Abstract
The invention discloses an ultra-light power transmission lead, which comprises a high-strength zinc-plated round steel core layer and a circular aluminum wire layer, and is formed by concentrically twisting the high-strength zinc-plated round steel core layer and the circular aluminum wire layer coated outside the high-strength zinc-plated round steel core layer, wherein the high-strength zinc-plated round steel core layer 1 is formed by concentrically twisting 19 high-strength zinc-plated round-steel wires 3 of which the outer diameters are 3.00 millimeters in three layers; one, six and twelve high-strength zinc-plated round steel wires 3 are arranged from inside to outside; the circular aluminum wire layer 2 is formed by concentrically twisting 88 round aluminum wires of which the outer diameters are 4.50 millimeters in four layers; and thirteen, nineteen, twenty-five and thirty-one round aluminum wires are arranged from inside to outside. The ultra-light power transmission lead has the advantages of simple manufacturing process, low price, high tensile strength, low resistance, long service life, high safety performance and the like.
Description
Technical field
The present invention relates to the electric wire field, specifically refer to a kind of microlight-type transmission of electricity lead.
Background technology
Electric energy is served human society as the final energy form that the various energy are transformed, and becomes requisite production, factor in living among 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 electricity needs ground.The mankind enter the information age, and are serious day by day to the dependence of electric power, singly are not 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 are carried human bulk information equipment and are be unable to do without electric energy too.Thereby supply of electric power need guarantee that clog-free stable transfer satisfies the human society needs.
Along with the development of society, 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 is by the past form of communication, develops into interchange, direct current and deposits.As the also constantly development of aerial condutor of electric energy transmitting, its security requirement is more and more higher.
The lead of existing employed electric line, at the center, its outside is surrounded by insulating barrier by a copper wire, and for the big lead of ampacity, and conductor is to be combined and increased the flow of electric current by the coil buckling of multiply copper cash.The shortcoming of this lead is: can not bring into play the flow in maximum unit cross section, flow through because electric current all is easy outer surface from conductor, the central part flow is very little, and the structure of this kind lead has not only strengthened resistance and also wasted wide variety of materials.
Summary of the invention
Technical problem to be solved by this invention provides 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 lead that security performance is high.
Lead is used in a kind of microlight-type transmission of electricity of the present invention, comprises the zinc-plated round steel sandwich layer of high strength and circle aluminum steel layer, and this lead is to be formed by concentric manner is stranded by the zinc-plated round steel sandwich layer of the high strength round aluminum steel layer outer with being coated on the zinc-plated round steel sandwich layer of high strength.
Further improve, the zinc-plated round steel sandwich layer of described high strength is divided into three layers and adopt that concentric manner is stranded to form by 19 zinc-plated round steel lines of high strength, and the quantity of the zinc-plated round steel line of high strength is 1,6 and 12 from inside to outside.
Further improve, described round aluminum steel layer is divided into four layers and adopt that concentric manner is stranded to form by 88 round aluminum steels, and the quantity of justifying aluminum steel from inside to outside is 13,19,25 and 31.
Further improve, the external diameter of the zinc-plated round steel line of described high strength is 3.00mm again; The external diameter of described round aluminum steel is 4.50mm.
Beneficial effect of the present invention is:
Lead of the present invention is made up of by concentric manner is stranded the round aluminum steel of 19 zinc-plated round steel lines of external diameter 3.00mm high strength and 88 external diameter 4.50mm, make the anti-pull-off force of whole lead greater than 358.84kN, the lead D.C. resistance is not more than 0.01966 Ω/km in the time of 20 ℃, compared with prior art, tensile strength, the resistivity of lead have been improved, also improve ampacity, thereby made the security performance of lead obtain guarantee, improved the useful life of lead.
