This is where grid investment will focus in the next decade

Recently, there has been frequent good news in the UHV field:

Baihetan sent Jiangsu UHV project to the whole line

Jinshang-Hubei ± 800 kV UHV accelerated

Fujian Nortel South Transmission UHV (Yongchun Section) started

.
.

.

With the acceleration of the construction of new energy bases

The need and challenge of balancing power space is increasing

As the main means to solve the problem of new energy consumption

UHV construction is expected to be in

During the "14th Five-Year Plan" and "15th Five-Year Plan" periods, it will be accelerated

The pressure of new energy power consumption has intensified

New energy power generation is the main force
to achieve the strategic goal of carbon peak and carbon neutrality.
In order to achieve the goal of "non-fossil energy installed capacity accounted for more than 60% in 2030 and more than 95% in 2060", a large number of UHV construction is still needed to make up for the shortcomings of new energy transmission channels
.

During the "14th Five-Year Plan" period, the nine clean energy bases and wind power photovoltaic bases plan to install 665 million kilowatts and 200 million kilowatts
.
By the end of 2021, 304 million kilowatts
had been built at the nine bases.
Large-scale wind power photovoltaic base projects focusing on deserts, Gobi and desert areas will be put into operation from 2022, which will intensify the pressure
on parts of the west and north.
Relevant agencies expect that the inter-regional and inter-provincial power flow will increase from 220 million kilowatts in 2019 to 360 million kilowatts
in 2025.

UHV is still the focus of investment in the power grid

By the end of 2021, China had 39 UHV projects in operation with "15 interchanges and 18 straight" and "4 interchanges and 2 straights" under construction, with a total length of more than 50,000 kilometers
of UHV lines under construction.
Among them, the State Grid has a total of 35 under operation and 4 are under construction
.
China has surpassed the electrical powers such as Europe and the United States, and has become the country with the longest UHV transmission line, the most complete technology and the largest number of patents in the world
.

According to data from research reports of relevant institutions, during the "13th Five-Year Plan" period, UHV investment totaled 346.
2 billion yuan, accounting for 13.
82%
of the total investment in the power grid.
During the "14th Five-Year Plan" period, 12 new UHVDC projects need to be added to the northeast, Mengxi, Shanxi, northwest and southwest DC transmission channels, with a total investment of about 260 billion yuan
.
In the same period, 16 UHV AC projects still need to be built to improve the AC synchronous power grid, with an investment of about 190 billion yuan
.
The "15th Five-Year Plan" UHVDC transmission project investment is about 380 billion yuan, supporting UHV AC project investment is about 210 billion yuan
.
With the gradual landing of the project, the demand
for corresponding equipment in converter stations, transmission lines and other links will be further stimulated.

UHV construction of the main force

From the world's first commercially operated UHV AC project to the current UHV transmission project with the highest voltage level, the largest transmission capacity, the longest transmission distance and the most advanced technical level in the world, Far East Smart Energy Co.
, Ltd.
(company abbreviation: Far East Stock Code: 600869) has witnessed China's UHV along the way, all the way to grow and the most brilliant
with timely and ultimate products and services.

UHV projects span a large area, the environment is complex and harsh, and transmission lines may face strong winds, ice cover, large spans, large height differences and other environments
.
In response to these problems, Far East has successively developed a series of products such as large-section steel-core aluminum stranded wire (720mm², 900 mm², 1250 mm²), 1250 mm² energy-saving wire, heavy ice area wire, long-span wire, low-wind pressure conductor, 1660 mm² carbon fiber composite core conductor, etc.
, to provide overall solutions
for UHV projects with different use needs and application scenarios.
The corresponding products have been favored
by national key UHV transmission projects.

The strategy of "carbon peaking and carbon neutrality" is an opportunity of the times for the development of China's UHV, Far East will take advantage of the momentum, continue to adhere to innovation-driven, technology-led, timely and ultimate products and services on the new journey, move towards the global strategic goal of "one of the best", lead the high-quality development of the industry, and help the construction
of a manufacturing power.
