Two other Chinese wind generators makers, Titan Wind Energy (Suzhou) Co and Shanghai Taisheng Wind Power Equipment Co Ltd, also expressed concern, saying any anti-dumping duties by the US could hurt their prospects in a growing market.
However, according to industry insiders, the majority of China’s windmill power companies will not be affected by the investigation.
“First, the production of wind-towers doesn’t contain too much technology,” said Shi Pengfei, vice-president of the Chinese Wind Energy Association. “Second, the export market is still on a small scale for Chinese manufacturers.”
He said the Chinese companies can tap the growing domestic market even if the US stops imports of Chinese wind towers.
The towers are most often exported to the US because of lower production costs in China. On average, the cost of a wind tower accounts for 20 percent of a wind turbine, which cost $600,000 each. The price often depends on fluctuations in the cost of steel, which is the main production material.
Wind-tower manufacture doesn’t require a large amount of technology, so Chinese companies have cost advantages because of the lower labor costs in China home wind generator, said Li Shengmao, a senior industrial researcher at the CIC Industry Research Center.
He added that, in addition to the companies listed the investigation, others manufacturers should also be prepared for possible probes.

Generator bearing of electric corrosion is when it was spinning of bearing internal is energized, the current through the rotation contacting part very thin oil film generated when sparks, make the bearing surface occurs local molten phenomenon. In order to prevent corrosion occurrence, the use of the insulation good ceramic material production ceramic bearing. In this bearing structure, because in bearing outer ring has a layer of spray plating ceramic membranes or resin film, make its insulation than traditional bearing has the following advantages:
Holding long-term stable insulation;
Bearing is easy to install,
Due to temperature less, improving the lubricant life.
Special to note is traditional bearing due to happen electric corrosion, must early for replacement. And insulation ceramic bearing due to its good insulation, can prevent electric corrosion occurrence. Large wind generators cabin is apart from the ground up, bearing produces attaint about 100m replaced, the operation is very difficult, and to the high cost of maintenance cost. And the wind generator for maintenance extended shutdown, also reduced the power of time. Insulation ceramic bearing not only prevent wind generators’ premature damage and reduce the maintenance cost and improves the reliability of the wind generator overall.
