CHONGQING — A giant wind turbine developed by China has rolled off the production line in the southwestern municipality of Chongqing.

The turbine, coded H140-3MW, has a diameter of 140 meters, according to HZ Windpower, a subsidiary of the State-owned China Shipbuilding Industry Corporation.

The turbine has the longest diameter among all the turbines of the same level. It can generate 3,000 kilowatt hours of electricity per hour at a wind speed of 9.6 meters per second, the company said.
