Description
Technical field
Field of cable technology is the utility model is related to, more particularly, to a kind of shock resistance low temperature resistant cable.
Background technology
With expanding economy, it is necessary to become more and more diversified using the place of cable, have to the performance indications of cable
More strict and diversified requirement, such as the index such as insulating properties, tensile strength, temperature in use, fire resistance have strictly
Requirement, constantly improve cable performance be economy and social development active demand.But traditional cable sheath material
The problem of poor shock resistance, low temperature resistant effect difference be present, when running into impact, low temperature environment, the wire inside cable holds more
Easily exposure or fracture, causes the interruption of cable transmission, causes the short circuit of electrical equipment, so as to shorten the service life of cable, and then give
Actual use brings many inconvenience, or even threatens the security of the lives and property of the people.
Therefore, it is necessary to propose the defects of a kind of new construction of cable is to overcome traditional cable.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of low temperature resistant cable of shock resistance.
To achieve these goals, the utility model shock resistance low temperature resistant cable uses following technical scheme：
A kind of cable, including sheath and the cable core that is arranged in the sheath, the sheath include the first protective layer, set
It is described in the polyaryl fibrous layer in first protective layer and the second protective layer being arranged in the polyaryl fibrous layer
Cable core is arranged in second protective layer；The cable core includes four wires, the axle of three wires in four wires
To axis arrangement triangular in shape, a wire is arranged in the hole between three wires；Set in the wire
Flexible lines.
As a kind of perferred technical scheme, first protective layer and/or the second protective layer are haloflex material.
As another preferable technical scheme, first protective layer and/or the second protective layer be haloflex with
Butadiene-styrene rubber mixing material.
As the technical scheme further preferred to above technical scheme, the wire is twisted by stranded copper wire.
As further preferred technical scheme, the cable core also includes rubber filling layer, the rubber filling layer filling
The space of the wire and second protective layer.
As further preferred technical scheme, the circular in cross-section of the cable core.
Shock resistance low temperature resistant cable of the present utility model, sheath include three-decker, and wherein intermediate layer is polyaryl fiber
Layer, have tensile strength height, wettability, dimensionally stable, heat-resisting good, wear-resisting, cut resistant, acidproof, impact resistance, flame resistance excellent etc.
Advantage, ensure the reliability of cable cover(ing).Meanwhile wire includes four, wherein three axial axis settings triangular in shape, in addition
A piece wire is arranged in the space between three wires, and the cable of the structure has good impact resistance and lower temperature resistance,
In order to ensure that cable still has good pliability at low temperature, avoid causing cable brittle failure during low-temperature bending, in wire also
It is provided with flexible lines.Therefore, the utility model cable has the advantages of reliability is high, and shock resistance resistance to low temperature is good.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model shock resistance low temperature resistant cable embodiment.
Embodiment
Below in conjunction with the accompanying drawings, the concrete structure of the utility model shock resistance low temperature resistant cable is described in detail.
As shown in figure 1, the utility model cable includes sheath and cable core, sheath includes the first protective layer 11, is arranged at
Polyaryl fibrous layer 12 in one protective layer 11 and the second protective layer 13 being arranged in polyaryl fibrous layer 12, cable core are set
In in the second protective layer 13, cable core includes four wires 2, the axial axis row triangular in shape of three wires 2 in four wires 2
Cloth, a remaining wire 2 are arranged in the space of three wires 2., can be effective because sheath sets polyaryl fibrous layer
Improve cable stretch-resistance and reliability, three arrangements triangular in shape in four wires 2, the 4th wire 2 be arranged on this three
Angular inside, the impact resistance and lower temperature resistance of cable can be effectively improved, in order to ensure that cable still has at low temperature
Good pliability, bending cable brittle failure is avoided, flexible lines are additionally provided with wire 2.Therefore, the utility model cable has
Reliability is high, the advantages of shock resistance and good resistance to low temperature.
Preferably, in order to further improve the weatherability of the utility model cable and ageing resistace, first protects
The protective layer 13 of sheath 11 and/or second can be haloflex material or haloflex and butadiene-styrene rubber mixing material.
In the present embodiment, in order to increase the surface area of electric wire, the loss of electric current Kelvin effect is reduced, wire 2 is by multiply
The gluing of copper wire 3 forms.
In the present embodiment, in order to protect wire 3, the mechanical stability and insulating properties of the utility model cable are improved,
Cable core also includes rubber filling layer 4, and rubber filling layer 4 is filled inside the second protective layer 13, the space between wire 2.Due to rubber
The presence of glue packed layer 4, the cross section of cable core could be arranged to circle, so as to be that the resistance of cable is minimum, transmit electric energy
During loss it is minimum, also can further improve the impact resistance of cable core.
Shock resistance low temperature resistant cable of the present utility model, sheath include three-decker, and wherein intermediate layer is polyaryl fiber
Layer, have tensile strength height, wettability, dimensionally stable, heat-resisting good, wear-resisting, cut resistant, acidproof, impact resistance, flame resistance excellent etc.
Advantage, ensure the reliability of cable cover(ing).Meanwhile wire includes four, wherein three axial axis settings triangular in shape, in addition
A piece wire is arranged in the space between three wires, and the cable of the structure has good impact resistance and lower temperature resistance,
In order to ensure that cable still has good pliability at low temperature, avoid causing cable brittle failure during low-temperature bending, in wire also
It is provided with flexible lines.Therefore, the utility model cable has the advantages of reliability is high, and shock resistance resistance to low temperature is good.
The utility model case study on implementation is these are only, is not limited to the utility model, as long as this area is common
The equivalent modification or change that technical staff is made according to the utility model disclosure, should all be included described in claims
Protection domain in.
