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.

特斯拉股价在隔夜再度大幅下跌逾6%，因马斯克表示，在全球经济疲软的情况下，这家电动汽车制造商获得需求“有点困难”。
B | 马斯克预计，由于运输能力有限，特斯拉将无法实现年度交付目标。不过他同时也表示，其当前季度的“需求非常好”。由于财报业绩未达预期和对未来需求展望较谨慎，华尔街多名分析师周四下调了对该公司的目标价。事实上，这已非马斯克首度对经济衰退的前景发表看法。早在今年5月时，马斯克就曾表示美国经济“很可能”已处于衰退。当时在谈及经济衰退可能的持续时间时，马斯克表示，“这可能会是一段艰难的日子，我不确定衰退的持续时间，也许是一年，也许是12-18个月。”批评美联储值得一提的是，在本周三特斯拉的财报电话会议上，马斯克还不同寻常地对美联储颇有微词。目前，美联储正在进行数十年来最激进的加息行动，以遏制失控的通胀。马斯克表示，美联储正在过高、过快地提高利率。他甚至看到经济在部分领域存在通缩的迹象。马斯克称，尽管特斯拉公司发现一些领域的价格仍在上涨，但总体而言，价格下跌的地方已经比上涨的多。“从长远来看，大宗商品的价格已经下跌了很多。尽管在有些领域，例如电池级锂的价格仍然很高。”马斯克表示，美联储忽略了这些大宗商品价格的最新变化。“如果你从后视镜看出去，美联储的决定是有意义的，但如果你从前挡风玻璃看出去，就没有任何意义。他们应该从前挡风玻璃看事情。”除了马斯克外，近期不少知名人士也对经济衰退的前景发出过警告。例如，仅次于马斯克的全球第二大富豪、亚马逊创始人贝佐斯日前就警告称，美国经济可能正走向衰退，并建议美国人准备好迎接暴风雨。
C | 摩根大通首席执行官杰米·戴蒙近期也表示，形势“非常、非常严峻”，美国经济可能在未来6个月内陷入衰退。
