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

A |     ROME -- Italian Premier Giorgia Meloni announced Friday that she is separating from her partner and the father of her young daughter after nearly a decade together.In a statement posted on social media, Meloni said her relationship with Andrea Giambruno had ended. She said their paths had diverged “for some time.” The announcement came after Giambruno, an on-air television personality, was caught on audio seemingly making lewd remarks to colleagues.An Italian satirical news program, Striscia la Notizia, aired two nights' worth of programming on Giambruno this week, using backstage clips and audio. Striscia is a primetime program of the Mediaset broadcaster of the late Silvio Berlusconi, whose Forza Italia party is a junior partner in Meloni’s government.This week marks the first anniversary of Meloni's government, Italy's first headed by a woman and first hard-right-led administration since the end of World War II.Meloni, who was raised by a single mother after her father abandoned the family, and Giambruno share 7-year-old Ginevra. Meloni had previously described Giambruno as a “fantastic” and very present father who complemented her in caring for their daughter. In her 2021 memoir “I am Giorgia,” she said Giambruno wouldn’t balk if she was working and he had to step in, though she complained that he was messier than she.In her statement, Meloni thanked Giambruno for their relationship and daughter and she would defend their friendship. “And I will defend, at all costs, a 7-year-old girl who loves her mother and loves her father, as I was unable to love mine.”She also hit back at the media coverage that preceded her announcement, blasting “all those who hoped to weaken me by hitting me at home.”。

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.
