Far East Cable: Development of high-power wind turbine products to help the high-quality development of offshore wind power

A few days ago, the National Development and Reform Commission and the National Energy Administration issued the "14th Five-Year Plan" for the modern energy system, which clearly proposed to accelerate the development of wind power and solar power generation; Comprehensively promote the large-scale development and high-quality development of wind power and solar power generation; Accelerate the construction of large-scale wind power photovoltaic base projects focusing on deserts, Gobi and desert areas; Encourage the construction of offshore wind power bases, and promote the layout
of offshore wind power to deep-water and far-shore areas.

As a clean energy, offshore wind power has developed rapidly in China by virtue of its advantages of proximity to electricity load, stable power generation and non-occupation of land resources
.
Especially in recent years, with the continuous decline in the price of offshore wind turbines and the gradual reduction of low construction costs, offshore wind power has ushered in explosive growth
.
In 2021, the annual installed capacity of offshore wind power will be 16.
9 million kilowatts, which is 1.
8 times the total scale of previous cumulative construction, and the cumulative installed capacity of offshore wind power will reach 26.
39 million kilowatts, ranking first
in the world.

The offshore wind power industry has a lot of room for development, how to seize this new historical opportunity? Many upstream and downstream wind power companies have taken action
.
As a leading enterprise in the cable industry, Far East Cable Co.
, Ltd.
, a subsidiary of Far East Smart Energy Co.
, Ltd.
(hereinafter referred to as Far East Stock Code: 600869), has been deeply engaged in the field of wind power since 2002, and has gradually formed a perfect power supply and distribution system solution through continuous innovation and breakthrough, and focused on developing a series of products that meet the needs of offshore high-power new wind turbines to promote the high-quality development of
offshore wind power.

Offshore wind turbines mainly rely on submarine cables, which account for about 5% of the cost of wind farms, and how to reduce the cost of offshore wind power has become a key part of offshore wind power parity, and is also related to the future development of
offshore wind power.
Offshore wind farms boost the transmission power through the offshore step-up platform and transmit it to land, each booster platform is combined with a collector line, the higher the voltage level of the line, the more the number of wind turbines that can be accommodated, and the less
submarine cable is used.

In the past, wind farm projects mainly used 33kV voltage level solutions, but now they can no longer meet the design requirements and have become a bottleneck
.
On this premise, 66kV voltage levels are sought after, and many wind farm projects that are being planned or have won bids will use 66kV voltage level schemes, because the use of 66kV high-voltage submarine cables can reduce the number of submarine cables by 30%, which greatly reduces the cost
of submarine cables.

In order to better adapt to the market and customer needs, in view of the characteristics of complex operating environment, high voltage resistance level and frequent torsion of high-voltage torsion-resistant cables for offshore wind power, Far East Cable took the lead in successfully developing 66kV high-voltage torsion-resistant flexible cables, which is another major breakthrough
in the design and manufacture of high-voltage torsion-resistant cables for offshore high-power wind turbines after 35kV wind power torsion-resistant flexible cables.

66kV high-voltage torsion-resistant flexible cable by using 66kV high electrical performance ethylene propylene insulation material and customized structural design, can effectively reduce the insulation thickness and cable weight, and has more advantages in performance, not only to meet the -40 °C and 2000 times of torsion requirements, but also to meet the operating environment requirements of high temperature, high humidity and high salt spray concentration at sea, and successfully passed the third-party authority test
.

It is worth mentioning that the technical specification of TICW22-2022 "Rated voltage 66kV (Um=72.
5kV) twist-resistant flexible cable for wind power generation" was officially released, which played a positive role in the cable selection and safe operation of high-power offshore wind turbines, and also highlighted Far East Cable's leading position
in the research and development of 66kV high-voltage torsion-resistant flexible cable.

Relying on strong technical research and development and manufacturing strength, Far East Cable currently occupies 30% of the wind power market segment, has become one of the largest wind power cable suppliers in China, and cooperates with and supplies foreign wind power manufacturers such as VESTAS, GE Wind Energy and Siemens Gamesa and domestic wind power manufacturers such as Goldwind Technology, Envision Energy, Guangdong Mingyang, Shanghai Electric and Yunda Wind Power
.
Related products have been applied in China, Chile, Spain, South Korea, the United States, India and other countries, providing a strong guarantee for wind turbines and winning unanimous praise
from customers.

China's coastline length is more than 18,000 kilometers, offshore resources are very rich, and adjacent to the southeast coastal power load area, convenient for energy consumption, offshore wind power has become an important strategic development route
of China's "14th Five-Year Plan" energy transformation.
As a leading cable enterprise, Far East Cable will continue to promote the development of wind power industry with core independent intellectual property rights, and contribute to comprehensively improving the technical level of China's wind power generation system and related supporting industries, international market competitiveness and the high-quality development of offshore wind power
