In late June 2026, 2026 Orient Cable completed the design, supply and installation of delivered a 66 kV dynamic subsea cable for China Three Gorges’ the 16 MW Sanxia Linghang floating‑wind demonstration platform Sanxia Linghang, located about 70 km off Yangjiang, Guangdong. The cable, built to withstand extreme waves and a 25‑year service life, marked platform, the first dynamic such cable for floating wind in China and supported the platform’s effort to prove large‑scale floating‑wind viability. A month later, in China. In July 2026, 2026 China floated Three Gorges launched a world‑record ±500 kV offshore DC converter station – the station, dubbed “sea heart” – roughly heart”, about 100 km offshore. Coupled with off Yangjiang, connected by an 88.8 km flexible‑current DC subsea cable and a 180 km on‑shore line, the system will deliver about projected to supply roughly 60 billion kWh of clean electricity power annually to the Guangdong‑Hong Kong‑Macau Greater Bay Area, demonstrating a high‑capacity, deep‑sea power transmission solution for offshore wind. Together, these projects show a rapid progression Area. By 29 July 2026 the facility—now referred to as the “Heart of Offshore Wind”—entered its final submarine‑cable linking and joint testing phase. The 2‑GW, 500‑kV station will collect electricity from prototype floating‑wind cabling 163 offshore turbines, convert 66 kV AC to large‑scale, high‑voltage DC transmission infrastructure in 500 kV DC, and is expected to deliver about six terawatt‑hours of renewable electricity each year, cementing China’s offshore wind sector. high‑capacity deep‑sea transmission roadmap.
