Description
Technical field
The utility model is related to power cable technical fields, and in particular to a kind of rail traffic Water-proof mouse Moisture-proof environment-friendlyshoe
Cable.
Background technology
With the development of society, city and urban population concentration effect are obviously accelerated, the track as urban lifeline is handed over
Logical to be rapidly developed, China has become the fastest country of Urban Rail Transit Development in the world.
Main artery in railway traffic engineering is the urban transportation, power supply mode is more, cable run is complicated,
Cable laying space is limited so that partial cables, which will change to ground, to be laid, especially tramcar cable, is largely laid in ground
In face or soil, and the potential hazard factor that ground environment faces is also more and more, and especially rainwater impregnates, and southern area is normal
The generation of rainy water disaster causes cable to impregnate in water for a long time, and the medium and high voltage cable generally use that transmission system uses
Be it is crosslinked polyetylene insulated, crosslinked polyethylene is when cable is run, if moisture immerses in crosslinked polyetylene insulated layer, can exist
Water tree is generated under the action of moisture.The generation of water tree will be such that cable dielectric consume increases, under insulation resistance and breakdown voltage
Drop, the service life of cable are obviously shortened.And cable laying also suffers from biting for worm mouse and stings, influencing cable makes in ground or soil
Safety.
Invention content
In view of this, a kind of rail traffic provided by the utility model Water-proof mouse Moisture-proof environment-friendlyshoe cable, the cable energy
It is enough effectively worm mouse to be prevented to bite cable broken, improve the safety of cable.
For achieving the above object, technical solution used by the utility model is：A kind of rail traffic is anti-with waterproof
Mouse Moisture-proof environment-friendlyshoe cable, including core, the core are provided centrally with strengthening core, and the strengthening core peripheral annular is evenly equipped at least
Three conducting wires are equipped with filler, waterproof layer, erosion resistant coating, shoe are equipped with successively outside the core between the strengthening core and conducting wire
Chamber and outer jacket, the shoe chamber are equipped at least two chambers along radial line direction, worm mouse repellant are filled in the chamber.
Preferably, the conducting wire includes the conductor, insulating layer and shielded layer extruded successively from inside to outside.
Preferably, the conductor is twisted using copper wire, and the insulating layer is that the band-like product of synthetic mica twines by material
Around into the shielded layer uses aluminum foil material.
Preferably, the shoe chamber is uniformly arranged at least four along erosion resistant coating outer surface.
Preferably, the strengthening core is that plastics reinforce tensioning member, and the filler uses cotton material, the erosion resistant coating to adopt
It is formed with styrene materials, the outer jacket uses low-smoke halogen-free polyolefin material.
Preferably, the waterproof layer includes the base of woven dacron and the particulate expandable that is bonded in base, and the expansion is micro-
The material of grain is cellulose, acrylamide, acrylic acid aggregation.
The utility model has the advantages that：In the technical solution of the utility model, the utility model cable is logical
It crosses shoe chamber and is radially equipped at least two chambers, even if the indoor worm mouse repellant of one of chamber stings exposure because of biting for worm mouse
After volatilizing in air, the shoe chamber, which also has in other chambers, is also sealed with worm mouse repellant, moreover it is possible to again to worm mouse into
Row repellent action can extend the time of cable expelling parasite mouse so that cable usage time is longer.Waterproof layer can enhance electricity simultaneously
The waterproof and dampproof performance of cable, the erosion resistant coating can enhance cable corrosion resistance.
Description of the drawings
Fig. 1 is the overall structure block diagram of the utility model.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, it is clear that described embodiment is only the utility model a part of the embodiment, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art institute without creative efforts
The every other embodiment obtained, shall fall within the protection scope of the present invention.
In conjunction with shown in Fig. 1, a kind of rail traffic Water-proof mouse Moisture-proof environment-friendlyshoe cable provided by the utility model includes line
Core, the core are provided centrally with strengthening core 2, and 2 peripheral annular of the strengthening core is evenly equipped at least three conducting wires, the strengthening core
Filler 3 is equipped between 2 and conducting wire, the conducting wire includes the conductor 1, insulating layer 11 and shielded layer extruded successively from inside to outside
12, the core is equipped with waterproof layer 4, erosion resistant coating 5, shoe chamber 6 and outer jacket 7 successively outside.
At least four shoe chamber 6 is evenly distributed on 5 surface of erosion resistant coating, and the shoe chamber 6 is equipped with extremely along radial line direction
Lack two chambers, worm mouse repellant is placed in the chamber.Behind worm damaged by rats bad outer jacket 7, worm mouse can be by shoe chamber 6
It stops, when the bad shoe chamber 6 of worm damaged by rats, worm mouse can bite the shoe chamber 6 close to the indoor worm mouse repellant of outermost layer chamber, worm
Mouse can be driven by the indoor worm mouse repellant of chamber, over time, when shoe chamber 6 drives close to the indoor worm mouse of outermost layer chamber
After keeping away agent volatilization, expelling parasite mouse ability can be more and more weaker, and worm mouse can bite stinging to cable again, but the shoe chamber 6 is along diameter
To equipped at least two chambers, worm mouse can be located next to the indoor worm mouse repellant of next layer of chamber of outermost layer chamber by shoe chamber 6
It drives, the shoe chamber 6 is radially equipped at least two chambers, can extend the time of cable expelling parasite mouse so that cable uses
