SINGAPORE, July 19, 2024 /PRNewswire/ -- China Yuchai International Limited (NYSE: CYD) ("China Yuchai" or the "Company") one of the largest powertrain solution manufacturers through its main operating subsidiary in China, Guangxi Yuchai Machinery Company Limited ("Yuchai"), today announced that Yuchai's subsidiary, Guangxi Yuchai Foundry Company Limited ("Yuchai Foundry") made a significant advancement in the wind energy sector with the launch of the QT700-10 turbine fan main shaft. This innovative main shaft was developed and manufactured using QT700-10 high-strength and high-elongation ductile iron material proprietarily developed by Yuchai Foundry.

In the context of global energy transformation and carbon emissions reduction, wind power, as a major force in clean energy has extensive applications. The first batch of QT700-10 turbine fan main shafts has been running smoothly during the wind farm tests for 6 months following the successful design, manufacturing and test operations. The test results of these advanced turbine fan main shafts have been well received by customers, including leading domestic wind turbine manufacturers. Yuchai Foundry is now in position to take orders and has expanded its production capacity of the QT700-10 turbine fan main shaft to an annual output of 1,000 units.

The difficulties in developing the QT-700-10 main shaft were overcome through the efforts of Yuchai Foundry's research and development team. The materials used in the QT700-10 turbine fan main shaft feature high strength, high plasticity, and improved low-temperature fracture toughness. The overall weight has been reduced by 15%-30% compared to conventional main shaft products.

The QT700-10 turbine fan main shaft can be used with wind turbine capacity of 5MW and above. A typical 5MW wind turbine will generate 5,000 kilowatt-hours of electricity per hour, creating considerable economic benefits.

Mr. Weng Ming Hoh, President of China Yuchai, commented that, "We continue to leverage our strong research and manufacturing capabilities to broaden our offerings in the clean energy sector. The QT700-10 turbine fan main shaft represents a leap forward in the design and manufacturing of a component critical to wind power generation, and demonstrates our commitment to making technological advancements to power the renewable energy sector."
