report on domestic rate on wind turbine components

Please, Log in or Register to view URLs content!


offshore power converter is 100% domestic.
power generator is 90% domestic
bearings & gearboxes are increasingly domestic
Even offshore power transformers have full developed domestic options, even if localization rate is still below 25%


looks like Envision is the one that developed 66kV for offshore applications.

What’s the localization rate for land based turbines?

What’s the localization rate for land based turbines?
you mean Heavy duty Gas turbines ??

on February 28 that today, the first prototype of the 300-megawatt F-class heavy-duty gas turbine with independent IP rights developed by China rolled off the assembly line in Shanghai Lingang. It consists of 5 major systems and more than 50,000 parts.

the 300-MW F-class heavy-duty gas turbine that went offline this time was developed by more than 200 companies, scientific research institutes, universities, etc. from 19 provinces and cities including Beijing, Liaoning, Shanghai, and Jiangsu.

from raw material to components manufacturing to hot parts and testing, A to Z all process done in China and by the Chinese firms.

for example, that domestically produced 300MW F-class heavy-duty gas turbine blade master alloy (UGTC47) material and purified smelting technology have been developed, forming a casting high-temperature alloy with completely independent intellectual property rights that is suitable for the long life requirements of gas turbines, which is at the same level as similar foreign technologies..

*****************************************************************************************************

last year, DONGFANG TURBINE CO.,LTD rolled off 50MW F-class gas Turbine from assembly line. each and every part/component and process done by the company itself.. they have 80MW/100MW heavy duty gas turbines coming up

*******************************************************************************************************

400MW H-class super heavy duty Gas turbine bidding has been announced..
