On the evening of July 7, the “heart” of the 10,000-ton SanShan Island offshore converter station was unmoored at the Zhenhua Wharf in Nantong, Jiangsu, and set sail for the waters off Yangjiang, Guangdong. This “offshore power heart” is expected to arrive in the Yangjiang area in the coming days, where it will be integrated with the Yangjiang SanShan Island Offshore Wind Power Flexible DC Transmission Project.

The Sanshandao Project is China’s first offshore wind power project to integrate onshore and offshore flexible DC transmission, and it is currently the world’s largest offshore wind‑to‑DC transmission project. Upon commissioning, it will be able to deliver approximately… of clean electricity annually to the Guangdong–Hong Kong–Macao Greater Bay Area. 6 billion kWh, equivalent to saving 1.74 million tonnes of standard coal and reducing carbon dioxide emissions by approximately 4.63 million tonnes (according to a report on Borui Power’s official WeChat account).

As a provider of on-site fiber-optic cable installation and testing services, Participant Guangruyuan Optoelectronics is leveraging its practical expertise to ensure the reliable communication infrastructure of this “super project.”

Two major projects, one mission.

The Guangdong Yangjiang Sanshandao Offshore Wind Power Flexible DC Transmission Project and the Guangdong Yangjiang Offshore Wind Power Project are part of Guangruyuan Optoelectronics. Key projects for engineering services in 2026

In the Sanshandao Project, we provided on-site guidance and testing services for the installation of optical cables. Following final assembly onshore, the converter station was floated as a whole to the offshore installation site. With a voltage rating of ±500 kV and a capacity of 2 million kW, the project placed exceptionally stringent demands on the precision of on-site cable laying and the reliability of splicing.

In the Yangjiang Offshore Wind Power Project, the team overcame challenges such as a short window for offshore operations and a complex construction environment, successfully completing the cable laying, connection, and commissioning tasks to a high standard.

Both major projects are located in the waters off Yangjiang, Guangdong, and together they will support clean energy supply for the Guangdong–Hong Kong–Macao Greater Bay Area. To date, the Yangjiang project has been successfully completed, while the Sanshandao project is currently in full swing, striving to meet this year’s milestones. October production launch target.

Regional Significance: Green Power Enters the Bay, Fueling Powerful Momentum

The Sanshandao Project is dubbed a “super‑scale engineering feat” not only because of its technical complexity, but also due to its far‑reaching impact on the regional energy landscape.

For the Guangdong-Hong Kong-Macao Greater Bay Area, Upon completion, the project will erect an energy bridge spanning over a hundred kilometers, converting powerful offshore winds into clean electricity and delivering it directly to the Greater Bay Area. Each year… Six billion kilowatt-hours of clean electricity is equivalent to meeting the annual power needs of approximately 2 million households (according to a report on Borui Power’s official WeChat account), serving as a robust, clean energy driver for the Bay Area’s economic development.

From the perspective of national energy strategy This project breaks with conventional offshore wind power transmission paradigms, enabling the large-scale, high-efficiency, long-distance delivery of deep-sea wind energy to load centers, thereby providing a world-class solution for transmitting power from deep-sea wind farms.

From the perspective of the industrial chain The project has strongly catalyzed the development of related industrial chains, including high-end equipment manufacturing and offshore construction. From Borui Power’s energy‑self‑balancing converter valves, to FiberHome Communications’ custom‑designed flexible DC converter valve control‑specific optical cables (as reported on FiberHome’s official WeChat account), to Guangruyuan Optoelectronics’ on‑site cable‑laying and testing services—every link in the chain is contributing its specialized expertise to the “dual carbon” goals.

Pragmatism as Our Pen: We Are on the Front Lines

As a party deeply involved in the project’s construction, The company, Guangruyuan Optoelectronics, integrates the upstream “core”… Electricity “Device” and “ Control The “signal neuron” is the critical link that seamlessly integrates safety, precision, and efficiency.

Guangruyuan Optoelectronics to will Standing as a steadfast cog in the national energy transition, we bring our expertise and unwavering commitment to every project site, contributing to the integration of green power into the bay area and to the achievement of the “dual carbon” goals.

Going forward, the company will continue to deepen its expertise in smart grids and Light In the communications sector, with a positioning of “small but exquisite, specialized and refined,” it serves an increasing number of major national energy projects.

A tribute to every Guangruyuan employee fighting on the front lines in Yangjiang.
The sea breeze sweeps fiercely, and practical action is the answer.
