Background technology
At home in overhead line power distribution network, substantial amounts of transformer, leader cable of transformer are used when high and low pressure voltage changes
It is the connecting line that power utilization network is incorporated into from transformer, its length is short, quantity is more.Existing leader cable of transformer uses two mostly
The aerial insulated cable of class copper conductor, the cable is harder, not flexible, is made troubles to construction and wiring;Leader cable joint
The phenomenons such as place easily occurs making moist, corrosion, cause tie point resistance to increase, influence line security operation.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of replaces with softness by the two class copper conductors used in cable
Five class soft copper conductors, be made by twisting using much smaller copper conductors, make leader cable more soft, flexible, convenient cable
The transformer flexible lead wire cable that construction and joint surely connect.
The technical problems to be solved by the invention can adopt the following technical scheme that to realize:
A kind of transformer flexible lead wire cable, including multiple conductor wire cores and the outer tube for being coated on the conductor wire core,
The multiple conductor wire core is combined into a center and is arranged on the annulus on the center periphery, in the conductor wire core
Between gap be provided with filler;
Characterized in that, the conductor wire core is the soft copper conductor of five classes, the outer tube includes being arranged on the lapping layer
The insulating barrier on periphery;The whole outer surface being piled into the multiple conductor wire core is provided with the lapping layer of consistency of thickness, described
Lapping layer surrounds the filler.
In a preferred embodiment of the invention, the outer tube also includes successively in insulating barrier outer surface circumference
The screen layer and overcoat of setting, it is Nian Jie between the insulating barrier and the screen layer, the screen layer and the overcoat it
Between be bonded.
In a preferred embodiment of the invention, the center includes at least one core conductor, and the annulus includes
At least six core conductor.
In a preferred embodiment of the invention, the center includes 1 core conductor, and the annulus includes 6
Core conductor;Tangent, ring on the inside of the outer surface of 6 core conductors in the outer surface and annulus of 1 core conductor of the center
The two neighboring core conductor in shape area is tangent;The line of the geometric center of 6 core conductors is regular hexagon, in the regular hexagon
The center superposition of the heart and 1 core conductor of the center.
In a preferred embodiment of the invention, the lapping layer is made up of nonwoven cloth material;The filler is by PP
Rope material is made;The insulating barrier is made up of elastomeric material;The screen layer is made up of high strength fibre;The overcoat is by resistance to
Heat is exempted from irradiation fire retardant insulating pvc material and is made.
As a result of technical scheme as above, the beneficial effects of the invention are as follows:
1. because " kelvin effect " of alternating current, i.e. alternating current mainly flow through from conductive surface, the surface of multi cord adds
Get up more much greater than single cord, its electric current for flowing through of same cross-sectional is bigger than single cord, and ac frequency is higher, collect skin
Effect is stronger, so the connecting line of the transformer of high frequency readily satisfies the electric current of needs using multiply flexible cord.
2.35mm2Leader cable of transformer, two class copper conductor structures be a diameter of 2.63mm of 7/2.63, i.e., 7 copper
Line is constituted;The conductor of flexible transformer leader cable is five class soft copper conductors, and structure is 276/0.385, i.e., 276 a diameter of
0.385mm strand copper wire composition;I.e.:It is made by twisting using much smaller copper conductors, makes leader cable more soft, pliable
Song, convenient cable construction and joint surely connect;Avoid joint from easily occurring making moist, the phenomenon such as corrosion, ensure circuit safe operation.
Brief description of the drawings
Fig. 1 is a kind of structural representation of transformer flexible lead wire cable of the invention.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
Referring to Fig. 1, what is provided in figure is a kind of transformer flexible lead wire cable, including multiple conductor wire cores 100 and cladding
In the outer tube 200 of conductor wire core 100, conductor wire core 100 is the soft copper conductor 110 of five classes;Using copper conductor 110 much smaller
It is made by twisting, makes leader cable more soft, flexible, convenient cable construction and joint surely connects;Avoid joint from easily occurring making moist,
The phenomenons such as corrosion, ensure circuit safe operation.Outer tube 200 is included in the whole outer surface that multiple conductor wire cores 100 are piled into
120 are provided with the lapping layer 210 of consistency of thickness, are arranged on the insulating barrier 220 on the periphery of lapping layer 210, successively outside insulating barrier 220
Surface perimeter set screen layer 230 and overcoat 240, it is Nian Jie between insulating barrier 220 and screen layer 230, screen layer 230 and prevent
It is bonded between sheath 240.
Gap between conductor wire core 100 is provided with filler 300, and filler 300 is made up of PP rope materials;It is wrapped
Layer 210 surrounds filler 300, and lapping layer 210 can be banded paper band, mica tape, alkali-free glass fibre band, non-woven fabrics, modeling
Material strip, wire cotton yarn or silk, preferably non-woven fabrics;Insulating barrier 220 can be PVC, PE, XLPE, polypropylene PP, fluoroplastics F, rubber
Glue, paper, mica tape, preferred rubber material;Screen layer 230 is made up of high strength fibre;Overcoat 240 can be PVC, PE, rubber
Glue, aluminium, steel band are preferably heat-resisting to exempt to irradiate fire retardant insulating pvc material.
Multiple conductor wire cores 100 are combined into the annulus 140 on a center 130 and the periphery of centrally disposed area 130, in
Heart district 130 includes at least one core conductor 131, and annulus 140 includes at least six core conductor 141;Preferably, center 130 is wrapped
1 core conductor 131 is included, annulus 140 includes 6 core conductors 141.The outer surface 132 of 1 core conductor 131 of center 130 with
142 tangent, the phases of two neighboring core conductor 140 of annulus 140 on the inside of the outer surface of 6 core conductors 141 in annulus 140
Cut;The line of the geometric center 143 of 6 core conductors 141 is regular hexagon 144, the center 145 of regular hexagon 144 and center
The center 133 of 130 1 core conductor 131 is overlapped.1 core conductor of 6 core conductors 141 of annulus 140 to center 130
131 form clamping force so that 1 core conductor 131 of center 130 is in close contact, between 6 core conductors 141 of annulus 140
Forming relative interaction force causes the structure of 6 core conductors 141 in annulus 140 to stablize relatively;Annulus 140 is with
