February 28，Sany Heavy Energy 8.5-11MWThe first wind turbine with an impeller diameter of 230 meters on the onshore platform was successfully launched in Beijing Nankou Intelligent Manufacturing Industrial Park.。This is the largest offline power in the world.、Onshore wind turbine with the largest impeller diameter。

Li Qiang, General Manager of Sany Heavy EnergyAttend the offline ceremony and deliver a speech。First of all, he thanked the product R & D team for their hard work.，R & D team technical fortification、Keep forging ahead，Fully carry forward the Trinity people“Be jealous of slowness”Work style。Nowadays, China's wind power has entered the era of parity.，Only by constantly strengthening technological innovation and breakthroughs，Continuously reduce the cost of electricity，Only in this way can the return on investment in wind farm development be guaranteed.，Only in this way can we enhance the market competitiveness of wind power in all forms of power supply.。

01Advanced Technology Leads the Megawatt Era

According to product manager Wu Shengfei.，The platform is aimed at“Three North”Wind power market development，The power is 8.5-11MW，Impeller diameter 230 m，The swept area is 41548.m²，Equivalent to six standard football fields，Wind-catching ability、Power generation capacity has been greatly improved.。

It is the first time for the platform unit to adoptDouble-box transformer upper setting technology，Use 2 sets of 5MWClass box transformer，It can not only share mature box transformer technology and products，Load control can also be optimized，Sany Heavy Energy has become China“Upper box transformer”The leader of technological innovation。

AdoptLightweight design，While the power is greatly increased, the size of the product is not greatly increased.，Unit height、The width can meet the requirements of special transportation.；Its weight is about 30 tons lighter than that of the same grade products.，Maintain industry-leading level。

02Strict certification to ensure operational safety

The platform inherits Sany Heavy Energy 7.XMWPlatform excellent product performance，Optimize and upgrade on the basis of batch operation verification。

Before the product is offline，Sany Heavy Energy has been jointly debugged and tested with first-class parts manufacturers.，Component level product test validation，From gearbox to main bearings，Product temperature rise control、Noise reduction level、The vibration amplitude is better than the industry average.。

After the first wind turbine is offline，It will be sent to wind farms in Jilin Province for installation.，Type approval based on service conditions。In addition，Sany Heavy Energy will also carry out additional work on the unit.DVPTestValidate，This validation totals more than 1000 metrics.，The severity will exceed the general industry certification indicators.，Provide customers with high-quality products that can stand the test of actual combat！

Quality changes the world，Intelligent manufacturing leads the future。Sany Heavy Energy will continue to uphold“High、Big、Long、Light、Zhi”The concept of technology，Vigorously promote the transformation of digital intelligence，Accelerate technological innovation and product iteration，Continuously reduce the cost of electricity，Guarantee the rate of return on customer investment，High-quality development of wind power for China and the country“Double Carbon”Goal Realization Contribution Trinity Program、Trinity Wisdom。
