Located on the southwest coast of Guangdong, Yangjiang boasts an 11,900-square-kilometer sea area and a 504.35-kilometer coastline. Offshore wind power serves as the core resource and driverfor Yangjiang's development.
In recent years, Yangjiang has developed into a key national base for the offshore wind power industry. It has experienced rapid growth, bolstered by continuous innovation in green energy and marine equipment manufacturing.
Yangjiang High-tech Industrial Development Zone, home to the city's most concentrated and complete wind power industry chain, is forging a 100-billion-yuan wind power equipment manufacturing industrial cluster. The installed and under-construction capacity of offshore wind power has reached 13 GW. It has attracted leading industry players, including China Three Gorges Corporation, China General Nuclear Power Group, Mingyang Smart Energy, Goldwind Science & Technology, and Oriental Cable. Join GO Guangdong to explore Yangjiang's dynamic offshore wind power development.

A "medical center" for offshore wind power equipment
Established in the Yangjiang High-tech Zonein June 2018, CGC Guangdong Offshore Wind Power Testing and Certification Center serves as the sole national-level platform for public testing, inspection, and technical service of offshore wind power equipment in China.
In the center, advanced wind power testing equipment operates at peak efficiency as engineers and researchers collaborate to conduct the most precise and high-standard "check-ups" of offshore wind power equipment.
Each wind turbine blade undergoes testing, including fatigue life, static load, ultimate load, and 8 million cycles of load. By simulating extreme conditions such as offshore typhoons and wave impacts, the center ensures the blades can operate safely throughout their lifespan.

The center's blade laboratory is the world's first to conduct full-scale tests on blades up to 150 meters in length, advancing global detection capabilities.

Beyond blade testing, the detection also includes lubricating grease analysis for wind power equipment. Under the microscope, grease samples are magnified thousands of times. Serving as a "blood test", technicians meticulously analyze the oil condition to detect the health status of operating wind power equipment. This allows more accurate prediction on blade performance in practical operation.

To date, the center has established full life-cycle inspection and testing services, covering raw materials, components, complete machines, and in-service units. Its test results are recognized and adopted by over 30 countries worldwide, providing the offshore wind power industry at home and abroadwith a solid guarantee and crucial technical support.

Deep-sea "arteries" for offshore wind energy
Submarine cables function as the vessels and nerves of an offshore wind power system, transmitting stable electricity and relaying equipment operation and environmental monitoring signals.
Located in the Port Industrial Park of Yangjiang High-Tech District, Orient Cable High-End Submarine Cable System Southern Industrial Base plays a pivotal role in Yangjiang's wind power industry chain. A cable belt which is hundreds of meters long runs through the plant area, connecting to the base's dedicated wharf. The submarine cables produced here will be transported from the port for underwater installation, laying power transmission lines between land and sea.

Its operating company, Guangdong Orient Submarine Cable Co., Ltd., has achieved multiple technological breakthroughs in Yangjiang. These include the successful R&D and application of the world's first 500 kV AC three-core submarine cable and the undertaking of the world's first long-length 330 kV submarine cable system project. Yangjiang has realized a "local production with direct on-site delivery" for submarine cables. The first batch of locally manufactured cables has been deployed in local offshore wind power projects, such as Qingzhou Phase V, significantly boosting construction efficiency.
