Overhead conductors are used all
over the world.
After more than 100 years of continuous innovation, the technical process of overhead conductors has become more mature and standardized
.
In China, with the continuous upgrading and expansion of the power grid, the applicable voltage level of the conductor is getting higher and higher, and the requirements and standards for the design and manufacturing process of the conductor are getting higher
and higher.
Recently, Far East Cable Co.
, Ltd.
, New Far East Cable Co.
, Ltd.
, Far East Composite Technology Co.
, Ltd.
and Yixing Far East New Energy Co.
, Ltd.
, a subsidiary of Far East Smart Energy Co.
, Ltd.
(hereinafter referred to as Far East Stock Code: 600869), were jointly authorized an invention patent - "an aluminum-manganese alloy clad steel reinforced overhead conductor and preparation process thereof (ZL201911242270.
2)"
.
The authorization of this patent is another leap forward and upgrade of the technical standards of Far Eastern Conductors, which is a
milestone.
At present, there are fewer pure aluminum alloy overhead wires, and most of the overhead conductors are steel-core aluminum alloy conductors (ACSR), which have good mechanical strength while ensuring conductivity and can adapt to complex field environments
.
However, with the continuous expansion of the application range and the complexity and change of the world environment, the use environment faced by overhead conductors is also constantly changing, and many factors have caused the life of overhead conductors to be greatly reduced and safety accidents occur during use
.
As far as the failure form of the conductor itself is concerned, corrosion and disconnection are the most important cause of overhead conductor failure, accounting for nearly a quarter
of the entire overhead line accidents.
In general, the design life of overhead conductors is 30-50 years
.
However, with the development of the times and the advancement of technology, the life expectancy of overhead conductors has continued to increase
.
In coastal areas and industrial areas, the corrosion environment is complex and diverse, moisture, acidity, industrial pollutants, etc.
will cause chemical corrosion and electrochemical corrosion of the wire, and the tensile force of the corroded wire drops sharply and completely loses its use value
.
The life of overhead conductors in these areas is only 15 years or even less, and the corrosion and disconnection of overhead conductors has become a major problem
restricting the use of overhead lines.
Now the more popular anti-corrosion technology mostly uses galvanized steel core, zinc-aluminum alloy coated steel core, aluminum-clad steel core and coated anti-corrosion oil and other measures, which can enhance the corrosion resistance of the wire to a certain extent and extend the service life
.
However, the times are developing, the indicators of overhead conductors are getting higher and higher, to ensure that there will be no broken wire due to corrosion in the design life, and even improve the design life of the line, while enhancing the tensile strength of the wire, which puts forward extremely high requirements
for cable companies.
As a leader in the cable industry, Far East Horizon has developed and launched an aluminum-manganese alloy clad steel reinforced overhead conductor
.
The product reinforcement core is made of multiple aluminum-manganese alloy-clad steel single wire stranded, and the tensile strength of aluminum-manganese alloy-clad steel single wire is ≥ 1400MPa, which greatly improves the tensile strength of the wire, and other mechanical properties are also excellent
.
At the same time, the new alloy material formula greatly enhances the corrosion resistance of the alloy, and the process formula and production process have been newly optimized design, coupled with the upgrading of aluminum melt refining process and continuous casting and rolling coating process indicators, so that the life level of the product has been significantly improved
.
Innovation is the soul of an enterprise and the guarantee of
its sustainable development.
In the future, Far East will continue to adhere to the development concept of "taking innovation as the soul", continuously carry out technological innovation, and launch patented products with independent patent rights, so as to provide lasting momentum
for promoting the technological progress of the industry and leading the high-quality development of the industry.
