Abstract
The utility model discloses a novel armored cable structure applied to the technical field of cables. The armored cable structure comprises an inner cable core, armored steel belts and an outer sheathing layer, wherein, the three layers of the spiral armored steel belts are coated on the surface of the inner cable core in an isometric and overlapping manner, 1/2 of the armored steel belts are overlapped; preferably, the thickness of the first layer armored steel belt is half of that of the armored steel belt in the prior art, while the thicknesses of both the second and the third armored steel belts remain the same, so the extrusion and damage of the steel belts to the bent part of the cable can be reduced, and accordingly, the safety and durability are enhanced.
Description
Technical field
The utility model belongs to the cable technology field, relates in particular to a kind of NEW TYPE OF COMPOSITE armoured cable.
Background technology
Cable is meant by the conductor outsourcing insulation and the protective layer of one or more mutually insulated and processes; With electric power or information from one be transferred to another place lead; Belong to indispensable high-risk product in the present age, as protect improper meeting and cause very big loss, so the protective layer of cable is of crucial importance.At present protect steel-tape armouring commonly used to adopt two-layer steel band, twine, make top one deck steel band cover the space of lower floor's steel band equably with the equidistance spiral form that opens wide with less pitch to cable.
Cable armouring adopts the wrapped structure that double-deck ribbon spiral twines at present, and its longitudinal section is referring to Fig. 1, and cable inner core 1 surperficial equidistance twines ground floor steel band 2 and second layer steel band 3.Steel band is that the cable inner core that is twined provides the armor protection; Mainly contain three kinds of effects; First can prevent that the cable inner core from suffering the direct destruction of sharp weapon such as spade and pick, second can muroid and termite to directly the biting of cable inner core, the 3rd provides electric shield for cable inside.But the form that this double-deck ribbon spiral twines has two-layer protection at overlapping part, has only layer of protecting at non-overlapped position, therefore in order to reach the effect of armouring, requires each layer steel band all thicker, and thickness of strips commonly used at present is 0.5 millimeters thick.Though the steel band of thickness has been obtained good effect aspect armouring like this, because the rigidity of steel band is big, make cable in the process of bending, armouring is difficult to deformation, causes the bending radius of cable to become big, has increased the difficulty of cable construction; Secondly, the workmen tends to cable too crooked in order at small-bend radius cable to be installed.The longitudinal section of crooked position is referring to Fig. 2, and ground floor steel band 2 can not deformation and insert cable inner core 1, is prone to cause faults such as electric leakage or puncture.
In sum, be necessary the cable armouring of this double-layer spiral winding steel is improved.
Summary of the invention
To above-mentioned defective; The utility model provides a kind of cable of novel wrapped structure; The adverse effect of bringing when its purpose is to reduce because of the rigidity of armouring itself installation of cable and utilization can not receive extraneous destruction by better protection cable inner core simultaneously, strengthens its durability.
To achieve these goals, said novel armoured cable structure comprises cable inner core, cable armouring and external sheath layer.
Above-mentioned cable inner core conductor material is a stranded copper wire.
Above-mentioned cable inner core insulating layer material is polyethylene or polyvinyl chloride.
Above-mentioned cable inner core comprises the filling plastic material.
Above-mentioned cable inner core comprises strand wire.
Above-mentioned cable armouring is the wrapped structure of compound steel band equidistance spiral.
The ground floor thickness of strips of above-mentioned cable armouring is 1/2nd of original technological thickness of strips.
The second layer of above-mentioned cable armouring and compound steel tape thickness equal original technological thickness of strips.
Above-mentioned cable jacket layer material is polyethylene or polyvinyl chloride.
The utility model is compared the outstanding advantage of present technology:
The armoured cable structure of the utility model; Because the later applying cable of said ground floor armouring tape attenuation inner core is tightr; At the crooked position of cable, said ground floor cable can be out of shape along with the bending of cable, is unlikely to puncture the insulating barrier of inner core; Stop second layer cable directly to destroy and pierce through the insulating barrier of cable inner core simultaneously, guarantee the security performance of cable at crooked position.
Description of drawings
Fig. 1 is the cable longitudinal section sketch map that the double-deck ribbon spiral of prior art twines armouring;
Fig. 2 be the double-deck ribbon spiral of prior art twine armouring cable in the longitudinal section of crooked position sketch map;
Fig. 3 representes that the compound steel band spiral of the utility model twines the cable longitudinal section sketch map of armouring.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.See also Fig. 3.
The structure of the utility model armoured cable comprises cable inner core, cable armouring and external sheath layer.
Above-mentioned cable inner core 1 comprises strand wire and packing material.
The equidistance spiral is wrapped forms by ground floor steel band 10, second layer steel band 20 and compound steel band 30 for above-mentioned cable armouring 2.
Above-mentioned cable armouring 2 is identical with compound steel band 30 width by ground floor steel band 10, second layer steel band 20.
The thickness of the ground floor steel band 10 of above-mentioned cable armouring 2 is 1/2nd of prior art thickness of strips.
The second layer steel band 20 of above-mentioned cable armouring 2 and the thickness of compound steel band 30 equal the thickness of prior art steel band.
Evenly overlapping each other between the compound steel band of above-mentioned cable armouring 2, overlapping area is 1/2nd of an individual layer steel band area.
The above-mentioned cable armouring 2 outside one deck external sheath layers 4 that coat.
Above-mentioned cable armouring 2 is with respect to prior art, and the ground floor steel band 10 that has increased one deck reduced thickness is close to the cable inner core; Because after the attenuation of ground floor steel band, flexible increasing makes steel band to deform along with the bending of inner core, is unlikely to puncture the insulating barrier of inner core; Simultaneously, at the crooked position of cable, ground floor steel band 10 can stop the direct compressing of 20 pairs of cable inner cores of second layer steel band, and protection cable inner core is not punctured by armouring tape.
In sum; The utility model is through the structure of the armoured cable of change prior art; Specifically be the number of plies that increases the armoured cable steel band, increased the flexibility of innermost layer armouring tape, bring better protection for the cable inner core; Especially avoided the extruding of steel band at the cable crooked position, offered convenience for the construction and the application of armoured cable the cable inner core.
Certainly; The utility model also can have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
