Description

UHV transmission line aluminium alloy stranded conductor
Technical field
The present invention relates to a kind of electric power transmission lead, more particularly to a kind of UHV transmission line aluminium alloy 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 of factors, particularly wire and economic current 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 and do not change steel tower increase-volume 40 ~ 50% on original corridor and have any problem.
On the other hand, existing aluminum conductor uses galvanized strand wires this structure has used more than 100 years as stress unit, 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, used in large cross line, its corrosion resistance is significantly Strengthen, but intensity reduces than steel strand wires.
The content of the invention
The present invention provides a kind of UHV transmission line aluminium alloy stranded conductor, this UHV transmission line aluminium alloy stranded conductor Structure both ensure that some carbon fibre precursor roundings in aluminium lamination, it also avoid the damage of follow-up aluminium lamination in use, so as to The reliability of electrical property is ensure that, polyester gluing filler bonding force is strong, is formd between some carbon fibre precursors seamless Sealing structure, there is well heat-resisting, cold resistance, the corrosion of acid and alkali-resistance salt medium and heat endurance, stationarity is good, anti-slipping property By force.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of UHV transmission line aluminium alloy stranded conductor, It is twisted including the stress unit positioned at center and successively the first aluminium alloy conductive layer, the second aluminium alloy in stress unit outer surface Conductive layer；
The first aluminium alloy conductive layer is twisted by 10 ~ 14 first aluminium single lines, the second aluminium alloy conductive layer It is twisted by 16 ~ 20 second aluminium single lines；
The second aluminium alloy conductive layer outer surface is twisted successively aluminium conductor clad, and aluminium conductor clad is by 19 ~ 21 Root section is twisted for " Z " font aluminium alloy conductor of " Z " font；
The stress unit includes being located at the first carbon fiber single line at center and is twisted in the first carbon fiber single line outer surface 6 Root the second carbon fiber single line, the first carbon fiber single line and the second carbon fiber single line outer surface are coated with aluminium lamination, the aluminium The thickness of layer is 0.1 ~ 0.4mm；
The first carbon fiber single line, the second carbon fiber single line are twisted by some carbon fibre precursors；Positioned at aluminium lamination It is interior and polyester gluing filling part is filled between some carbon fibre precursors；
The polyester gluing filling part is by the first component and the second component according to 1：2 ~ 4 mass ratio mixes, described First component is made up of the raw material of following weight parts：100 parts of N-307 unsaturated polyester (UP)s, 18 parts of butyl acrylate, acrylic acid are different 26 parts of monooctyl ester, 10 parts of n-butanol, 8.5 parts of toluene, 1.5 parts of talcum powder, 3 parts of aluminium powder, 10 parts of calcium carbonate, 0.8 part of triethylene tetramine；
Second component is made up of the component of following parts by weight：
100 parts of acrylic acid,
