Chinese firm delivers self‑developed core casting for world's most powerful onshore wind turbine_我的网站

一 |     配备 M2 芯片的新款 iPad Pro 于昨日推出，但是屏幕材质依然没有发生变化，11 英寸型号依然没有跟进采用 mini-LED 材质。

二 | 苹果于 2021 年 4 月在 12.9 英寸 iPad Pro 上首次装备 mini-LED 显示屏，尽管有传言称 11 英寸型号也会跟进，但这并没有发生。

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.

。据报道，与 mini-LED 技术相比，苹果计划使用的 OLED 显示器将包括两层串联结构，其中有两个红色、绿色和蓝色发射层，可以提高亮度。OLED 显示器的电源效率也更高，这有助于延长电池寿命。
