Abstract
A 900/75 millimeters (mm) high-strength steel reinforced aluminium conductor for plus or minus 800 Kilovolts (kV) UHV (ultra-high voltage) DC (direct-current) transmission lines is characterized in that the conductor comprises a round steel wire and a round aluminium wire, the steel wire and the aluminium wire are twisted together concentrically; the steel wire comprises seven round high-strength zincoated wires with the outside diameters of 3.69 mm; and the aluminium wire comprises eighty four round aluminium wires with the outside diameters of 3.69 mm.
Description
Technical field
The utility model relates to the used for transmission line conductor wire, relates in particular to a kind of being used for ± 900/75mm that 800kV extra-high voltage direct-current circuit electric energy transmitting is used
2The high strength steel core aluminum stranded wire.
Background technology
Along with the development of society, power 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.
Seek that more reasonable structure, intensity are higher, the better extreme high voltage of fail safe is with the built on stilts lead of using of high strength, this is one of the applicant's content of endeavouring to study always.
The utility model content
The purpose of this utility model is to provide a kind of ± 800kV extra-high voltage direct-current circuit is with 900/75 high strength lead.
It is characterized in that: whole lead is made up of by concentric manner is stranded the round aluminum steel of 7 zinc-plated round steel lines of external diameter 3.69mm high strength and 84 external diameter 3.69mm, the anti-pull-off force of whole lead is greater than 235.8kN, and the lead D.C. resistance is not more than 0.0320 Ω/km in the time of 20 ℃.
The tensile strength of the zinc-plated round steel line of external diameter 3.69mm high strength is not less than 1380MPa, and the tensile strength of the round aluminum steel of external diameter 3.69mm is not less than 160MPa, and dc resistivity is not more than 28.034n Ω .m (61.5%IACS) during 20 ℃ of aluminum steels.
The utility model provides a kind of effective solution ± 800kV extra-high voltage direct-current circuit transmission of electricity lead.
