Development process
2011
On January 7, 2011, Jiangsu Jinhai Wind Power Technology Co., Ltd. was incorporated in Funing Economic Development Zone, Yancheng City, Jiangsu Province
On March 4, 2011, the first 3000kW fan reverse balance flange tower was successfully installed in the intertidal zone of Hutou cliff, Laizhou Bay, Shandong Province. Meanwhile, the flange stress and bolt looseness were tracked and measured
2010
On November 8, 2010, the concrete pouring of the first 3000kW wind turbine intertidal prestressed anchor bolt foundation was completed
On May 25, 2010, Jinfeng, Jingneng, Tongji University, Tianyuan and Guoshui Baotou jointly measured the bolt preload and tower vibration characteristics of the counter balanced flange tower in wulanyiligeng wind field of Jingneng
On May 10, 2010, Jinhai reverse balance flange was evaluated as a national key new product by the Ministry of science and technology, Ministry of environmental protection, Ministry of Commerce and General Administration of quality supervision, inspection and quarantine
2009
