Description
Technical field
The present invention relates to field of cable technology, more particularly to a kind of aerial cable.
Background technology
Cable refers to the material for electric power, communication and associated transport purposes, at present, with the development of society, cable
Demand rises steadily, and requirement of the people to cable also more and more higher, especially in the environment of aerial cable, cable is by outer
During portion's stress, its internal wire is easily subjected to displacement, and causes cable local temperature too high, influences the communication effect of cable
Fruit；Connected between the cable of cable typically by a dowel, when dowel is damaged, cable can divide each other
From easily causing to damage to the sheath of cable, influence the performances such as the wear-resisting of cable, high temperature resistant；Existing cable radiating effect compared with
Difference, during cable work, it is impossible to heat caused by conductor is effectively dissipated, causes conductor temperature too high, causes it
Current-carrying capacity reduces.Above mentioned problem urgent need to resolve.
The content of the invention
To solve technical problem present in background technology, the present invention proposes a kind of compact-sized, firm, thermal diffusivity of connection
The good aerial cable of energy.
A kind of aerial cable proposed by the present invention, including more parallel longitudinal cables, pass through more between adjacent cables
Dowel connects, more dowel diameter parallels；
Every cable includes restrictive coating, armor, the cable core being made up of three wires and annular brace core, each wire bag
The conductor positioned at middle part, the insulating barrier being coated on outside conductor are included, annular brace core is made of flexible heat-conducting polymer material
And its periphery is closed, annular brace core inner is embedded with the flexible radiating tube of multiple annular distributions, annular brace in-core week with
Wire periphery abuts；Armor is coated on outside the cable core, and restrictive coating is coated on outside armor.
Preferably, rounding off between the cable and dowel.
Preferably, it is provided with cooling agent in flexible radiating tube.
Preferably, dowel axis and cable diameter parallel.
Preferably, it is provided with tensile steel wire in dowel.
Preferably, armor is stainless steel band lock armo layer.
Aerial cable proposed by the present invention, including more parallel longitudinal cables, pass through more connections between adjacent cables
Muscle connects, more dowel diameter parallels；Every cable includes restrictive coating, armor, by three wires and annular brace core structure
Into cable core, each wire includes the conductor positioned at middle part, the insulating barrier that is coated on outside conductor, and annular brace core is using flexible
Heat-conducting polymer material is made and its periphery is closed, and annular brace core inner is embedded with the heat dissipation metal pipe of multiple annular distributions,
Annular brace in-core week abuts with wire periphery；Armor is coated on outside the cable core, and restrictive coating is coated on armor
It is outside.Pass through the design of the above-mentioned construction of cable, on the one hand, a cable includes more cables, passes through more between adjacent cables
Dowel connects, and in any one or more dowel damage, remaining dowel remains to be fixedly connected with adjacent both threads cable,
When the cable is collided by external force, use more safety is firm；On the other hand, resilient support core effectively fixes wire, prevents
The displacement of wire, the wire stress inside cable are indeformable so that cable interior temperature distribution is uniform, stable current-carrying capacity of cable；
Another further aspect, resilient support core by flexible heat-conducting polymer material into, improve cable intensity and toughness simultaneously, can also inhale
Heat caused by wire is received, and is passed to its internal radiating tube, to reduce the temperature during cable use, ensures electricity
Cable will not answer temperature too high and cause the reduction of its current-carrying capacity.
Brief description of the drawings
Fig. 1 is a kind of structural representation of aerial cable proposed by the present invention.
Embodiment
As shown in figure 1, Fig. 1 is a kind of structural representation of aerial cable proposed by the present invention.
Reference picture 1, the present invention propose a kind of aerial cable, including more parallel longitudinal cables, led between adjacent cables
Excessive root dowel 6 connects, the more axis of dowel 6 and cable diameter parallel；
Every cable includes restrictive coating 5, armor 4, the cable core being made up of three wires 1 and annular brace core 2, and every is led
Line 1 includes the conductor 11 positioned at middle part, the insulating barrier 12 being coated on outside conductor 11, and annular brace core 2 is high using flexible heat conduction
Molecular material is made and its periphery is closed, and the flexible radiating tube 3 of multiple annular distributions, ring are embedded with inside annular brace core 2
The inner circumferential of shape supporting-core 2 abuts with the periphery of wire 1；Armor 4 is coated on outside the cable core, and restrictive coating 5 is coated on armouring
Outside layer 4.
In such scheme, rounding off between the cable and dowel 6, the connection between cable and dowel 6 is more
It is firm；Cooling agent is provided with flexible radiating tube, it is more preferable to the radiating effect of cable.
During specific design, tensile steel wire 7 is provided with dowel 6, enhances the mechanical performance of dowel 6, effectively
The fracture of dowel is prevented, stabilizes the communication of cable.
Armor 5 uses the chain armoured process of stainless steel band, plays longitudinal stress effect, improves anti-in cable use
Rust, tension, bending property；And the chain armor 5 of stainless steel band plays a part of cable shield, Exterior cable electricity can be resisted
The signal interference of magnetic wave.
Aerial cable proposed by the present invention, passing through the design of the construction of cable, on the one hand, a cable includes more cables,
Connected between adjacent cables by more dowels, in any one or more dowel damage, remaining dowel remains to
Adjacent both threads cable is fixedly connected with, makes cable more safe firm when being collided by external force；On the other hand, it is effective to flexibly support core
Wire is fixed, prevents the displacement of wire, it is indeformable by the wire stress inside cable, make the cable interior temperature distribution equal
It is even, the current-carrying capacity of stable cable；Another further aspect, resilient support core is by flexible heat-conducting polymer material into improving the strong of cable
Degree and toughness simultaneously, go back heat caused by absorbable guide line, and are passed to its internal radiating tube, are made with reducing cable
Temperature during, ensure that cable will not answer temperature too high and cause the reduction of its current-carrying capacity.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
