Abstract

The invention belongs to the technical of cables and electric power, and particularly relates to a torsion-resistant cable. The torsion-resistant cable comprises a plurality of insulated wires and jacket layers coating the insulated wires, wherein each insulated wire consists of a conductor and an insulation layer coating each conductor. The torsion-resistant cable is characterized in that the adjacent insulated layers are connected through connecting ribs, and each jacket layer is in surface contact or double-line contact with each insulated wire. The torsion-resistant cable has the main benefits as follows: the torsion-resistant cable is excellent in torsion resistance, less in production equipment, fewer in production field, lower in manufacturing cost and lower in product cost.

Description

A kind of anti-torsion cable
Technical field
The invention belongs to cable and power technology field, especially relate to a kind of anti-torsion cable.
Background technology
In prior art, the insulated wire that multicore cable normally comprises insulation core wire by many inside carries out the stranded formation intertwist body of one-way spiral, what then outside intertwist body, the coated restrictive coating of extrusion molding formed; The intertwist body of this cable is cylindrical, and every insulated wire and restrictive coating in intertwist body are tangent, and every insulated wire forms single line with restrictive coating and contacts.Cable in the time of built on stilts use and the time of laying, can constantly be reversed such torsion, for restrictive coating more loose with intertwist body coordinate time, when meeting there is relative rotation with restrictive coating in intertwist body, and severe patient can affect the performance of electrical cables, even causes cable conductor distortion, fracture.
Summary of the invention
In order to address the above problem, object of the present invention discloses a kind of anti-torsion cable, and it is realized by the following technical solutions.
A kind of anti-torsion cable, it includes many insulated wires, envelopes the restrictive coating of insulated wire, and insulated wire is made up of conductor, the insulating barrier that envelopes conductor, it is characterized in that connecting by dowel between adjacent insulating barrier; Restrictive coating is that face contacts or doublet contact with every insulated wire.
A kind of anti-torsion cable described above, is characterized in that between described restrictive coating and every insulated wire, having one or two intercell connectors.
A kind of anti-torsion cable described above, is characterized in that described restrictive coating and every insulated wire are faces while contacting, and contact-making surface is single or double.
A kind of anti-torsion cable described above, the inwall that it is characterized in that described restrictive coating is not cylindrical side.
A kind of anti-torsion cable described above, is characterized in that described insulated wire is cuboid or the cylinder shape of cuboid or unfilled corner.
A kind of anti-torsion cable described above, is characterized in that the inner surface of described restrictive coating has multiple planes.
A kind of anti-torsion cable described above, the material that it is characterized in that described conductor is copper or aluminium or alloy.
A kind of anti-torsion cable described above, the material that it is characterized in that described insulating barrier is polyethylene or polypropylene or polyvinyl chloride or low-smoke halogen-free polyolefin.
A kind of anti-torsion cable described above, the material that it is characterized in that described dowel is polyethylene or polypropylene or polyvinyl chloride or low-smoke halogen-free polyolefin.

A kind of anti-torsion cable described above, the material that it is characterized in that described restrictive coating is polyethylene or polypropylene or polyvinyl chloride or low-smoke halogen-free polyolefin.
In the present invention, dowel links insulating barrier to be integrated; While having connector, connector is integrated insulating barrier and restrictive coating link; Greatly increase the torsional property of cable.
In the present invention, dowel links insulating barrier to be integrated; During without connector, because restrictive coating and each insulating barrier contact-making surface are two planes, limit the rotation of insulating barrier and restrictive coating, therefore greatly increased the torsional property of cable.
In the present invention, dowel links insulating barrier to be integrated; During without connector, because restrictive coating and each insulating barrier contact position are doublet contact, limit equally the rotation of insulating barrier and restrictive coating, therefore greatly increased the torsional property of cable.
Certainly, in the present invention, can also be between insulating barrier, filler is set in gap between insulating barrier and restrictive coating, the torsional property of cable is further strengthened.
Three preferred embodiment examples in the present invention, carry out torsion contrast test with cable of the prior art, under same experimental condition, cable of the present invention stand 3000 times, ± 360 degree long run tests after, do not occur that yet the loosening situation of cable core, conductor have no distortion, ampacity does not change.; And cable of the prior art is standing after 200 times, the long run tests of ± 360 degree, just occur that situation that intertwist body reverses and conductor gross distortion, ampacity have declined 50%.
The present invention does not need the stranded equipment of insulator in producing, and has therefore saved artificial, the electric weight, Revolving disc tool, turnover region of the input of stranded operation and stranded equipment, stranded needs etc.; The insulating barrier that only production need be completed is produced and can be made cable in restrictive coating production process.
Therefore, the present invention has following main beneficial effect: torsional property is better, production equipment still less, produce with place still less, manufacturing cost is lower, product cost is lower.
