 I. Major industry exhibitions and forums

Shanghai International Transformer New Process, New Materials and Production Equipment Exhibition (2025.6.11-13)

Focus direction: intelligent transformation, green low-carbon technology, amorphous alloy application, digital factory construction, etc.

Highlights:

Siemens Energy shares the practice of digital twin platform for transformers

Haihong Electric showcases the innovative achievements of amorphous alloy transformers with three-dimensional coiled cores

publishes the Research Report on Digital Factory Construction to promote the transformation of the industry into a ‘new quality and efficiency’ industry.

Yantai International Transformer Equipment and Technology Exhibition

Focusing on transformer components, insulation materials and intelligent manufacturing equipment, covering silicon steel, amorphous alloys and other core materials supply chain8.

Secondly, the key project of welcoming the peak for the summer was put into operation.

Upgrading of Huai'an 500kV Shanghe Substation in Jiangsu

Two domestic 1000 MVA main transformers were put into operation on June 15, replacing imported equipments that had been in operation for 26 years, with an additional power supply capacity of 500 MVA, strengthening the power grid of East China. "Strengthening the capacity of East China Power Grid to send electricity from the north to the south.

The project responds to the national equipment renewal policy and realises the replacement of the core equipment by localised ones.

Putian, Fujian 110kV Xianlai Substation was put into operation ahead of schedule.

The project was put into operation 5 months ahead of schedule, and equipped with two 50MVA main transformers, solving the problem of single-line power supply in Xianyou County and improving the reliability of the regional power grid.

Third, technological innovation and patent breakthroughs
