Description

A kind of cable of anti-twisting stress

Technical field

Cable machinery technical field is the utility model is related to, is specially a kind of cable of anti-twisting stress.

Background technology

Cable is typically the cable of every group of at least similar rope that two conductor strands form by several or several groups of conducting wires, Mutually insulated between every group of conducting wire, and be often twisted into around a center, whole outside is surrounded by the coating of high-insulation, multi rack Be located at it is aerial or mounted in underground, the bottom, for telecommunication or power Transmission, the difference of it and common wiring be mainly cable dimension compared with Greatly, structure is more complicated.But the common cable of in the market is all there is a series of defects, for example the anti-twisting of common cable should The effect of power is not good enough, and the damage inside cable can be caused when cable distorts, so as to have impact on the use of cable, cable Nonwoven layer cladding during be usually fixed using adhesive plaster, it is such cladding not only not enough firmly and also cost It is higher, it is not practical enough the problem of, the presence of these problems all have impact on the use of in the market cable, can not meet the need used Ask, for this reason, a kind of it is proposed that cable of anti-twisting stress.

Utility model content

The purpose of this utility model is to provide a kind of cable of anti-twisting stress, to solve to propose in above-mentioned background technology Common cable anti-twisting stress effect it is not good enough, the damage inside cable can be caused when cable distorts so that The use of cable is have impact on, is usually fixed during the cladding of the nonwoven layer of cable using adhesive plaster, such bag Cover the problem of not only not firm enough but also cost is higher, not practical enough.

To achieve the above object, the utility model provides following technical solution：A kind of cable of anti-twisting stress, including copper Conductor, inner sheath and oversheath, are coated with insulating layer on the outside of the copper conductor, and non-woven fabrics is provided with the outside of insulating layer Layer, the outer wall of the nonwoven layer is fixed with locking rope, and steel-tape armouring layer is provided with the outside of locking rope, the inner sheath Inner side is mounted with steel-tape armouring layer, and the outside of inner sheath is provided with roller, and the oversheath is internally provided with roller.

Preferably, the monofilament radical of the copper conductor is 113, filament diameter 0.15mm, and the outside diameter of copper conductor is 1.84mm。

Preferably, it is to be flexibly connected between the inner sheath and oversheath and roller.

Preferably, the diameter of the roller is equal to the distance between inner sheath and oversheath.

Preferably, the locking rope is wrapped in the outer surface of nonwoven layer in polyline shaped.

Compared with prior art, the beneficial effects of the utility model are：The cable of the anti-twisting stress is provided with roller, interior Be to be flexibly connected between sheath and oversheath and roller, and the diameter of roller be equal between inner sheath and oversheath away from From oversheath can be such that roller is rolled in inner sheath when extraneous twisting stress is larger, thus by twisting stress very Good change, and the energy of twisting stress is converted into the kinetic energy of roller rolling, avoids twisting stress for cable inside Damage, ensure that the service life of cable, be provided with locking rope, locking rope is wrapped in the appearance of nonwoven layer in polyline shaped Face, locking rope very well can lock nonwoven layer, wrapped up more firmly compared to using adhesive plaster, avoid non-woven fabrics The loose situation of layer occurs, and cost is relatively low, reduces the cost of production, substantially increases the quality of cable.
