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.

D | “早上好！”一批学生每星期都会来到一家乐龄日间护理中心同年长者交流。职总优儿学府幼乐园学生陈恩浩说：“喜欢（为什么喜欢？）因为我喜欢玩那个游戏，跟阿公阿嫲我教他们。”这天的活动是宾果游戏，学生教导年长者怎么玩，长辈则教他们游戏中出现的福建动物名称。职总保健乐龄日间护理中心跨代交流计划参与者，毛润环说：“很开心，我喜欢小孩子，可爱天真活泼。

E | 跟他们讲要好好做个好孩子，要听话要勤劳读书。

F | ”跨代交流计划拉近两代的距离，当老师在活动进行一半时说当天有小朋友生日，全场马上为她庆生。全岛有159家分校的幼乐园指出在跨代交流计划下，学生每年最少有10到12次同年长者交流的机会。他们不仅从长辈的经验中学习到知识，也变得更有耐心和有同理心。

G | 职总优儿学府幼乐园总经理程爱玲说：“现在所做的一些活动上也常常会做一些更改跟一些邀请其他的工作团队的人员，或者一些机构来参与我们的工作。

H | 为小朋友讲一些历史，为小朋友说一些他们之前在新加坡的生活到底是怎么样。那种的跨代交流计划其实也很不一样，因为它是一种好像比较知识交流的。”幼乐园计划明年发布刊物，记载跨代交流计划推行十年的历程，鼓励更多跨代交流。
