85.5 kilometers offshore! China's deep-sea offshore wind power has reached a new peak! Recently, the hoisting of all wind turbines for the 800MW offshore wind power project of CTG Renewable Energy in Dafeng, Jiangsu Province has been successfully completed. As the offshore wind power project with the farthest offshore distance among China's grid-connected projects so far, this project plays a "blue movement" of the "dual carbon" era with technological breakthroughs – and Far East Cable, a subsidiary of Far East Smarter Energy Co., Ltd. ("Far East Energy", stock code: 600869), is the "power artery" delivering green energy to this deep-sea project.

Deep-Sea Breakthrough Starts a New Journey

This "green energy island" rooted in the sea area northeast of Dafeng District, Yancheng, Jiangsu, consists of four wind farms. Among them, the central point of the H8-1 wind farm site is 80 kilometers offshore, and the farthest point is 85.5 kilometers offshore, firmly ranking as the "farthest grid-connected offshore wind power project in China". A total of 98 wind turbines are installed in the project, supporting the construction of 2 offshore booster stations of 200MW and 1 offshore booster station of 400MW. The first batch of units was connected to the grid for power generation on July 4 this year.

An offshore distance of 85.5 kilometers means that construction workers spend 6 to 7 hours on a one-way trip to the sea, and multiple challenges such as open sea surges, extreme weather, and seabed sediment erosion must be overcome. Despite numerous challenges, the demonstration value and ecological benefits of the project are particularly prominent – as one of Jiangsu's first batch of offshore wind power parity demonstration projects, it marks that China's offshore wind power is entering a virtuous cycle of "technological innovation to reduce costs", laying the foundation for the implementation of inclusive electricity prices, and is a vivid microcosm of the high-quality development of the industry.

After the project is put into operation, the average annual power generation can reach 2.842 billion kWh, equivalent to saving about 860,000 tons of standard coal and reducing carbon dioxide emissions by about 2.37 million tons, which will effectively ensure the supply of clean energy and optimize the regional energy structure.

Far East's Torsion-Resistant Flexible Cables Support and Escort the Project

As a core component of the wind power system, Far East Cable acts like a "blood vessel" for power transmission and plays a vital role in this wind power construction. Far East provided 66kV high-voltage torsion-resistant flexible cables and wire harnesses for 13.6MW units.

The 66kV high-voltage torsion-resistant flexible cables and wire harnesses are tailor-made "sharp weapons" for the stable operation of high-power deep-sea units in harsh environments. As early as 2019, Far East successfully trial-produced Asia's first 66kV high-voltage torsion-resistant flexible cable for offshore wind turbines of 8MW and above. At present, Far East has launched special torsion flexible cables and aluminum alloy tower cables for wind turbines with specifications of 0.6/1kV, 1.8/3kV, 3.3/6kV, 12/20kV, 21/35kV, 26/35kV, and 36/66kV. These products feature low-temperature torsion resistance, low-temperature bending resistance, moisture resistance, cold resistance, salt spray resistance, oil resistance, UV resistance, and light weight, and have been successfully applied in many wind power projects, providing strong guarantee for wind turbines. Far East's "Cables for Wind Power Generation" won the honorary title of "Single Champion Product in Manufacturing" from the Ministry of Industry and Information Technology, a qualification only granted to enterprises with significant leading advantages in scale, quality, industrial chain layout, and R&D capabilities.

Equipped with an advanced intelligent control system, Far East's torsion-resistant flexible cables realize remote monitoring and maintenance, greatly reducing operation and maintenance costs in deep seas, and laying a solid technical foundation for the wind power industry to develop towards units of 18MW and above and voltage levels of 110kV and above. With the "hardcore strength" of manufacturing, Far East escorts the optimization of China's energy structure and the construction of a new energy system.

In the future, with continuous technological breakthroughs and industrial upgrading, China's deep-sea offshore wind power will surely embrace broader development prospects and contribute more Chinese strength to the global energy revolution.
