Abstract
The utility model relates to a cable conductor, in particular to a cable conductor with skin-effect resistance, which comprises a multi-layer cable conductor, and is characterized in that: an insulation layer is respectively wrapped at the joint between each layer of the multi-layer cable conductor. The utility model has the advantages of high section utilization rate, large current-carrying capacity, uneasy heating, low manufacture cost, and convenient manufacture process.
Description
Technical field
The utility model relates to a kind of cable conductor, especially relates to a kind of cable conductor of anti-kelvin effect.
Background technology
As everyone knows, the conductor of China 35kv and following cable all adopts and draw circle copper (aluminium) line earlier on wire drawing machine at present, carries out layer-stranding then and form on stranding machine.But the stranded conductor of this kind method is a monoblock, and when alternating current passed through conductor, because kelvin effect, flowing of electronics all concentrated on surface of conductors, makes the cross section utilance of conductor very low, little, the easy heating of its ampacity.Ampacity for the cross section that utilizes conductor to greatest extent, anti-kelvin effect, raising conductor, also the conductor of extra-high-tension cable all can be made milliken conductor: the conductor in same cross section, be spliced with five fan-shaped conductors, separate with insulating paper between piece and the piece, it is long-pending to have increased surface of conductors, makes conductor utilance height.But the manufacturing cost of this kind milliken conductor is very expensive, and manufacturing process is quite loaded down with trivial details.
Summary of the invention
The technical problem that the utility model mainly is that the cross section utilance at the existing in prior technology conductor is low, ampacity is little, easy heating, manufacturing cost costliness, manufacturing process are loaded down with trivial details etc., provide a kind of cross section utilance height, ampacity big, be not easy to generate heat, the cable conductor of cheap for manufacturing cost, anti-kelvin effect that manufacturing process is easy.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of cable conductor of anti-kelvin effect, comprise the multi-layer cable conductor, it is characterized in that junction between described each layer of multi-layer cable conductor is wrapped respectively to be provided with insulating barrier.Circle is traditional thread binding on the strand cage of stranding machine, by (1+6+12+18+24) regular stranded distribution, configure the cage speed and the hauling speed of respectively twisting cage on request, each the good back of layer strand overlapping wrapped one deck insulating paper (outermost layer does not wrap), the garden line of making is twisted into the shape of figure one.Each layer also can be made round compact conductor by pressing mould; When conductor is stranded, the characteristics that kelvin effect is arranged according to conductor, every layer of stranded good back is at its overlapping wrapped one deck insulating paper in surface, make the long-pending increase of surface of conductors, make electric current evenly pass through the whole cross section of conductor, thereby reach the ampacity of the cross section that utilizes conductor to greatest extent, anti-kelvin effect, raising conductor, the heating of minimizing conductor.
As preferably, described insulating barrier adopts the insulating paper material to make.Its production cost is cheap relatively, the space is compact, production technology is easy.
Therefore, the utlity model has cross section utilance height, ampacity big, be not easy heating, cheap for manufacturing cost, characteristics such as manufacturing process is easy.
Description of drawings
Accompanying drawing 1 is a kind of end face structure schematic diagram of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
A kind of cable conductor of anti-kelvin effect comprises the multi-layer cable conductor, and the junction between multi-layer cable conductor 1 each layer is wrapped respectively and is provided with insulating barrier 2.Insulating barrier adopts the insulating paper material to make.
When installing and using, circle is traditional thread binding on the strand cage of stranding machine, by (1+6+12+18+24) regular stranded distribution, configure the cage speed and the hauling speed of respectively twisting cage on request, each the good back of layer strand overlapping wrapped one deck insulating paper (outermost layer does not wrap), the garden line of making is twisted into the shape of figure one.Each layer also can be made round compact conductor by pressing mould; When conductor is stranded, the characteristics that kelvin effect is arranged according to conductor, every layer of stranded good back is at its overlapping wrapped one deck insulating paper in surface, make the long-pending increase of surface of conductors, make electric current evenly pass through the whole cross section of conductor, thereby reach the ampacity of the cross section that utilizes conductor to greatest extent, anti-kelvin effect, raising conductor, the heating of minimizing conductor.
Claims (2)
1. the cable conductor of an anti-kelvin effect comprises the multi-layer cable conductor, it is characterized in that junction between each layer of described multi-layer cable conductor (1) is wrapped respectively to be provided with insulating barrier (2).
2. the cable conductor of anti-kelvin effect according to claim 1 is characterized in that described insulating barrier adopts the insulating paper material to make.
