Background technology
The lead that uses on the existing built on stilts power transmission and transformation line is common zinc-coated wire and the common aluminum alloy single line is stranded forms; The transmission capacity of this ordinary steel core aluminum conductor is little, and the long-term work temperature has only 70 ℃, and coefficient of linear expansion is big, and sag is big.How growing along with the continuous development of building cause and need for electricity solves electric power and carries bottleneck, for building cause provides abundant electric power resource, has become the current key issue that presses for solution.
Summary of the invention
The objective of the invention is to overcome disadvantages of background technology, a kind of improvement of power transmission and transformation lead is provided, this lead should have the characteristics of big ampacity, high heat resisting temperature, high pull-off force, and when operation sag little, long service life.
Another object of the present invention provides a kind of manufacturing process of superalloy, and the aluminium alloy of this explained hereafter should have higher heat resistance, and can the supporting superalloy conductor that is used for.
The technical solution used in the present invention is:
High-intensity clearance ultra heat resisting aluminum alloy lead, comprise stranded steel core that forms of high-tensile steel wires and the stranded superalloy single line that is coated on the steel core periphery, described steel core surface is twined by arcuate line and is coated the then stranded outer surface that is coated on arcuate line of aluminium alloy single line; Have the gap between steel core and the arcuate line, be filled with anticorrosion heat-resisting ointment in the gap.
Described arcuate line is the superalloy line.
The ointment layer thickness that described anticorrosion heat-resisting ointment forms is 0.3～1.2mm.
The manufacturing process of described high-intensity clearance ultra heat resisting aluminum alloy lead, carry out according to the following steps:
A, system superalloy single line:
1) aluminium is fully dissolved;
2) element of following composition of adding and weight portion thereof:
Zr?0.15～0.29％
Fe?0.10～0.20％
Si?0.05～0.15％
B 0.05～0.10％
Also comprise micro-C, Mn, Cr, V, Ti, Cu;
3) through after refining, the degasification operation, be rolled into the aluminium bar;
4) the aluminium bar is drawn into the superalloy single line through (350～420) ℃, (80～120) h Ageing Treatment.
B, high strength steel skein silk are made steel core;
C, strand system superalloy conductor:
Carrying out following operation on the frame type stranding machine: on steel core, be coated with earlier the anticorrosion heat-resisting ointment of last layer, then several arcuate line that will be rolled at the steel core outer circumference surface earlier are spliced into the coating layer in an annular cross section, keep suitable gap between coating layer and the steel core, to hold described anticorrosion heat-resisting ointment; Superalloy single line more than outer circumference surface coiling one deck of coating layer then.
The thickness of described anticorrosion heat-resisting ointment is 0.3-1.2mm.
The invention has the beneficial effects as follows:
1) heat resistance owing to the superalloy that the present invention obtained is significantly improved, its long-term work temperature reaches more than 210 ℃ after making lead, transmission capacity increases 1 times, (and 70 ℃ of the conductor long-term work temperature of ordinary steel core aluminum conductor that strength retention is more than 90%, transmission capacity only is half of this lead), also obviously prolong useful life.
2) the carrying steel core of this lead adopts special high-strength zinc-coated wire, intensity 180kgf/mm
2More than, in lead when operation, born whole load (and steel core intensity 120kgf/mm of ordinary steel core aluminum conductor by steel core
2, steel core and the common bearing load of conductor part during the lead operation).
3) inner conductor of this lead adopts bow type structure, guarantees to exist between conductor and the steel core gap (and the inner conductor of ordinary steel core aluminum conductor adopts round structure), thereby can hold anticorrosion heat-resisting ointment effectively, has obvious effect for reducing sag.
4) there is the gap between superalloy conductor and steel core, fills anticorrosion heat-resisting ointment in the gap; Steel core is born wire tension separately, when more than the stringing temperature, moving, the comprehensive coefficient of linear expansion of lead is exactly the coefficient of linear expansion of high-tensile steel wires, sag is little (very close to each other between the conductor of ordinary steel core aluminum conductor and steel core during the lead operation, the comprehensive coefficient of linear expansion of lead is determined jointly by the steel core and the conductor lines coefficient of expansion, comprehensive coefficient of linear expansion is big, so sag is big).
