Description
Technical field
The utility model belongs to cable machinery technical field, and in particular to a kind of high strength steel core aluminum stranded wire.
Background technology
In transmission line of electricity, the cable being commonly used is steel-cored aluminium strand, stranded wire in existing steel-cored aluminium strand
Round wires structure is, is linear contact lay between wire, contact area is small, causes the current-carrying capacity of wire small.Meanwhile, have between circle aluminum steel
Larger space, easily allows moisture to invade corrosion, especially in the region having a humid climate, electrochemistry can occur between steel core and aluminum steel
Corrosion, easily causes aluminum steel to be broken.
Additionally, the tensile capacity of common steel-cored aluminium strand is not strong, ant wind load and ice load ability, especially more extreme
Weather in, such as extremely cold or very hot weather, steel-cored aluminium strand is easily affected, and exceedingly odious weather is just electricity consumption
Peak period, the use of a large amount of air-conditionings, heating equipment and refrigeration plant is easily caused electricity shortage.
The content of the invention
The purpose of this utility model is to provide a kind of high strength steel core aluminum stranded wire of tensile anticorrosion.
For achieving the above object, the technical scheme that the utility model is used is：A kind of high strength steel core aluminum stranded wire,
Including high-strength steel core and multilayer aluminum conductor layer, the aluminum conductor layer is coated on outside high-strength steel core, and is twisted by many aluminum conductors
Conjunction is crushed to, and the cross section of the aluminum conductor is the aluminum conductor direction of lay phase in Z-type or S types, and adjacent two layers aluminium conductor
Instead；Anti-corrosion packed layer is provided between the high-strength steel core and aluminum conductor layer；The aluminum conductor layer outside is coated with insulation successively
Layer, elastic packed layer and water-proof jacket layer, are provided with multiple springs in the elastic packed layer, one end of the spring is connected in insulation
Layer outside, the other end is connected in water-proof jacket layer inner side, light filling elastomeric material between multiple springs；The water-proof jacket layer is outer
Scribble slip agent.
Preferably：Described aluminum conductor layer is set to three layers, the aluminum conductor number of each layer be followed successively by from inside to outside 10,16
Root, 24.
Preferably：Described number springs are 8.
Preferably：Described light elastic material is TPE.
The utility model has the advantages that：Steel core and aluminum stranded conductor close structure, tensile strength are big, windproof can subtract
Shake, reduces the influence of accumulated snow rainwater weather.Specifically, the utility model sets between the water-proof jacket in steel-cored aluminium strand and outside
The elastic layer of spring is equipped with, the effect of damping can be played, when strong wind weather is run into, cable is subject to the involve power of wind, elasticity
Layer can play cushioning effect, and because the active force of both ends of the spring is identical, but the quality of water-proof jacket is twisted much smaller than steel-core-aluminium
Line, therefore water-proof jacket shakes relative to steel-cored aluminium strand under spring and wind action power, it is possible to reduce wind is to cable
Traction action power.Meanwhile, in sleety weather, snow-broth is dropped on water-proof jacket, and water-proof jacket is provided by snow-broth and spring
, there is trembling for small range in the influence of double reaction plus, so not only reduce impulsive force of the sleet to cable, and can accelerate
The drippage of sleet, mitigates cable and bears a heavy burden.The outermost slip agent of water-proof jacket also accelerates sleet drippage.
Additionally, being squeezed into Z-type or S types by many aluminum stranded conductors are stranded, the contact area between aluminum steel is increased, between reducing aluminum steel
Gap, discharges between can so reducing aluminum steel, reduces consumption of the electric energy in course of conveying.And in high-strength steel core and aluminum stranded conductor
Between fill anti-corrosion material, steel-cored aluminium strand can be avoided to be corroded, can use various environment, strengthen it and use the longevity
Life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is another structural representation of the present utility model.
Specific embodiment
A kind of high strength steel core aluminum stranded wire as shown in Figure 1, 2, including high-strength steel core 1 and multilayer aluminum conductor layer 3, it is described
Aluminum conductor layer 3 is coated on outside high-strength steel core 1, and is crushed to by many aluminum conductors are stranded, and the cross section of the aluminum conductor is Z
Aluminum conductor direction of lay in type or S types, and adjacent two layers aluminium conductor is opposite.Z-type and S types are squeezed into by many aluminum conductors are stranded
So that the utility model structure is even closer, its tensile strength is further enhancing, and reduced aluminum conductor gap, reduce aluminium
Electric discharge between wire, so effectively reduces consumption of the electric power in course of conveying.
Further, described aluminum conductor layer 3 is set to three layers, the aluminum conductor number of each layer be followed successively by from inside to outside 10,
16,24.The direction of lay of adjacent two layers aluminum conductor layer 3 is conversely, aluminum conductor layer 3 can be innermost layer S as shown in Figure 1
Type, middle Z-type, outermost layer S types, or innermost layer Z-type as shown in Figure 2, middle S types, outermost layer Z-type.
To strengthen its antiseptic property, extend its service life, be provided with anti-between the high-strength steel core 1 and aluminum conductor layer 3
Rotten packed layer 2, reduces the corrosion of steel core and aluminium conductor.The outside of the aluminum conductor layer 3 is coated with insulating barrier 4, elasticity filling successively
Layer 5 and water-proof jacket layer 6, are provided with multiple springs in the elastic packed layer 5, one end of the spring is connected in the outside of insulating barrier 4,
The other end is connected in the inner side of water-proof jacket layer 6, light filling elastomeric material between multiple springs.The number of the spring can be as
8 shown in Fig. 1, it is also possible to set less or more, be advisable with 4~16, number springs it is very few so that aluminum conductor layer 3 with it is anti-
Discontinuity equalization between water restrictive coating 6, is easily damaged spring, or even causes shadow to the structure of high-strength steel core 2 and aluminum conductor layer 3
Ring；Number springs are excessive to make water-proof jacket layer 6 excessively balance again, it is difficult to reduce stress by trembling and accelerate sleet to slide.
The light elastic material filled between spring can be General Purpose Rubber, or it is preferred that described light elastic material is TPE,
TPE has high resiliency, high intensity, can play good cushioning effect.In order to reduce during the stop on the utility model such as sleet
Between, reduce cable load, slip agent is scribbled outside the water-proof jacket layer 6, sleet can be accelerated to slide.
