3. the cable of rail traffic has required rat-and-ant proof performance, and used is chemistry
Method rat-and-ant proof adds chemical agent in the sheath material of cable, but the migration of chemicals contained by sheath will cause environmental pollution；
4. it is sustained rat-and-ant proof drug aging contained by sheath, makes cable rat-and-ant proof reduced performance due to the fuel factor of cable, therefore not
It can guarantee that the rat-and-ant proof performance of cable is permanently effective；5. giving out pernicious gas to life in cable rat-and-ant proof layer process
Production person causes health hazard；6. the complicated often easy sheath cable of cable laying environment in tunnel abrades, wounding causes
The normal use for influencing cable, provides a kind of corrosion-resistant moisture-proof rat-and-ant proof track traffic cable of nylon sheath wire cracking resistance.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of nylon sheath wire cracking resistance is corrosion-resistant anti-
The outside packet of damp rat-and-ant proof track traffic cable, including conductor, insulating layer, belting layer, water blocking layer and inner sheath, the conductor is set
There is insulating layer, the outside packet of the insulating layer is equipped with belting layer, and the outside packet of the belting layer is equipped with water blocking layer, the water blocking layer
Outside packet be equipped with inner sheath, the inner sheath outside packet be equipped with nylon 11 sheath, the inner sheath be low smoke and zero halogen polyene
Hydrocarbon rat-and-ant proof sheath, the thickness range of the nylon 11 sheath are 1.0mm-1.2mm.Due to nylon material itself have it is good
Heat-resisting quantity, (ageing properties test proves nylon sheath cable ratio for good thermal stability, heat resistanceheat resistant shrinkage, anti-aging property
Common cable service life at least doubles i.e. 40 years or more) the excellent physical performance of resistance to nytron of nylon, chemical stabilization
Property it is good, that is, have excellent oil resistant, it is resistance to liquefaction gas corrosion performance and be able to maintain good mechanical performance and electrical insulation capability, have
Safety and applicability in laying can be improved, so that in complexity in impact resistance and good wearability and self-lubricity
Environment in lay and be also not easy to abrade, wound.The ant-proof mouse-proof ant layer of nylon 11, through GB/T2951.38, " wire and cable is prevented white
Ant test method " it is tested by group's method, nylon sheath surface has no the indentation of apparent termite moth erosion, reaches 1 grade of moth erosion grade.
Nylon material also has and also has good flame retardant property and low smoke and zero halogen performance.
Preferably, the thickness of the low-smoke halogen-free polyolefin rat-and-ant proof sheath is more than or equal to the thickness of the nylon 11 sheath
Degree.
Preferably, the thickness of the insulating layer is greater than the thickness of water blocking layer, the thickness of the water blocking layer is greater than described exhausted
The thickness of edge layer.
Preferably, the thickness value of the nylon 11 sheath is at least the 1/6 of conductor diameter value.
The substantial effect of the utility model is: the utility model passes through the advantages of nylon material, effective solution original
Track traffic cable is to cracking resistance, moisture-proof, anticorrosion, rat-and-ant proof and scratch is avoided to facilitate the problems such as installation, more fully
Ensure the operation of track traffic cable normal table.
