Electric power overhead wire with corrosion-resistant function
Technical field
The present invention relates to a kind of electric power transmission lead, more particularly to a kind of electric power overhead wire with corrosion-resistant function.
Background technology
It is interior in recent years to focus the consruction on 1100kV UHV transmission lines according to the planning of Guo Wang Construction Company Limiteds.It is defeated Electric line construction, it is necessary to more large-section lead but to be not intended to wire diameter too big.Traverse design will consider factors, special It is not transmission capacity and economic current density, corona critical voltage, mechanical strength of wire etc..On the one hand, it is narrow in circuit Area, it is only necessary to change the wire of close section specification, need not substantially change steel tower can meet intensity and wire over the ground Requirement, but in the application with the rising of conductor temperature, its sag is necessarily increased.And original shaft tower can not possibly have very big Remaining meet the incrementss of its sag, therefore to reach that not change steel tower increase-volume 40 ~ 50% on original corridor be to have any problem 's.
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, uses in large cross line, and its corrosion resistance is significantly Strengthen, but the reduction of strength ratio steel strand wires.
The content of the invention
