Description
Technical field
The present invention relates to field of cable technology, particularly relate to a kind of warp resistance power cable.
Background technology
Electric wire refers to the material for electric power, communication and associated transport purposes, its its transmitting effect main be the conductor of electric wire inside.The conductor of traditional electric wire inside is all copper, due to copper cost higher and be country strategic resources, use copper not high as the carrier Practical Performance of electric wire.Again due to also different to the performance requirement of cable under different service conditions, existing cable warp resistance poor performance, easily break when being subject to external stress core, affects normal power communication.
Summary of the invention
For solving the technical problem existed in background technology, the present invention proposes the good warp resistance power cable of warp resistance performance.
A kind of warp resistance power cable that the present invention proposes, comprises cable core, is coated on the lapping layer of described cable core outside, is coated on the elastic cord breaker of lapping layer outside, is coated on the metal armor layers of elastic cord breaker outside, is coated on the restrictive coating of metal armor layers outside;
Cable core comprises a flexible supporting frames and three wires, flexible supporting frames by three arcs circumferentially mode be formed by connecting, arc outward opening and angle between arbitrary neighborhood two arc openings is 120 degree; Wire comprise be positioned at middle part conductor, be coated on the insulating barrier of conductor outside, be coated on the screen of insulating barrier outside, conductor is made by many scandium-aluminum alloys are stranded; Three wires are respectively against described three arc inner circumferentials, and it is becoming equilateral triangle perpendicular to the line of centres on the cross section of cable axis, is provided with halogen-free flameproof inserts, makes cable core have circular cross-section between adjacent two wires away from the 3rd wire side.
Preferably, described arc opening part end rounding off.
Preferably, the zinc-plated nickel wire of metal armor layers is stranded makes.
Preferably, screen adopts tinned copper wire braiding matter layer.
Preferably, elastic cord breaker adopts silicon rubber to make.
Preferably, restrictive coating employing ceramic silicon rubber extrudes and forms.
The warp resistance power cable that the present invention proposes, conductor is made by many scandium-aluminum alloys are stranded, reduces conductor production cost, and effectively alleviates the weight of cable.In addition, by the design to the construction of cable, on the one hand, when cable is subject to external stress effect, the arc on flexible supporting frames can alleviate by deformation the external stress that wire is subject to, reduce wire to break the risk of core, improve the warp resistance performance of cable, on the other hand, the thermoplastic elastomer (s) between wire is when cable is subject to external stress effect, the stress of adjacent wires away from cable center region can be shared by deformation, improve the warp resistance performance of cable further; Again on the one hand, elastic cord breaker can share by deformation the stress that cable core is subject to, and reduces the deformation quantity of thermoplastic elastomer (s) and flexible supporting frames, further improves the warp resistance performance of cable.The warp resistance power cable that the present invention proposes, by the design of repeatedly buffer structure, greatly enhances the warp resistance performance of cable, extends the useful life of cable.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of warp resistance power cable that the present invention proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of warp resistance power cable that the present invention proposes.
With reference to Fig. 1, the present invention proposes a kind of warp resistance power cable, the restrictive coating 7 comprising cable core, be coated on the lapping layer 4 of described cable core outside, be coated on the elastic cord breaker 5 of lapping layer 4 outside, be coated on the metal armor layers 6 of elastic cord breaker 5 outside, be coated on metal armor layers 6 outside; Elastic cord breaker 5 adopts silicon rubber to extrude and forms, and restrictive coating 7 adopts ceramic silicon rubber to extrude and forms.
Cable core comprises a flexible supporting frames 1 and three wires 2, flexible supporting frames 1 by three arcs circumferentially mode be integrally formed by connecting, arc outward opening and angle between arbitrary neighborhood two arc openings is 120 degree, described arc opening part end rounding off; Wire 2 comprise be positioned at middle part conductor 21, be coated on the insulating barrier 22 of conductor 21 outside, be coated on the screen 23 of insulating barrier 22 outside, conductor 21 is made by many scandium-aluminum alloys are stranded; Three wires 2 are respectively against described three arc inner circumferentials, and it is becoming equilateral triangle perpendicular to the line of centres on the cross section of cable axis, be provided with thermoplastic elastomer (s) 3 away from the 3rd wire 2 side between adjacent two wires 2, make cable core have circular cross-section.
In such scheme, the zinc-plated nickel wire of metal armor layers 6 is stranded to be made, and screen 23 adopts tinned copper wire to weave matter layer, and cable, while opposing external signal radiated interference and conductor opposing internal signal radiated interference, effectively enhances the intensity of cable.
The warp resistance power cable that the present invention proposes, conductor is made by many scandium-aluminum alloys are stranded, reduces conductor production cost, and effectively alleviates the weight of cable.In addition, by the design to the construction of cable, on the one hand, when cable is subject to external stress effect, the arc on flexible supporting frames can alleviate by deformation the external stress that wire is subject to, reduce wire to break the risk of core, improve the warp resistance performance of cable, on the other hand, the thermoplastic elastomer (s) between wire is when cable is subject to external stress effect, the stress of adjacent wires away from cable center region can be shared by deformation, improve the warp resistance performance of cable further; Again on the one hand, elastic cord breaker can share by deformation the stress that cable core is subject to, and reduces the deformation quantity of thermoplastic elastomer (s) and flexible supporting frames, further improves the warp resistance performance of cable.The warp resistance power cable that the present invention proposes, by the design of repeatedly buffer structure, greatly enhances the warp resistance performance of cable, extends the useful life of cable.
