Description

A kind of tensile cable

Technical field

The present invention relates to a kind of cable, more particularly, it relates to a kind of tensile cable.

Background technology

Now cable is to strengthen its pull resistance, using more enhancing structures be cable into It is squeezed into and electricity by aramid fiber, the rope made of hemp or directly using insulating materials inferior is solid during cable The circular lines of the equal external diameter of cable core stranded circular configuration for becoming an entirety in stranding, Or use the enhanced anisotropic approach of steel wire rope in the one or both sides of oversheath.Above-mentioned this kind of knot Structure respectively has quality, and preferable state is not reached when in use.Using the rope made of hemp and the cable of fiber Structure, is far from using the intensity of steel wire good in intensity, also poor than others on the life-span. And aramid fiber is not water-fast, on the other hand, if very big into the gap between cable core, in order to protect The rounding property of card cable, needs to fill the substantial amounts of rope made of hemp and string, and the rope made of hemp and fiber All be the multiply rope made of hemp composition in usage amount be difficult control.Using insulation inferior or sheath material The hatching solid circle bar of extrusion is strong without the rope made of hemp and fiber in intensity.And use outside steel Silk is enhanced, finds when actually used, and one side uses the cable of steel wire rope, in other side Because long-time is affected by gravity, cable still can extend, and use time is longer, prolong Stretch more severe, in order to overcome this shortcoming, devise both sides all carried out using steel wire rope it is enhanced Although enhancing structure, this structure improves the problem of a cross hang but also increases and be manufactured into This, and this enhancing simply enhances cable jacket, and also the enhancing to cable core is made With simultaneously less.

The content of the invention

In order to overcome the deficiencies in the prior art, it is an object of the invention to provide a kind of tension is electric Cable, it adopts circular configuration, efficiently solves the problems, such as cable pull resistance, and has saved manufacture Cost, is easy to large-scale promotion application.

To solve the above problems, the technical solution adopted in the present invention is as follows：

A kind of tensile cable, including conductive core, tensile members and oversheath, the conductive core Including wire and the insulating barrier being wrapped in outside wire, the tensile members include steel wire rope and are wrapped in Restrictive coating on steel wire rope, the conductive core and tensile members constitute inner core, the oversheath bag It is rolled on inner core, the oversheath section is circle.

Preferably, also including twining package tape, the twining package tape is spirally wound on inner core, positioned at outer Between sheath and inner core.

Preferably, the twining package tape width D be less than conductive core diameter, adjacent twining package tape it Between spacing L be not more than twining package tape width D.

Preferably, angle α is 30 °～75 ° between the twining package tape and cable tracer.

Preferably, the steel wire rope is tin plating flexible wire ropes.

Preferably, the restrictive coating is nylon material.

Preferably, the conductive core is identical with tensile members diameter, and the inner core is by conductive core It is arranged in parallel with tensile members to form.

Preferably, it is additionally provided with cushion between the steel wire rope and restrictive coating.

Preferably, the cushion is isolation material.

Preferably, the conductive core is identical with tensile members diameter, and the inner core is by conductive core Form with tensile members twisting.

Compared to existing technology, the beneficial effects of the present invention is：It adopts circular configuration to the present invention, Cable pull resistance is efficiently solved the problems, such as, and has saved manufacturing cost, be easy to large-scale promotion Using.

Using circular configuration, make cable more attractive in appearance, and round cable area occupied in upper disk It is less than the area occupied of anisotropic approach, run into poling wiring circular configuration and be more prone to pass through.

Strengthened using zinc-plated flexible wire ropes, zinc-plated flexible wire ropes are placed into cable Side, many core reinforced cables smaller for section are directly extruded on zinc-plated flexible wire ropes Cotton garment layer, makes cotton garment layer be wrapped in zinc-plated flexible wire ropes surface, and nylon material has From skidding effect, core is not damaged in cable is moved back and forth；For core section compared with Big cable, in the outer extruding insulation cushion of zinc-plated flexible steel wire, squeezes on the outside of insulating buffer layer The form of pressure cotton garment layer, the external diameter for making tensile members reaches the equal external diameter of conductive core, into Jing is twisted into inner core during cable, and such structure constitutes the core uniform force of inner core, deformation force It is concentrated on intensity highest core, that is, on zinc-plated flexible wire ropes, it is ensured that cable Overall pull resistance.

By the setting of twining package tape, when extrusion oversheath, sheath material can penetrate into not around Where wrapping twining package tape, so that sheath itself forms a spiral helicine inner surface, so Gravity suffered by oversheath will be dispersed on the core of stranding, solve the gravity shadow of core Ring, so as to ensure that the integrally-built stability of cable.
