Abstract
The utility model provides a half round conductor power cable which the structure is: two the same conductors, every conductor radial cross section is semicircle - shaped, half and half round conductor wraps up the insulating layer outward, the transposition of two conductors constitutes radial cross section and is the circular shape cable core, the first band that winds of the outer cladding of cable core, it has the stopping closely to pack in the cable core, wrap up inner sheath, the outer armor metallic braid of inner sheath outward around the band, the cladding second is around the band, at this cladding oversheath outside the band layer outside the metallic braid. Compared with the prior art, the conductor material is saved to this structure cable under the same function and performance requirement, more electric, machinery of the performance of cable and thermal behavior etc. Are more excellent simultaneously.
Description
Technical field
The technical program belongs to cable technology field, specifically a kind of half round conductor power cable.
Background technology
One of critical specifications of cable is that conductor radial section is long-pending, in general identical material lower conductor radial sectionLong-pending larger its resistance is less. Under general thinking, the consumption of the larger and conductor material of sectional area is larger, cableExternal diameter is also larger, and how to solve this contradiction, is cable industry engineers and technicians, or even conductor materialThe difficult problem that researcher faces.
Summary of the invention
In order to solve the described problem existing in prior art, the invention proposes a kind of half new round conductor electricityPower cable, specific as follows:
A kind of half round conductor power cable, its structure is:
Two same conductor, every conductor radial section is semi-circular shape; Half and half round conductor outer wrapping insulating barrier;The stranded formation radial section of two conductors is circular cable core; Cable core outer cladding the first twining package tape is tight in cable coreBe filled with inserts; Twining package tape outer wrapping inner sheath, the armoured wire sheathing of inner sheath; At wire sheathingOuter cladding the second twining package tape, at this wrapped belt outer cladding oversheath.
The conductor of described semi-circular shape, its width: be highly (9.8～10.3): (4.8～5.2); Insulating barrier isCrosslinked polyetylene insulated layer.
Described conductor forms by monofilament is stranded, and the monofilament direction of lay in two conductors is identical, two conductors strandedDirection is contrary with monofilament direction of lay; The lapping direction of the first twining package tape is contrary with the direction of lay of two conductors.
Inserts is polypropylene tearing fiber (being PP rope), and its specification is without particular/special requirement.
The material of first and second twining package tape is all nonwoven; This nonwoven nominal requires as 0.2mm; The first,It is 15% that the mean value of the rate of putting up of two layers of twining package tape is all not less than.
Described inner sheath is cross-linked polrvinyl chloride; Described oversheath is termite-proof cross-linked polrvinyl chloride.
Wire sheathing is that zinc-coated wire and zinc-plated hard copper silk evenly mix dress armour formation; Zinc-coated wire and zinc-plated hardThe usage ratio of copper wire is 4:1～6:1;
The diameter of zinc-coated wire and zinc-plated hard copper silk is all 1.6mm.
For example: adopt the II group zinc-coated wire of 30 ± 2 nominal diameter 1.6mm, 6 nominal diameter 1.6mmZinc-plated hard copper silk carry out armouring.
Compared with prior art, this structural cable, under identical function and performance requirement, is saved conductor material, withTime more electric, the machinery of performance of cable and hot property etc. more excellent.
Amass as 35mm taking conductor radial section2Copper core cable is example, and the key technical indexes is as following table 1:

Detailed description of the invention
The technical program is further illustrated as follows below in conjunction with accompanying drawing and detailed description of the invention:
As Fig. 1, a kind of half round conductor power cable, its structure is: two same conductor, every conductor is radiallyCross section is semi-circular shape; Half and half round conductor outer wrapping insulating barrier; The stranded formation radial section of two conductors is circularCable core; Cable core outer cladding the first twining package tape, is closely filled with inserts in cable core; In twining package tape outer wrapping, protectCover, the armoured wire sheathing of inner sheath; At wire sheathing outer cladding the second twining package tape, at this wrapped beltOuter cladding oversheath.
The conductor of described semi-circular shape, its width: be highly (9.8～10.3): (4.8～5.2); Insulating barrier isCrosslinked polyetylene insulated layer.
Described conductor forms by monofilament is stranded, and the monofilament direction of lay in two conductors is identical, two conductors strandedDirection is contrary with monofilament direction of lay; The lapping direction of the first twining package tape is contrary with the direction of lay of two conductors.
Inserts is polypropylene tearing fiber (being PP rope), and its specification is without particular/special requirement.
The material of first and second twining package tape is all nonwoven; This nonwoven nominal requires as 0.2mm; The first,It is 15% that the mean value of the rate of putting up of two layers of twining package tape is all not less than.
Described inner sheath is cross-linked polrvinyl chloride; Described oversheath is termite-proof cross-linked polrvinyl chloride.
Wire sheathing is that zinc-coated wire and zinc-plated hard copper silk evenly mix dress armour formation; Zinc-coated wire and zinc-plated hardThe usage ratio of copper wire is 4:1～6:1.
In this example, adopt the II group zinc-coated wire of 30 ± 2 nominal diameter 1.6mm, 6 nominal diameter 1.6mmZinc-plated hard copper silk carry out armouring.
