Abstract
The invention belongs to the technical field of cables and electric power and especially relates to an anti-torsion cable. The anti-torsion cable comprises a plurality of insulating wires and a sheath layer covering the insulating wires. Each insulating wire is composed of a conductor and an insulating layer covering the conductor. The anti-torsion cable is characterized in that the adjacent insulating layers are connected through connection ribs, and the sheath layer is in surface contact or double-wire contact with each insulating wire. The anti-torsion cable mainly has the advantages that the anti-torsion performance is good, the number of production devices is fewer, the place used for production is smaller, the manufacturing cost is lower, and the product cost is lower.
Description

In the present invention, insulating barrier link is integrated by dowel；When having connector, insulating barrier is integrated by connector with restrictive coating link；Substantially increase the torsional property of cable.
In the present invention, insulating barrier link is integrated by dowel；In time without connector, owing to restrictive coating and each insulating barrier contact surface are two planes, limit the rotation of insulating barrier and restrictive coating, therefore substantially increase the torsional property of cable.
In the present invention, insulating barrier link is integrated by dowel；In time without connector, owing to restrictive coating and each insulating barrier contact position are doublet contact, limit the rotation of insulating barrier and restrictive coating equally, therefore substantially increase the torsional property of cable.
Certainly, in the present invention, it is also possible to the gap between insulating barrier, between insulating barrier and restrictive coating arranges filler, the torsional property of cable is made to strengthen further.
Three preferred embodiment examples in the present invention, torsion contrast test has been carried out with cable of the prior art, under same experimental condition, the cable of the present invention, standing 3000 times, after ± the long run test of 360 degree, does not occurs that situation that cable core loosens, conductor have no that deformation, current-carrying capacity are not changed in yet.；And cable of the prior art is standing 200 times, after ± the long run test of 360 degree, situation that intertwist body reverses and conductor gross distortion are occurred as soon as, current-carrying capacity have dropped 50%.
The present invention need not the stranded equipment of insulator in producing, and artificial, electricity, the Revolving disc that therefore save stranded operation and the input of stranded equipment, stranded needs have, have enough to meet the need region etc.；The insulating barrier that only need to production be completed produces in restrictive coating production process and can be prepared by cable.
Therefore, the present invention has following main beneficial effect: torsional property is more excellent, it is less to produce equipment, production place is less, manufacturing cost is lower, product cost is lower.
