Description
Technical field
The present invention relates to a kind of electric power transmission lead, more particularly to a kind of resistant slide electric power overhead aluminum stranded conductor.
Background technology
The continuous rapid growth of Chinese national economy is being continuously increased to the demand of electric power, according to Guo Wang Construction Company Limiteds
Planning, it is interior in recent years to focus the consruction on 1100kV UHV transmission lines.Transmission line construction, it is necessary to more large-section lead but
It is too big that wire diameter is not intended to again.Traverse design will consider that the transmission capacity and economic current of factors, particularly wire are close
Degree, corona critical voltage, mechanical strength etc..On the one hand, in the narrow area of circuit, it is only necessary to change leading for close section specification
Line, need not substantially change steel tower can meet the requirement of intensity and wire over the ground, but in the application with conductor temperature
Rising, its sag necessarily increases.And original shaft tower can not possibly have very big remaining to meet the incrementss of its sag, therefore will
Reach that not changing steel tower increase-volume 40 ~ 50% on original corridor has any problem.
On the other hand, existing aluminum conductor uses galvanized strand wires as stress unit, and this structure has been used more than 100 years,
It is traditional structure.But galvanized strand wires intensity is not high, and corrosion resistance is not strong, wire whole service life is shortened.The eighties, go out
Xian Lv Baogangs single line, at that time because of complex process, it is difficult to promote, now, is used, its corrosion resistance is significantly in large cross line
Strengthen, but strength ratio steel strand wires are reduced.
The content of the invention
The present invention provides a kind of resistant slide electric power overhead aluminum stranded conductor, and resistant slide electric power overhead aluminum stranded conductor both ensure that in aluminium lamination
