Abstract
The invention discloses a dragging-resistant grinding-resistant mobile cable. The dragging-resistant grinding-resistant mobile cable comprises a cable core, a cable core wrapped belt layer, an outermost layer wrapped outer protective sleeve, wherein the cable core consists of a plurality of insulated cable cores and a saddle-shaped filling strip for isolating the insulated cable cores; each insulated scale core consists of a conductor and an insulated layer wrapped outside the conductor. The dragging-resistant grinding-resistant mobile cable is high in softness, high in bending resistance, high in tensile performance and dragging resistance, and can be completely suitable for characteristics of being frequent to move, easy to grind, and the like.
Description
Technical field
The present invention relates to electric wire field, refer in particular to and a kind of resistance toly pull rolling resistance removal cable.
Background technology
Removal cable use occasion is very extensive, be most widely used in building industry, industry, in actual use, cable is often laid in does not have the place of attached cable groove, and on-site, this kind of cable needs according to different service conditions, change place to use, and the mode of laying adopts manually, therefore this kind of cable needs good bending property, pulls performance good.Inevitably rolled by people, car or other equipment when cable uses on-site, therefore cable will have rolling resistance performance.In order to ensure above-mentioned requirement, in use, adopt mainly by strengthening management in the environment of common cable, the careful cable that uses realizes.Some places then adopt by the cable of metal armouring to realize the function of the rolling resistance of cable.
Prior art Problems existing and shortcoming:
Adopt common removal cable, although the bending property of cable is fine, conveniently still lay, inside does not have reinforcement, and cable very easily damages in roller compaction process, and then impact uses.And adopt the cable of metal armouring very outstanding at anti-rolling aspect of performance, but its heavier-weight, and bending property is very poor is inconvenient to lay, and have the cable cost of metal armouring higher.
Summary of the invention
Technical problem to be solved by this invention is to overcome prior art defect, and provide a kind of soft high, resist bending performance is high, high tensile, resistance to pull performance can adapt to completely mobile frequent, be subject to the removal cable that rolls.
In order to solve the problems of the technologies described above, the invention provides and a kind of resistance toly pull rolling resistance removal cable, comprise cable core, the outer wrapped belting layer of cable core, outermost layer extrudes oversheath; Described cable core is made up of some insulated wire cores and the saddle type packing of insulated wire cores being kept apart.
Further improvement, described insulated wire cores is made up of conductor and the insulating barrier be extruded in outside conductor.
Further improvement, described saddle type packing is made up of the aramid yarn at center and the saddle type rubber bar be extruded in outside aramid yarn.
Further improvement, described saddle type rubber bar is provided with multiple rubber band ridge, forms groove insulated wire cores separated between every two rubber band ridges.
Further improvement, described conductor is formed together with aramid yarn closing lay by monofilament.
Further improvement, described rubber band ridge width is 2.5-4mm.
Beneficial effect of the present invention is:
1, the present invention adopt in the structure choice of conductor, select multiply thin copper wire lay configuration, when strand bundle twists, per share center adds high strength aramid yarn, and monofilament, together with aramid yarn closing lay, effectively can improve bending resistance, the tensile strength of sub-thread.After twist together per share according to regular structure, effectively can improve the bending resistance of conductor, tensile strength.It is high that reinforced aramid yarn has intensity, and density is little, soft feature, less on conductor weight impact.
2, during core stranding, a saddle type packing is placed at center, and for convenience of extrusion molding and the tensile property increasing saddle type bar of saddle type bar, its center can with the aramid yarn of a high strength as center-filled; The muscle ridge width of saddle bar is that 2.5-4mm is advisable, and saddle type bar body and muscle ridge adopt the insulation rubber that adapts with cable Long-term service temperature or semi-conductive rubber to extrude; Saddle bar it by no for each core separately separately, be placed in respective groove, when cable is squeezed, the various piece of cable is all independently separately independent of each other mutually, enhances the ability of rolling resistance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated.
As shown in Figure 1, one of the present invention is resistance to pulls rolling resistance removal cable, comprises cable core, the outer wrapped belting layer 5 of cable core, and outermost layer extrudes oversheath 6; Described cable core is made up of some insulated wire cores and the saddle type packing of insulated wire cores being kept apart; Described insulated wire cores is made up of conductor 1 and the insulating barrier 2 be extruded in outside conductor 1.
Described saddle type packing is made up of the aramid yarn 3 at center and the saddle type rubber bar 4 be extruded in outside aramid yarn; Described saddle type rubber bar 4 is provided with multiple rubber band ridge, forms groove insulated wire cores separated between every two rubber band ridges;
Described conductor 1 is formed together with aramid yarn closing lay by monofilament; Described rubber band ridge width is 2.5-4mm.
Operation principle of the present invention or the course of work:
1, in the structure choice of conductor, select multiply thin copper wire lay configuration, when strand bundle twists, per share center adds high strength aramid yarn, and monofilament, together with aramid yarn closing lay, effectively can improve bending resistance, the tensile strength of sub-thread.After twist together per share according to regular structure, effectively can improve the bending resistance of conductor, tensile strength.It is high that reinforced aramid yarn has intensity, and density is little, soft feature, less on conductor weight impact.
2, during core stranding, a saddle type packing is placed at center.For convenience of extrusion molding and the tensile property increasing saddle type bar of saddle type bar, its center can with the aramid yarn of a high strength as center-filled; The muscle ridge width of saddle bar is that 2.5-4mm is advisable, and saddle type bar body and muscle ridge adopt the insulation rubber that adapts with cable Long-term service temperature or semi-conductive rubber to extrude.Saddle bar as shown in the figure, it by no for each core separately separately, be placed in respective groove, when cable is squeezed, the various piece of cable is all independently separately independent of each other mutually, enhances the ability of rolling resistance.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be considered as protection scope of the present invention.
