Utility model content
For solving the technical problem existed in background technology, the utility model proposes a kind of warp resistance distortion power cable, its warp resistance performance is good.
A kind of warp resistance distortion power cable that the utility model 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, metal armor layers adopts that zinc-plated nickel wire is stranded to be made.
Preferably, screen adopts tinned copper wire braiding to make.
Preferably, elastic cord breaker adopts silicon rubber to make.
Preferably, restrictive coating employing ceramic silicon rubber extrudes and forms.
The warp resistance distortion power cable that the utility model 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 distortion power cable that the utility model 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
