Siemens Energy commissions GIS at one of China’s largest offshore wind turbines

Siemens Energy commissioned an eco-friendly power transmission system complementing one of China’s largest offshore eight MW wind turbines.

The system consists of a SF6 (sulfur hexafluoride)-free gas-insulated high-voltage switchgear (GIS) called 8VM1 Blue GIS and a liquid-immersed distribution transformer with ester fluid. It is part of a demo project by Shanghai Electric, located at Shantou Haojiang onshore Industrial Park on the east coast of Guangdong, South China. The wind turbine generator is the first to run on 66 kV in China. The 8VM1 Blue GIS was specifically developed to enable higher voltage levels in wind turbines and is also the first Blue GIS operating in China.
