The core castings for the world's most powerful onshore wind turbine in terms of single‑unit capacity have recently been delivered by a Chinese company, marking a technological breakthrough in the large‑megawatt onshore wind power castings, domestic news portal stdaily.com affiliated with Science and Technology Daily reported on Wednesday.
Independently developed by Dalian Huarui Heavy Industry Group Co., Ltd. (DHHI), the delivered components include the bearing housing and base castings for 15 MW doubly fed onshore wind turbines. The components need to bear the huge gravity, wind loads and alternating loads transmitted from the blades and hub, and transfer the loads to the generator, ensuring steady rotation of the main shaft. 
The products passed all customer inspections and assessments in one go and were officially delivery, stdaily.com reported.
Adopting an advanced modular design, the turbine components delivered can support flexible power adjustment ranging from 13 MW to 16 MW, enabling adaptive operation to varying and complex wind conditions across diverse regions, the report said.
The turbine's rotor diameter ranges from 240 meters to 260 meters, and are compatible with tower heights of 135 meters to 190 meters, delivering a maximum swept area of 53,000 square meters, roughly 8 standard football pitchs (105m×68m). This places the unit's overall performance among the world's top-tier.
Such super-large castings place extremely high demand on material properties, casting processes, dimensional accuracy and internal quality. The successful validation and delivery of the products therefore demonstrate the research and development, as well as manufacturing capabilities in super‑large wind power castings, stdaily.com reported.

。    近日，一段广西“南宁楼房倒塌”的不实视频在社交平台上传播，视频配文称“南宁白沙大道一大楼倒塌，人像下饺子一样往下掉”。　　谣言5年前就已出现　　上述有关说法附有一段16秒左右的视频。由前后两部分拼接而成。

二 | 前一部分的内容显示，一栋高楼顶部出现裂缝，部分建筑在倾斜后迅速坠落至地面。另一部分的内容则显示，滚滚黄尘中，有人大叫“一栋大楼掉下去了，南宁白沙大道啊”。该说法及视频近期在外网的点击量合计已超过700万次，且多年来曾数度被转载。　　真相　　经核实，该视频拍摄的“楼房倒塌”实为2019年4月白沙村一危房正在进行安全拆除，“楼房倒塌”“人往下掉”等说法不实。2019年官方曾对该谣言进行辟谣，系旧谣新传。（中国小康网综合广西互联网辟谣平台、看看新闻、极目新闻）。
