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
.
In recent years, the installed capacity of offshore wind power connected to the grid and the new installed capacity of the grid have continued to grow
.
In 2021, the cumulative installed capacity of offshore wind power was 26.
39 million kilowatts, and the new installed capacity was 16.
9 million kilowatts
.
However, due to the limitations of construction conditions and operation and maintenance conditions, the development of offshore wind power is inevitably limited
.
In particular, some key components have been put to the test
.
As an important component of wind turbine power transmission, the safety and reliability of wind power cables are very important, which directly determines the operating life of wind turbines and is related to the normal operation
of offshore wind farms.
High reliability has become the main direction
of offshore wind power cable development in the future.
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), entered the field of wind power as early as 2002, laid out in advance, in-depth research, relied on strong technical research and development and manufacturing strength, and developed a series of products for offshore high-power new wind turbines through continuous innovation and breakthroughs, boosting the development of
offshore wind power.
Offshore wind turbine external transmission of power mainly relies on submarine cables, submarine cables account for about 5% of the cost of wind farms, how to reduce the cost of submarine cables has become a key part of offshore wind power to achieve parity, but 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.
On this premise, 33kV as the voltage level of the on-site submarine cable has gradually become a bottleneck restricting the design of the submarine cable system, and the 66kV voltage level has begun to be sought after, and many wind farm projects that are planning or have won the bid will adopt the 66kV voltage level scheme
.
Once a 66kV high-voltage submarine cable is used, the number of submarine cables required can be reduced by 30%, which can greatly reduce the cost of submarine cable
.
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 torsional cables, which is another major breakthrough
in the design and manufacture of high-voltage torsional cables for offshore high-power wind turbines after 35kV wind power torsion-resistant flexible cables.
66kV high voltage torsion cable by using 66kV high electrical performance ethylene propylene insulation material and customized structural design, effectively reduce the insulation thickness and cable weight, but also more advantages in performance, not only meet the -40 °C and 2000 times torsion requirements, but also meet the offshore high temperature, high humidity, high salt spray concentration operating environment requirements, and successfully passed the third-party authority test
.
It is worth mentioning that the technical specification of TICW22-2022 "Twist-resistant flexible cable for wind power generation with rated voltage 66kV (Um=72.
5kV)" participated in the formulation of Far East Cable 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 cable.
After continuous innovation and breakthroughs, Far East Cable currently has a market share of 30% in the wind power segment, and has become one of the largest wind power cable suppliers in China, cooperating with and supplying foreign wind power manufacturers such as VESTAS, GE Wind Energy, Siemens Gamesa, Nordex, Suzlon and other domestic wind power manufacturers such as Goldwind Technology, Envision Energy, Guangdong Mingyang, Shanghai Electric, Yunda Wind Power, Dongfang Electric, China Haizhuang Wind Power, Sany Heavy Energy, CRRC Wind Power, Sinovel Wind Power, etc
。 Related products have been applied in China, Chile, Spain, Vietnam, Mexico, South Korea, South Africa, the United States, India and other countries, providing a strong guarantee for wind turbines and winning unanimous praise
from customers.
Offshore wind power is the main direction of the future development of the domestic wind power market, and the development process of ultra-high power units is getting faster and faster, and the requirements for transmission systems are getting higher and higher
.
The gradual increase in voltage levels will further reduce the cost
of offshore wind farms.
Far East Cable successfully trial-produced 66kV high-voltage torsion cable, once again seized the opportunity, in the forefront of the industry, the future will continue to make efforts, relying on its own strong R & D and manufacturing strength, developed more high-voltage level torsion-resistant cable products, for the development of offshore wind power to contribute Far East wisdom and strength
