Abstract
The invention discloses a multicore extruded insulation power cable which comprises a plurality of insulation cable cores. Each insulation cable core is composed of a conductor, an insulation layer and an outer sheath, wherein the insulation layer and the outer sheath are sequentially extruded outside the conductor. The power cable is formed by connecting the outermost outer sheaths of the insulation cable cores through connecting ribs in an extruded mode. After the insulation process of all insulation cable cores is finished, a cable forming process is not carried out, extrusion of the outer sheaths continues to be carried out, when the outer sheaths are extruded, the connecting ribs between the cable cores are extruded into a whole, and through the process design, about one quarter of cable manufacturing labor cost is saved; the multicore extruded insulation power cable has the advantages that the structure is concise, the manufacturing process is simple, quality is convenient to control, cost is low, and the power cable is economical and practical and has certain popularization and application value.
Description
?
Technical field
The invention belongs to power cable field, be specifically related to a kind of multicore extrusion insulating power cable.
Background technology
Along with social development, power transmission technology is constantly progressive, and the application of various new technologies, new material emerges in an endless stream especially, just as emerged rapidly in large numbersBamboo shoots after a spring rain.Hard busy people, pursue the life of brevity and lucidity, highly effective and safe.
And the construction of cable complexity of prior art, manufacturing process's complex process, quality weight, production cost is high, the particularly common stranding operation of cable, often because of operating personnel's qualification and equipment state, easily cause the damage of product line core insulation, core insulation to scratch to press around, damage by pressure, mistake and sequence number misarrangement, insulated wire cores are stood up, laying up pitch does not conform to the rules, wire is broken by drawing-down, stranding circularity is cable snake shaped after exceeding allowed band, stranding, twining package tape gap or Duplication exceed the defects such as allowed band and affect product quality in insulated wire cores.
Summary of the invention
The object of this invention is to provide one simple for structure lucid and lively, manufacturing process is simple, and quality is convenient to control, multicore extrusion insulating power cable with low cost, economical and practical.
A kind of multicore extrusion insulating power cable of the present invention, comprises many insulated wire cores, and described insulated wire cores is by conductor and is extruded in successively insulating barrier, the oversheath outside conductor; This cable is to extrude connection moulding by the every outermost oversheath of insulated wire cores by dowel to form simultaneously together.
Further improve, described conductor is that the 1st kind of real core conductor or the 2nd kind of stranded conductor form.
Further improve, described insulated wire cores is more than 2 or 2.
Further improve, described insulated wire cores is 2, and the global shape structure of its cable is the figure of eight.
Further improve, described insulated wire cores is 3, and the global shape structure of its cable is equilateral triangle.
Further improve, described insulated wire cores is 4, and the global shape structure of its cable is square.
Further improve, described insulated wire cores is 5, and the global shape structure of its cable is regular pentagon.
Further improve, described insulating barrier is cross-linked polyethylene insulating material or igelite Insulation Material.
Further improve, described oversheath is pvc sheath.
Further improve, described dowel adopts the igelite with the same material of oversheath.
Beneficial effect of the present invention is:
After the each insulated wire cores insulation of this cable operation finishes, do not enter stranding operation, then carry out extruding of oversheath, and while extruding oversheath with each heart yearn between dowel together extrude into entirety, such technological design, has saved about 1/4th cables manufacturing cost of labor; And because having cancelled stranding operation, therefore avoid affecting because of stranding operation defect the quality of product; Finished cable is non-circular structure, and each core insulation is closely connected with sheath; Cable is without common void filler, and construction of cable weight alleviates to some extent.To sum up, cable of the present invention has simple for structure lucid and lively, and manufacturing process is simple, and quality is convenient to control, and cost is relatively cheap, economical and practical, has certain application value.
