Abstract

The utility model relates to a high flexible torsion-resistant tension-resistant cable. A cable central layer adopts twisted high strength fiber cores or high strength fibers and insulated wire cores which are laid at intervals to form the cable. The cable has good flexibility, high strength and light weight, is capable of effectively avoiding damage to the cable caused by self weight and steel wires, saving fillings, simultaneously improves heat dissipation performance of the cable, improves current-carrying capability of the cable, reduces weight of the cable and is convenient for users to transport and lay.

Description

The anti-tension cable of turning round of high flexibility

Technical field

The utility model relates to a kind of multiple core cord cable, the anti-tension cable of turning round of particularly a kind of high flexibility.

Background technology

At present, continuous development along with China's boats and ships, harbour, mine, rolling stock, for security consideration, require more and more higher to these industry facilities, cable plays important effect therein, should guarantee enough flexibilities at these occasion cables, possess very strong tensile strength again.At present mainly based on following dual mode: a kind of serves as to adopt braided steel wire to strengthen, this mode cable causes the steel wire fracture of wire easily in frequent moving process, just in case fracture of wire might be dampened insulation, thereby cause short circuit, steel wire is a rigid material in addition, cable uses in frequent mobile occasion, produces friction, the scratch of will insulating easily between steel wire and the insulation; Another kind of with the insulated wire cores stranding, this cable tensile property is better for general employing steel strand wire are squeezed into one deck insulation (or not squeezing), but flexibility is relatively poor, can not frequently move for a long time, also causes easily to insert between the core and hinders.

In addition in normal cable is arranged, according to the cable twisting rule, single line core or several threads core can be put in general center, and in stranded process general intermediate layer not stranded (situation), perhaps the stranded lay ratio of internal layer is greater than outer pitch, thereby cause the intermediate layer bending relatively poor, in mobile BENDING PROCESS, rupture easily in the intermediate layer.

The utility model content

The purpose of this utility model is to overcome the deficiency of above-mentioned cable and provides a kind of flexibility good, has higher-strength, can bear the flexible anti-tension cable of turning round of certain pulling force.

The technical scheme that realizes the utility model purpose is:

The anti-tension cable of turning round of a kind of high flexibility comprises conductor, insulated wire cores and extruding restrictive coating, also has one or some high-intensity fiber cores, and described high-intensity fiber core places cable center or places the cable periphery with the stranding arrangement of described insulated wire cores interval; Described high-intensity fiber core adopts a branch of or a branch of above stranded forming, and wherein every bundle forms by glass fibre, basalt fibre or carbon fiber are stranded; The anti-tension cable of turning round of described high flexibility also has the soft packed layer that places cable center.

The utility model has guaranteed that by the setting of high-intensity fiber core cable can bear certain pulling force in running; The size of central core is subjected to what the constraint of design strength and outside core, and the multiple strand of well-regulated bundle strand of core or bundle strand back together, guaranteed certain intensity and certain flexibility; Because the high-intensity fiber core is a flexible material, it in use can not damage insulated wire cores, thereby has guaranteed the insulation property of cable simultaneously.Its advantage is: flexibility is good, the intensity height, and cable weight is little, can effectively prevent cable deadweight and the steel wire destruction to cable, can save filling again, simultaneously, improve the heat dispersion of cable, improved the current capacity of cable, cable weight reduces, give the user transportation, lay and bring convenience.

Embodiment

(embodiment 1)

Referring to Fig. 1 and Fig. 2, the anti-tension cable of turning round of a kind of high flexibility of present embodiment is followed successively by from inside to outside: single bundle high-intensity fiber core 1, conductor 2, insulated wire cores 3, extruding restrictive coating 4, single bundle high-intensity fiber core is by glass fibre or basalt fibre or carbon fiber is stranded forms, and its Haul Rate is identical.According to the external diameter and the fiber material of the number of outside core, core external diameter and its required pulling force design internal fiber core that bears, insulated wire cores 3 radicals are not limit.

(embodiment 2)

Referring to Fig. 3, a kind of high flexibility of present embodiment is anti-, and to turn round the tension cable substantially the same manner as Example 1, and difference is that the center bears the high-intensity fiber core 1 of pulling force and form by multi beam is stranded.

(embodiment 3)

Referring to Fig. 4, a kind of high flexibility of present embodiment is anti-, and to turn round the tension cable substantially the same manner as Example 1, difference be to have the high-intensity fiber core 1 that places cable center and with the insulated wire cores 3 high-intensity fiber core 1 arranged of strandings at interval.

(embodiment 4)

Referring to Fig. 5, a kind of high flexibility of present embodiment is anti-, and to turn round the tension cable substantially the same manner as Example 1, difference be high-intensity fiber core 1 and insulated wire cores 3 at interval strandings arrange, increase the soft packed layer 5 of cable in the middle of the cable.

Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is a specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
