Heavy! Far East Cable's new offshore wind power products help build a "big country heavy weapon"

As a clean energy technology that best matches the resource endowment of coastal areas, offshore wind power has received strong support from coastal areas, offshore wind power planning and support policies have been introduced one after another, and a large number of offshore wind farm projects have been landed, such as Fujian Fuqing Xinghua Bay Phase II offshore wind farm
.

The wind farm innovatively used China's first 10 MW offshore wind turbine, ranking second in the world in single-unit capacity and first in the Asia-Pacific region at that time, breaking a new record
for China's offshore wind power single-unit capacity.
As a "big country heavy weapon" independently developed by China, the unit has applied a number of advanced technologies with independent intellectual property rights for the first time, including electric dual-drive pitch technology, permanent magnet direct drive generator technology, full-power converter technology, etc
.

Far East Cable Co.
, Ltd.
, a subsidiary of Far East Smart Energy Co.
, Ltd.
(hereinafter referred to as Far East Stock Code: 600869), participated in the construction of the unit, providing ultra-large offshore wind power high-voltage torsion-resistant cables for wind power towers, timely and ultimate products and services, and fully ensuring the safe and stable operation
of the unit.

The center height of the hub of a 10 MW offshore wind turbine is about 126 meters above sea level, which is equivalent to the height of a 40-story residential building; The blade diameter of the fan is 185 meters, which is equivalent to the width of three Boeing 747s side by side; The wind wheel sweeping area is equivalent to 3.
7 standard football fields
.

After the unit is put into use, under the condition of wind speed of 10 m/s, a single unit can transmit 40 million degrees of clean electricity per year, which can reduce coal consumption by 12,800 tons and carbon dioxide emissions by 33,500 tons, which can meet the normal electricity needs
of 20,000 families of three.

The large blades place extremely high demands
on the strength of the tower and the drive of the pitch system.
At the same time, high power also means greater power transmission pressure
.
After ingenious research and development, Far East Cable has launched ultra-large offshore wind power high-voltage torsion-resistant cable, from drafting, design, testing to pilot, production, supporting and laying, and has been authorized a number of related invention patents, which is far ahead in this field and meets the strict requirements
of unit operation.

In order to solve the problem of torsion resistance and high voltage resistance of offshore high-voltage cables, Far East Cable has developed ultra-purification continuous production technology of insulation materials, which prolongs the service life under harsh working conditions while ensuring the strength of the cable, and designs a new intelligent extrusion process, which further reduces the process loss and greatly improves the product quality
.

After 3 years of research and development, the ultra-large offshore wind power high-voltage torsion-resistant cable has successfully passed the technical appraisal of the expert team headed by Academician Qiu Aici, and the technical level has reached the international lead
.
The successful development and application of this product indicates that Far East Cable has strong technical advantages in offshore wind power supporting links, and also lays a solid foundation
for the comprehensive layout of offshore cables.

Through the verification of the structural design, insulating material development, and resistance to harsh working conditions of torsion-resistant cables, Far East Cable has established a complete set of standard systems, and is fully capable of supporting deep-sea ultra-large offshore wind turbines
.

In the future, China's offshore wind power construction will move towards the far sea, deep sea and high-power wind turbines, Far East Cable will continue to increase research and development efforts, and layout marine cable research and development and laying technology development, further promote the development of offshore wind power industry chain, promote China's energy reform and transformation, and help achieve the "30·60" dual carbon goal
