Abstract
The utility model relates to a 0.6/1KV power cable special-shaped conductor insulating wire core capable of avoiding torsion stress, which comprises a special-shaped conductor (1). The special-shaped conductor (1) comprises uniconductor wires which are polymerized from inside to outside, a stranded torsion direction of the uniconductor wire on the outermost layer of the special-shaped conductor (1) is right and coincided with the direction of cable forming, and the stability of the conductor is ensured in cable forming. Stranded torsional pitches correspond to a cable forming pitch. The power cable special-shaped conductor insulating wire core aims to eliminate insulation cracking of a cable and improves the cable forming appearance of the cable.
Description
Technical field
The utility model belongs to 0.6/1kV power cable special-shaped conductor field, particularly relates to a kind of 0.6/1kV power cable special-shaped conductor insulated wire cores of avoiding distorting stress.
Background technology
Be the use that industry or Agricultural Development all be unable to do without electricity, the 0.6/1kV power cable is used very general.Its conductor insulation core is divided into two kinds by shape at present, and a kind of is circular, and another kind is an abnormity.Technology controlling and process and the operation of round conductor insulated wire cores when insulating exruded and multicore stranding is comparatively simple, but the gap during round insulation core stranding is very big.In order to guarantee the outward appearance rounding of finished cable behind the stranding, need to use a large amount of packing materials to fill the gap, and conductor assembly outer diameter is very big, the consumption of cable auxiliary material and outer sheath material also increases accordingly, and the cables manufacturing cost is higher.And the special-shaped conductor insulated wire cores is when stranding, need hardly to fill, not only significantly reduce packing material, the cable core roundness also can be better, and conductor assembly outer diameter is also corresponding reduces, and the consumption of outer sheath material also can reduce accordingly, can also reduce packaging tray tool size simultaneously, minimize transport costs, reduced manufacturing, packing, the cost of transportation of cable enterprise.Therefore, the 0.6/1kV power cable that at present nearly all cable enterprise produces, more than a uniform section, the conductor insulation core all adopts polymorphic structure.
No matter be circle or special-shaped conductor insulated wire cores, reversing of self all arranged when stranding is stranded, distorting stress is very big.Conductor outermost layer strand is to being left-hand in addition, and the stranding direction dictates is a dextrad, and self distorting stress makes the outermost layer monofilament loose, causes the damaged cracking of insulating surface easily.Thereby the round conductor insulated wire cores all must use back twist to eliminate the distorting stress of self when stranded, do not have a technology difficult problem.And the special-shaped conductor insulated wire cores can't solve distorting stress easily, occurring insulated wire cores during stranding easily stands up, the phenomenon of the damaged cracking of insulating surface appears in cable easily in production and client's use, when especially using the organosilane crosslinked polyethylene insulation, because silane crosslinked polyethylene is a thermosets, its material is more than polyvinyl chloride hard, does not reduce the internal stress that insulated wire cores produces because of torsion, the easier insulation cracking of causing influences useful life of product.And along with the continuous development of society, people constantly strengthen the consciousness of environmental protection, having accelerated people uses the organosilane crosslinked polyethylene insulation to replace the paces of polyvinyl chloride insulation, how to improve 0.6/1kV power cable special-shaped conductor insulated wire cores cabling process, urgent necessity that the solution insulating surface just becomes because of the damaged problem that ftractures of distorting stress.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of 0.6/1kV power cable special-shaped conductor insulated wire cores of avoiding distorting stress, with the problem of the stranding outward appearance of the insulation cracking phenomena that solves cable in the prior art, cable.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of 0.6/1kV power cable special-shaped conductor insulated wire cores of avoiding distorting stress is provided, comprise the special-shaped conductor of forming by the polymerization from inside to outside of uniconductor silk (1), the stranded torsional direction of the outermost layer uniconductor silk of described special-shaped conductor (1) is a dextrad, consistent with the stranding direction, the stability of conductor when guaranteeing stranding.
It is described that stranded to reverse pitch corresponding with laying up pitch.
When extrusion molding insulation, the insulated wire cores stranding after crosslinked, when round conductor insulated wire cores stranding, use back twist to eliminate the distorting stress of self.
Beneficial effect
After using the utility model, do not need to increase the manufacture difficulty of producing conductor and extrusion molding insulation operation and reduce its production efficiency.When stranding, need not carry out pretwist to insulated wire cores, do not have twisting pitch in the time of can not causing pull head and cause core to stand up and crawl curved, pull head is easier, saved the production time, the cable of production is rounding more, has thoroughly eliminated the distorting stress of stranding and has caused the insulation cracking phenomena because of it.
Description of drawings
Fig. 1 is the special-shaped conductor insulated wire cores finished product sectional view of prior art.
Fig. 2 is a special-shaped conductor insulated wire cores finished product sectional view of the present utility model.
Wherein: 1-special-shaped conductor, 2-insulator, 3-sheath.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 2, the direction of lay of special-shaped conductor outermost layer monofilament becomes dextrad by existing left-hand, and is consistent with the stranding direction, the stability of conductor when guaranteeing stranding; When producing special-shaped conductor, whole conductor is carried out preform, also just conductor self is reversed earlier to the right according to certain pitch, it is corresponding with laying up pitch to reverse pitch, when extrusion molding insulation, the insulated wire cores stranding after crosslinked, as round conductor insulated wire cores stranding, use back twist to eliminate the distorting stress of self.
We manufacture experimently and have produced 520 meters of YJV-0.6/14 * 240 power cables, special-shaped conductor 1 preform pitch 2140 ± 30mm wherein, pitch 2140 ± 30mm during special-shaped conductor insulated wire cores stranding, actual laying up diameter Φ 46.2 ± 0.3mm, laying up diameter f value is less than 0.5mm.Insulated wire cores did not have the phenomenon of standing up during trial-production was produced, and did not have snakelike curved phenomenon, and the naked cracking phenomena has had obvious improvement than before, checked through behind the finished product, and all performances satisfy standard-required, have reached Expected Results.
