Abstract
The invention discloses a light bend-resistant cable which comprises an outer sheath, a strengthening protective layer, a conductor and a rubber pipe, wherein the rubber pipe is a hollow pipe made of rubber materials; a nylon strengthening net sleeve is pre-embedded into the wall of the rubber pipe; conductors are respectively arranged at the periphery of the rubber pipe; the strengthening protective layer wraps the outer sides of the conductors, and is an overlapped wrapping non-woven fabric tape; and the outer sheath is arranged outside the strengthening protective layer. By adopting the mode, the light bend-resistant cable disclosed by the invention has the advantages of good bend-resistant property, light weight and high tensile strength by substituting the overlapped wrapping non-woven fabric tape for a metal tape on the strengthening protective layer, and can be used for protecting the conductors from being damaged when the conductors are extruded and impacted through reasonable deformation by having good elastic deformation capacity, thus achieving easiness in bending, good durability and flexibility and convenience in construction.
Description
Technical field
The present invention relates to field of cables, particularly relate to a kind of lightweight resist bending cable.
Background technology
Wires and cables industry is the second largest industry being only second to automobile industry in China, and the electric wire gross output value exceedes the U.S., becomes first electric wire producing country in the world.
The main material of cable is metallic conductor and sheath, the deadweight of conductor itself is comparatively large, and arranges metal tape in conductor periphery, and in order to improve the tensile strength of cable, partial cables also add steel wire strengthening core, the deadweight of cable is also risen thereupon, brings difficulty to the laying of cable, and the requirement arranged ground supports is higher, and it is not flexible, add the difficulty of construction, more there is no the ability of deformation buffer, easily rupture in extruding.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of lightweight resist bending cable, and lightweight, tensile strength is high, and deformation behavior is good, resist bending.
For solving the problems of the technologies described above; the technical scheme that the present invention adopts is: provide a kind of lightweight resist bending cable; comprise: oversheath, heavy seal coat, conductor and rubber tube; described rubber tube is the hollow pipe of quality of rubber materials; be embedded with nylon in the tube wall of described rubber tube and strengthen net; described conductor is separately positioned on around rubber tube; described heavy seal coat is wrapped in the outside of conductor; described heavy seal coat is attached most importance to the nonwoven fabric belts of lap wound bag, and described oversheath is arranged on the outside of heavy seal coat.
In a preferred embodiment of the present invention, the outside of described conductor is respectively arranged with PVC insulating barrier.
In a preferred embodiment of the present invention, in the space between described heavy seal coat and PVC insulating barrier, be also provided with the cable cream that blocks water.
In a preferred embodiment of the present invention, described oversheath is linea low density black polyethylene sheath.
In a preferred embodiment of the present invention, described heavy seal coat comprises the wrapped nonwoven fabric belts of at least one ply.
The invention has the beneficial effects as follows: a kind of lightweight resist bending cable that the present invention points out; heavy seal coat adopts overlapping wrapped nonwoven fabric belts to instead of metal tape, and resist bending performance is good, lightweight; be embedded with nylon in the tube wall of rubber tube and strengthen net; tensile strength is high, and elastic deformability is good, when being squeezed and impact; conductor is protected to escape injury by being reasonably out of shape; be more prone to bending, durability is good, easy construction.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of a kind of lightweight resist bending of the present invention cable one preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, oversheath, and 2, heavy seal coat, 3, conductor, 4, rubber tube, 31, PVC insulating barrier.
Embodiment
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of lightweight resist bending cable, comprise: oversheath 1, heavy seal coat 2, conductor 3 and rubber tube 4, described rubber tube 4 is the hollow pipe of quality of rubber materials, be embedded with nylon in the tube wall of described rubber tube 4 and strengthen net, compared with steel wire strengthening core, rubber tube 4 both ensure that intensity, alleviate weight again, and the ability of strain is good, more resist bending, when being clashed into and extrude, good to the protectiveness of conductor 3, described conductor 3 is separately positioned on rubber tube 4 around, described heavy seal coat 2 is wrapped in the outside of conductor 2, described heavy seal coat 2 is attached most importance to the nonwoven fabric belts of lap wound bag, compared with metal tape, overlapping wrapped nonwoven fabric belts is lightweight, cost is low, and be more easily tailored and peel off during construction, reduce difficulty of construction, described oversheath 1 is arranged on the outside of heavy seal coat 2.
A kind of lightweight of the present invention resist bending cable has PVC insulating barrier 31 in the outer setting of described conductor, good to the protectiveness of conductor.
Further, be also provided with the cable cream that blocks water in the space between described heavy seal coat 2 and PVC insulating barrier 31, prevent the invasion of current.
Further, described oversheath 1 is linea low density black polyethylene sheath, has waterproof and abrasive resistance.
Further, described heavy seal coat 2 comprises the wrapped nonwoven fabric belts of at least one ply, in order to improve the effect of tension, suitably can increase the number of plies of overlapping wrapped nonwoven fabric belts.
In sum, a kind of lightweight resist bending cable that the present invention points out, compared with traditional cable, on the basis ensureing resistance to tensile strength, reduce deadweight, improve resist bending and shock proof ability, construct convenient, be more applicable to various complications, complicated field of employment.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
