The aluminum-alloy stranded wire layer comprises an inner aluminum-alloy stranded wire layer and an outer aluminum-alloy stranded wire layer; the strengthening core is covered in the inner aluminum-alloy stranded wire layer; the outer aluminum-alloy stranded wire layer is covered outside the inner aluminum-alloy stranded wire layer; the strand direction of the inner aluminum-alloy stranded wire layer is opposite to that of the outer aluminum-alloy stranded wire layer. The high-voltage overhead conductor is characterized in that: the strengthening core is a monocoque carbon-fiber composite core with a circular cross section. The advantages of the high-voltage overhead conductor are as follows: a zinc-coated wire stranded core is replaced by the monocoque carbon-fiber composite core with the circular cross section; the production cost is low, the sag is low, the loss of electric energy is small, the weight is light, and the performance for resisting corrosion, severe cold and high-temperature is high.
Description
Technical field
The utility model belongs to high voltage overhead cable technology field, particularly relates to a kind of high voltage overhead lead of monomer-type carbon fiber complex core.
Background technology
At present, along with China's development of economic construction, people's lives and industrial production are increasing to the demand of electric power, have only continuous development and improve the power delivery network of China, can satisfy the national electricity needs that enlarges day by day.The built on stilts cable of high-tension line tower is the important component part in the power transmission system, the structure of 132KV high voltage overhead cable is followed successively by from the inside to the outside in the known technology: by the stranded strengthening core that forms of zinc-coated wire, interior aluminium alloy stranded conductor layer and outer aluminium alloy wire layer, the effect of strengthening core is the tensile strength that increases aerial cable.Above-mentioned not only have deficiencies such as sag height, weight is big, electric energy loss is big by the stranded strengthening core that forms of zinc-coated wire, and the anti-severe cold of zinc-coated wire, anticorrosive and resistance to elevated temperatures is poor, and cost is higher, thereby has increased the manufacturing cost of cable.
Summary of the invention
The utility model provides for solving the technical problem that exists in the known technology that a kind of cost is low, sag is low, electric energy loss is low, in light weight, and anticorrosive, anti-severe cold and the high high voltage overhead lead of resistance to elevated temperatures.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of high voltage overhead lead, comprise strengthening core and aluminium alloy stranded conductor layer, aluminium alloy stranded conductor layer and outer aluminium alloy stranded conductor layer in described aluminium alloy stranded conductor layer comprises, strengthening core is coated in the interior aluminium alloy stranded conductor layer, interior aluminium alloy stranded conductor layer is coated with outer aluminium alloy stranded conductor layer, the direction of lay of aluminium alloy stranded conductor layer is opposite with the direction of lay of outer aluminium alloy stranded conductor layer in described, it is characterized in that: described strengthening core is that the cross section is circular monomer-type carbon fiber complex core.
The utility model can also adopt following technical scheme:
The diameter of section of described carbon fiber complex core is 2.24mm-12.5mm.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, be coated with monomer-type in the aluminium alloy stranded conductor layer promptly and the cross section is circular strengthening core, strengthening core is a carbon fiber complex core, compare by the stranded strengthening core that forms of zinc-coated wire in this strengthening core and the known technology, has low cost of manufacture, tensile strength is big, electric energy loss is little, in light weight, sag is low, and anti-severe cold, anticorrosive and the high advantage of resistance to elevated temperatures, because the tensile strength height of cable, sag is low, characteristics such as in light weight, make the span between the shaft tower increase, highly reduce, thereby effectively reduce engineering cost.

Among the figure: 1, interior aluminium alloy stranded conductor layer; 2, outer aluminium alloy stranded conductor layer; 3, carbon fiber complex core.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of high voltage overhead lead, aluminium alloy stranded conductor layer 1 and outer aluminium alloy stranded conductor layer 2 in comprising, interior aluminium alloy stranded conductor layer 1 and outer aluminium alloy stranded conductor layer 2 are circular stranded the forming of aluminium alloy wire by the cross section, and interior aluminium alloy stranded conductor layer 1 is opposite with the direction of lay of outer aluminium alloy stranded conductor layer 2, outer aluminium alloy stranded conductor layer 2 is coated on the outer surface of interior aluminium alloy stranded conductor layer 1, be coated with monomer-type circular cross-section strengthening core in the interior aluminium alloy stranded conductor layer 1, strengthening core is that diameter of section is the carbon fiber complex core 3 of 2.24mm-12.5mm, and the conductor cross-section area is 25mm
2-1000mm
2, in the present embodiment, the diameter of section of strengthening core is 3mm, the conductor cross-section area is 100mm
2Adopting the cross section be the strengthening core of the monomer-type carbon fiber complex core 3 of circle as the high voltage overhead lead, production cost is low, tensile strength is big, electric energy loss is low, in light weight, sag is low, and anti-severe cold, anticorrosive and resistance to elevated temperatures is high.Because characteristics such as the tensile strength of cable increases, sag is low, in light weight can make the span between the shaft tower increase, and highly reduce, thereby effectively reduce engineering cost.
