Description
Technical field
The utility model belongs to field of electrical equipment, and in particular to the improvement of aerial cable construction and arrangement.
Background technology
Cable is mainly made up of following 4 part.First, conductor thread core：Use high conductivity material（Copper or aluminium）It is made.According to deposited
If requirement of the use condition to cable softness, the every line heart may be formed by solid conductor or multiple conducting wires are stranded.2nd, absolutely
Edge layer：Insulating materials as cable should have an insulaion resistance high, breakdown field strength high, low dielectric loss and low
Dielectric constant.The insulating materials commonly used in cable has oil-paper, polyvinyl chloride, polyethylene, crosslinked polyethylene, rubber etc..Electricity
Cable is often classified with insulating materials, such as oil-impregnated paper insulation cable, polyvinyl chloride cable, twisted polyethylene cable etc..3rd, sealing shield
Set：Protection insulated wire heart is protected from the damage of machinery, moisture, moisture, chemical substance, light etc..For the insulation of moisture-sensitive, typically adopt
With lead or aluminium extrusion sealing sheath.
In aerial cable, because the need for engineering, aerial cable needs bigger tensile strength, one compared to general cable
As aerial cable in order to reduce financial cost, obtain bigger tensile strength and bending strength, can be made using steel-cored aluminium strand
Into the conductor thread core in cable.
The content of the invention
The purpose of this utility model is to provide that a kind of tensile strength is big, more preferable aerial cable.
For achieving the above object, the technical scheme that the utility model is used is：A kind of tensile strength is big to make somebody a mere figurehead
Cable, including restrictive coating and the cable core by restrictive coating parcel, the cable core include that cross section is the nylon66 fiber material of hub-like
Inner support；The inner support includes middle part and six support plates to ambient radiation, and the support plate one end is connected with the middle part, described
Inner support also includes outside plate, and the other end of the adjacent support plate is connected by outside plate；The shape that six support plates are constituted with outside plate
The cross section outline of shape is regular hexagon；The middle part is provided with central passage, and the support plate is internally provided with week along passage,
This week is close to the other end of the support plate along passage；Steel-core-aluminium magnesium alloy strand, six branch are provided with the central passage
It is provided with gap between plate and along passage almag twisted wire in the week.
Preferably：The week is connected between the almag twisted wire in passage by copper mesh screen layer, the copper mesh screen
Cover layer and the week is wrapped up along the almag twisted wire in passage.
Preferably：Copper strip shielding layer is provided between described cable core and restrictive coating.
Preferably：Be provided with insulation liner layer between copper strip shielding layer and the cable core, the insulation liner layer with
Almag rope is evenly equipped with packed layer between the cable core.
Preferably：Three almag ropes are set between the outside plate and insulation liner layer.
The utility model has the advantages that：By the inner support described in setting, its outline section is set to
Regular hexagon, almag twisted wire is arranged in the hexagonal of the regular hexagon, compared to circle, when cable is tension or in compression
When, power can be more evenly spread to while on the almag twisted wire, twist the more almags high to intensity of power
Line is concentrated, and makes the inner support more durable, and also part almag twisted wire is evenly distributed in inside the inner support, and because
It is not only lightweight for inner support employs the big flexible material of tensile strength as nylon66 fiber, and with almag twisted wire
Such twisted wire merging higher compared to steel quality lighter, intensity is used, and is increased under the little situation of the relative lifting of quality
The big cross section of cable, so significantly improves the tensile strength of cable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
It is as shown in Figure 1, a kind of big aerial cable of tensile strength, including restrictive coating 1 and the cable that is wrapped up by restrictive coating 1
Core, the cable core includes that cross section is the inner support 2 of hub-like；The inner support 2 includes middle part 2a and to ambient radiation six
Individual support plate 2b, support plate 2b one end is connected with the middle part 2a, and the inner support 2 also includes outside plate 2c, the adjacent support plate 2b
The other end connected by outside plate 2c；The cross section outline of the shape that six support plate 2b and outside plate 2c is constituted is positive six side
Shape；The middle part 2a is provided with central passage 3, and the support plate 2b is internally provided with week along passage 4, and this week is close to along passage 4 should
The other end of support plate 2b；Steel-core-aluminium magnesium alloy strand 5 is provided with the central passage 3, between six support plate 2b between
In gap 6 almag twisted wire 7 is provided with the week along passage 4 is interior；The inner support 2 is made using nylon66 fiber.Central passage 3
It is in gap 6 between interior twisted wire cross-sectional area and six support plate 2b and described all along the almag twisted wire 7 in passage 4
Cross-sectional area sum can be with identical, it is also possible to less than in the gap 6 between six support plate 2b and described all along passage 4
The cross-sectional area sum of almag twisted wire 7.
The outline section of the inner support 2 is set to regular hexagon, almag twisted wire 7 is arranged on the regular hexagon
Hexagonal on, compared to circle, when cable is tension or in compression, power can be more evenly spread on the almag twisted wire 7
While, power is more concentrated to intensity almag twisted wire 7 high, make the inner support 2 more durable.Inner support 2 is adopted
It is not only lightweight with the big flexible material of tensile strength as nylon66 fiber, and compared with almag twisted wire 7 is such
Merge in steel quality lighter, intensity twisted wire higher and use, cable is increased under the little situation of the relative lifting of quality
Cross section, so significantly improves the tensile strength of cable.
The week is connected between the almag twisted wire 7 in passage 4 by copper mesh screen layer 8, the copper mesh screen layer 8
And the week is wrapped up along the almag twisted wire 7 in passage 4.
Here copper mesh screen layer 8 can not only play a part of inner shield, may also operate as strengthening all along passage 4
The effect of the stability of almag twisted wire 7, makes week relatively reliable along the almag twisted wire 7 in passage 4.
Copper strip shielding layer 9 is provided between described cable core and restrictive coating 1.External shielding layer is so set, reinforcing cable
Shielding properties.
