Description

A kind of microlight-type transmission of electricity wire
Technical field
The utility model relates to the electric wire field, specifically refers to a kind of microlight-type transmission of electricity wire.
Background technology
The final energy form that electric energy comes as various energy conversions is served human society, becomes requisite production, factor in living in the human lives.Electric energy is produced by electric energy such as hydroelectric station, thermal power station, wind fields usually with producing, wants to take full advantage of electric energy and electric power must be sent to endlessly to electricity needs ground.The mankind enter the information age, day by day serious to the dependence of electric power, are not singly that large scale industry needs a large amount of electric power, the work-at-home electric consumption on lighting, and various communication apparatus electricity consumptions, carrying mankind bulk information equipment be unable to do without electric energy too.Thereby supply of electric power need to guarantee that clog-free stable transfer meets the human society needs.
Along with social development, the electrical transmission technology is constantly progressive, and transmission voltage improves constantly, and transmission of electricity length is more and more longer, and transmission of electricity, by the past form of communication, develops into interchange, direct current and deposits.As the aerial condutor of electric energy transmitting also development, its security requirement is more and more higher.
The wire of the existing electric line used, by a copper wire, at center, its outside is surrounded by insulating barrier, and for ampacity large wire, conductor is to be combined and increased the flow of electric current by the strand copper wire coil buckling.The shortcoming of this wire is: can not bring into play the flow in maximum unit cross section, because electric current is all easily to flow through from the outer surface of conductor, the central part flow is very little, and the structure of this kind of wire has not only strengthened resistance and also wasted a large amount of materials.
The utility model content
Technical problem to be solved in the utility model is to provide that a kind of more reasonable structure, manufacturing process are simple, low price, tensile strength is good, resistivity is little, long service life, microlight-type transmission of electricity wire that security performance is high.
Wire is used in a kind of microlight-type transmission of electricity described in the utility model, comprises high strength galvanized steel bar sandwich layer and circle aluminum-wire layer, and this wire is that the round aluminum-wire layer outer with being coated on high strength galvanized steel bar sandwich layer by high strength galvanized steel bar sandwich layer forms by concentric manner is stranded.
Further improve, described high strength galvanized steel bar sandwich layer is divided into three layers and adopt that concentric manner is stranded to be formed by 19 high strength galvanized steel bar lines, and the quantity of high strength galvanized steel bar line is 1,6 and 12 from inside to outside.
Further improve, described round aluminum-wire layer is divided into four layers and adopt that concentric manner is stranded to be formed by 88 round aluminum steels, and the quantity of justifying from inside to outside aluminum steel is 13,19,25 and 31.
Further improve, the external diameter of described high strength galvanized steel bar line is 3.00mm again; The external diameter of described round aluminum steel is 4.50mm.
The beneficial effects of the utility model are:
Wire described in the utility model is comprised of by concentric manner is stranded the round aluminum steel of 19 external diameter 3.00mm high strength galvanized steel bar lines and 88 external diameter 4.50mm, make the anti-pull-off force of whole wire be greater than 358.84kN, in the time of 20 ℃, the wire D.C. resistance is not more than 0.01966 Ω/km, compared with prior art, tensile strength, the resistivity of wire have been improved, also improve ampacity, thereby made the security performance of wire obtain guarantee, improved the useful life of wire.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of microlight-type transmission of electricity wire described in the utility model, comprise high strength galvanized steel bar sandwich layer 1 and circle aluminum-wire layer 2, this wire is that the round aluminum-wire layer 2 outer with being coated on high strength galvanized steel bar sandwich layer 1 by high strength galvanized steel bar sandwich layer 1 forms by concentric manner is stranded; The anti-pull-off force of whole wire is greater than 358.84kN, and in the time of 20 ℃, the wire D.C. resistance is not more than 0.01966 Ω/km.The high strength galvanized steel bar line 3 that described high strength galvanized steel bar sandwich layer 1 is 3.00mm by 19 external diameters is divided into three layers and adopt that concentric manner is stranded to be formed, and the quantity of high strength galvanized steel bar line 3 is 1,6 and 12 from inside to outside; Circle aluminum-wire layer 2 is that 4.50mm circle aluminum steel 4 is divided into four layers and adopt that concentric manner is stranded to be formed by 88 external diameters, and the quantity of round aluminum steel 4 is 13,19,25 and 31 from inside to outside.The tensile strength of described high strength galvanized steel bar line 3 is not less than 1380MPa, and the tensile strength of circle aluminum steel 2 is not less than 160Mpa, and during 420 ℃ of aluminum steels of circle, DC resistivity is not more than 28.034n Ω .m(61.5%IACS).
The concrete application approach of the utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
