Abstract
The utility model discloses a specially-shaped aerial conductor, comprising multiple core wires which are carbon fiber-cored soft aluminum stranded conductors. The multiple core wires, i.e., the multiple carbon fiber-cored soft aluminum stranded conductors, are externally commonly wrapped with multiple transmission line layers which are formed by tightly intertwisting multiple aluminum single wires. The transmission line layers are composed of an inner layer and an outer layer. The cross section of each aluminum single wire in the inner transmission line layer is of an S type, while the cross section of each aluminum single wire in the outer transmission line layer is of a Z type. The specially-shaped aerial conductor is advantaged by being large in strength, high in conductivity, small in linear expansion coefficient, large in current-carrying capacity, light in weight, and good in usage practicability simultaneously.
Description
Technical field:
The utility model relates generally to electric power transfer lead field, mainly is a kind of special-shaped aerial condutor.
Background technology:
China's natural environment complexity is various, in order to adapt to different service conditions, the requirement of the lead that uses for China also is diversified, and China all is that to adopt the ordinary steel core aluminum stranded wire be aerial condutor all the time, the demand of situation transmission of electricity such as can not satisfy that big capacity is communicated by letter with double as.
The utility model content:
Technical problem to be solved in the utility model provides a kind of special-shaped aerial condutor, and it has, and intensity is big, conductance is high, coefficient of linear expansion is little, and ampacity is big, and quality is light simultaneously, uses Practical Performance good.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of special-shaped aerial condutor, include many heart yearns, it is characterized in that: described heart yearn refers to the soft aluminium stranded conductor of carbon fiber core, and the heart yearn of the described many soft aluminium stranded conductors of carbon fiber core is enclosed with the multilayer transmission line layer outward jointly, and described transmission line layer is by some single line aluminium tight stranded compositions; Described transmission line layer has inside and outside two-layer, and the single line aluminium cross section in the described internal layer transmission line is the S type, and the single line aluminium cross section in the outer transmission line is the Z type.
The heart yearn of the soft aluminium stranded conductor of described carbon fiber core is to coat the single plug of making by layer and glass fibre centered by the carbon fiber.
The version of the utility model lead is comparatively innovated; it not only is conducive to improve rectilinear tubes; the crimp strength of strain clamp and lead; and because the outer surface of heart yearn is the glass layer of insulator; thereby do not have contact potential difference between the transmission line layer of itself and outer field aluminum steel, can protect aluminium conductor to avoid galvano-cautery.
The utility model is compared with circular section aluminum steel thigh aerial condutor has more compact structure, and the actual effective cross-section of profiled-cross-section aluminium alloy wire thigh aerial condutor can reach about 95%, and circular section aluminum steel thigh aerial condutor can only reach 78%.Under the identical situation of diameter, special-shaped cutting has bigger aluminium sectional area.Ampacity can be improved greatly, and line loss can be reduced; This compact structure smooth surface has improved the surface roughness coefficient of lead greatly, is conducive to improve the corona inception voltage of lead, can also reduce the level of corona noise and radio interference.Can take precautions against wire icing, thereby deadweight increases the design load of the tower bar cause the whole piece circuit to surpass transmission line, prevent that effectively the tower line that collapses from ruining, accidents such as electrical network paralysis are strengthened power grid security.
Described single line aluminium is twisted into circular shaped conductors closely through special stranded equipment and extraordinary production technology, makes in its lead closely seamless between the monofilament.
The utility model has the advantages that:
This practicality has newly that intensity is big, conductance is high, coefficient of linear expansion is little, and ampacity is big, and quality is light simultaneously, uses Practical Performance good.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to accompanying drawing 1, a kind of special-shaped aerial condutor, include many heart yearns 1, described heart yearn 1 refers to the soft aluminium stranded conductor of carbon fiber core, the outer multilayer transmission line layer 2 that is enclosed with jointly of the heart yearn 1 of the described many soft aluminium stranded conductors of carbon fiber core, described transmission line layer 2 is by 3 tight stranded compositions of some single line aluminium; Described transmission line layer 2 has inside and outside two-layer, and single line aluminium 3 cross sections in the internal layer transmission line are the S type, and single line aluminium 4 cross sections in the outer transmission line are the Z type.
The heart yearn 1 of the soft aluminium stranded conductor of described carbon fiber core is to coat the single plug of making by layer and glass fibre centered by the carbon fiber.
